Rearing caterpillars & frass champions

It's been a poopy hornworm day on both fronts--school and home. Hornworms are those ENORMOUS CAMOUFLAGED DEVOURERS wiping your tomato and pepper plants right off the map.

Caterpillar poop is called "frass", and hornworms are the Texas State Fair champions of frass. They would hold the Olympic World Title of frass if they cared about anything besides eating. They are so good at what they do naturally that it's frightening to consider the possibility of hornworms training with coaches named "Bela" and using performance enhancers.

Tomato hornworms [which are actually hawk moth caterpillars, not worms] are a major garden pest, so I went to the source for pest info, Insects in the City, for a factsheet. Scrolling down through the insect pests I found:

Caterpillars
Asps & Other Stinging Caterpillars
Rearing Caterpillars

This made sense in a confused super-cowgirl mindset. Hornworms do have those nasty pronghorns on their bezoozies. They rear up in a threatening manner then hold very tight when school kids are trying to pluck them off the tomato plants. I bet Slim Pickens could ride a rearing hornworm into a nuclear detonation, and it would still keep eating and creating frass.

Arabella Miller


Found this fresh, fun picture book on the New Book Shelf at my public library, and checked it out for my preschool class. The kids loved it, and I couldn't wait for them to ask me for an encore reading. You might say, "It has a good beat; you can dance to it," if it were on Preschool Bandstand with Dick Clark. The large format and clear, vibrant illustrations made it perfect for circle time.

I returned the book before I learned that "Little Arabella Miller" is a favorite British nursery rhyme and finger play. Clare Jarrett's picture book expands on the nursery rhyme to show the life cycle of the caterpillar.

There are several online sources for the words and actions of the nursery rhyme:

Little Arabella Miller had a fuzzy caterpillar (Tickle palm with two fingers)
First it crawled up on her mother (Walk fingers up left arm)
Then upon her baby brother (Walk fingers up right arm)
They said, "Arabella Miller! (Walk fingers up over head)
Put away your caterpillar!" (Hide hands behind back)

It would be fun creating a finger play for Jarrett's new verses. I hope Arabella arrives on your library's New Book Shelf. Check it out!

Ants day and date night

With no rats this time, and only one snake, the fourth Indiana Jones has to rely on insect vermin. We enjoyed the "Crystal Skull" movie immensely. It's taken a few hours for little nagging nitpicks to cut through the euphoria. Mostly I'm grateful for one last date with the dashing unmarried archaeology professor in the fedora. I'm willing to ignore some flaws for the chance to reminisce about our past adventures.

Indy's Russian foes have splendid difficulties with large computer-generated Peruvian ants. Certain parts of the movie seemed like Indiana Jones Joins Men In Black. I was hoping the "crystal skull" would resemble a Mayan inlaid stone mask more than the "galaxy in Orion's belt" cat collar!

Just the other day we learned of an invasion of "Crazy Rasberry Ants" in Houston. Crazy Rasberry is an indication of the ants behavior, and a salute to Mr. Rasberry, an exterminator who did battle with these ants.



The preschoolers have been checking the progress of the black swallowtail caterpillars eating the dill in our garden. When the caterpillars began disappearing, we hoped they were crawling off somewhere to make their cocoons. Unfortunately, the beautiful caterpillars are being attacked and eaten by fire ants. Nature can be such a bummer! The caterpillars need fedoras and whips against obnoxious ants.

Zits Pierce Caterpillar



My world is small. My students are small. Our discoveries and surprises are pretty big, especially with a digital macro camera setting. It's amazing how much life is going on inside the fence of a little preschool playground.

This caterpillar reminds me of Pierce, the much-punctured friend of Jeremy in the comic strip Zits. I don't know if it is an adolescent version of the stinging puss/asp/southern flannel moth caterpillar we found last fall. Pretty sure "Stinging Flannel Moths" would be a good name for a garage band, though.

Worming Its Way Into Snack?

Fresh vegetables were a tiny fraction of our diet back in Lincoln in the early Sixties. Except for carrot sticks and corn-on-the-cob, I thought the Jolly Green Giant and Del Monte put all veggies into tin cans. I willingly ate canned green beans, wax beans, niblets, cream-style corn, sauerkraut, and diced beets. Under duress I ate the minimum amount of canned peas. Sometimes Fritzi would serve canned lima beans or butter beans. Those were always suppers that led prematurely to bedtime. At Christmas and Thanksgiving we ate fresh celery sticks.

Nearly all my little students eat a wide range of fresh vegetables on a regular basis. Lunchboxes often hold sliced peppers, cucumbers, zucchini, tomatoes, edamame, broccoli, cauliflower, bean sprouts, sugar snap peas, and jicama.

In the upper elementary grades after 1964, I learned to eat chopped iceberg lettuce with Kraft Italian salad dressing, stewed tomatoes, and canned spinach with lemon or vinegar. It was high school before I ate baked squash. In college I pushed the limits trying fresh spinach, asparagus and mushrooms in some quiche/crepe fern-decor restaurant downtown. It was a wild and crazy time!

Sometime after I got married, but before I had kids I encountered eggplant and avocado. The charms of eggplant still escape me.

Tomorrow will be a challenge. My little students harvested the garden broccoli heads today. I've expended much attention removing the green caterpillars known as Imported Cabbage Worms from the broccoli plants over the past few weeks. The caterpillars are fiendishly camouflaged. When the broccoli florets are served with a dip of Ranch dressing, I will want to holler to the caterpillars, "I know you're in there! Come out with your hands up!"

Barbara Damrosch writing in the Washington Post, 7/5/07, calls those green larvae of the cabbage butterfly, "unintended garnish" and says they are harmless if accidentally consumed:

The green worms hide so well in the broccoli heads that you rarely see them until they are cooked, at which point they turn a conspicuous, incriminating white .... But there will always be a moment when you've just served an honored visitor a beautiful plate of homegrown broccoli and there's that little extra ingredient. Proper etiquette requires a guest to move it inconspicuously to the side of the plate and exclaim "Good protein!" if caught in the act .... Soaking produce in a sink full of salt water before cooking will send most worms flocking to the bottom.

Fritzi told me over the phone long distance that a salt water soak brought all the little creepies crawling out of a broccoli head. I can't recall why she actually began to use fresh broccoli in her kitchen. I was already married and living in Omaha, but we still had to live through Reaganomics before the first President Bush would proclaim his dislike of broccoli. By then my dad had decreed that he would not eat any salad that didn't have at least two ingredients besides the iceberg lettuce. That would be not counting the cabbage butterfly larvae.

"I do not like broccoli. And I haven't liked it since I was a little kid and my mother made me eat it. And I'm President of the United States and I'm not going to eat any more broccoli." George Bush, U.S. President (1990)

Ma Barker in the cabbage patch


Surveillance cameras captured this composite photo of Ma Barker laying eggs under the leaves of a broccoli plant in the school garden. She was creating a diversion while one of her sons, probably Lloyd, was chomping a big hole in the leaf of the next broccoli plant [lower right].

The real gang matriarch known as "Ma" had three other nasty outlaw sons besides Lloyd--Arthur, Fred, and Herman. This cabbage butterfly must have hundreds of voracious criminal offspring. They are all Public Enemies Number One in my mind.

Different opinions about how involved Ma was with the Barker-Karpis Gang have floated for decades. Alvin "Creepy" Karpis, who did time with Fred in the Kansas Penitentiary, became the leader of the gang. If you look at the vintage Ten Most Wanted posters in the post office you will see that "Creepy" was a velvety green caterpillar, same as the Barkers.

So I called up my dad. Sometimes I get fiction and memories intertwined. It seems like I heard tales of an outlaw car in Pierce. Did Dad remember ever seeing the shot-up car of Bonnie and Clyde on display at the Pierce County Fair? He didn't, but he did remember that the Anderson Garage had a classy car belonging to an outlaw named Flannery on display in Pierce for a long time.

Dad remembers hearing about the Chicago gangs, Pretty Boy Floyd, the Barkers, and John Dillinger as a kid in the Dirty Thirties. Dillinger changing his fingerprints with corrosive acid was a big story back then. Dad could get the latest news by wandering two blocks down to the Skelly station, and hanging around the cold water fountain at the sidewalk. "The Best Water in Pierce" drinking fountain was also the place to exchange news and gossip.

I'm ready for J. Edgar Hoover's FBI boys to conduct a four-hour shoot-out against the cabbage butterfly and her pesky broccoli gang offspring. I'm a tad irritable because, hey! I resemble that remark about Ma in an online biography:

ARIZONA CLARK "MA" BARKER (1871-1935) Person: In her younger years "Ma" Barker was a rather dumpy fiddle player and Bible reader. In her 50s she was even dumpier, running to gray hair and fat.

But I don't chew holes in the garden plants!

Preschool organic control of ICW




At recess the preschoolers rush over to the garden to examine the lacy damage to the broccoli and brussel sprout plants. They are excited, at least for these few days, to search for the offending imported cabbage worms (ICW), and quite willing to pick them off the leaves. Cupping the caterpillar in their palms, they run to the other end of the playground to release the very hungry caterpillars on different sorts of plants.

ICW are soft and unthreatening. If you were going to sew one, you would use a spring green sueded polyester fabric of just the sort your great granny might have for a special occasion pantsuit with elastic waistband for bingo nights at the assisted living center. Then you would stuff the polyester worm with old snagged knee-high nylons.

The preschool girls aren't the least bit squeamish about touching these cabbage granny caterpillars. The trick is to find the darn things! ICWs are perfectly camouflaged against the leaf veins. They are just as hard to see when they are an inch long as when they were at a quarter-inch. The five year old girls are getting better at this tricky sport. I can almost hear Curt Gowdy's breathy "American Sportsman" delivery commenting on the hunt.

The smaller girls are glad to hold, cuddle, and relocate the caterpillars. Interestingly, the preschool boys are only interested in this process if they can put a caterpillar in their pants pocket and take it home. O, ye snips and snails!

Like most of March Madness, I don't care who wins this game. Unfond as I am of brussel sprouts, cauliflower, and broccoli, I just enjoy watching the competition. I'm putting some J. J. Cale in the cd player. Eric Carle is playing Eric Clapton in the semi-final! I'm a lucky mom to have attended the 2004 Crossroads Guitar Festival at the Cotton Bowl with two of my sons!

Kale or Borecole is a form of cabbage (Brassica oleracea Acephala Group), green in color, in which the central leaves do not form a head. It is considered to be closer to wild cabbage than most domesticated forms. The species Brassica oleracea contains a wide array of vegetables, including broccoli, cauliflower, and Brussels sprouts. The Cultivar Group Acephala also includes spring greens and collard greens, which are extremely similar genetically.

Long hair, very cute, and dangerous

No, this isn't about teenage girlfriends! It's about the darling caterpillar we found near a big oak tree. We coaxed it into a bug box, but couldn't identify it that night. It was quite distinctive with its orange fauxhawk Mohawk hairstyle, orange curled tail, and baby sloth face.

Not knowing what it needed to eat, we couldn't keep it until it formed a cocoon, so we released it at the foot of the oak tree. It curled into a cute, cuddly ball.

We kept a polite distance, and let it uncurl when it was ready. Off it went climbing the tree, with us watching until we could no longer see it moving camouflaged against the bark and about twenty feet high.

Thankfully, no one ever petted our cutie. Last night I finally had a chance to identify it. It is one of the most poisonous of stinging caterpillars, so we were very lucky that no one got hurt!

The "asp" or puss caterpillar of the southern flannel moth, Megalopyge opercularis, is considered the most dangerous caterpillar in the U.S. The skin irritation can last from one hour to five days! It is found from Maryland to Mexico across the Southeast U.S. "Asp" is its Texas nickname, and the
Texas A&M Cooperative Extension field guide makes clear that it is more snake than puddy-tat. If, like me, you didn't even know there was such a thing as a stinging caterpillar, you'll be interested in the eMedicine information. As if we didn't have enough to worry about, there can be epidemics caused by airborne caterpillar hair dispersion! The North American Moth Photographers Group has excellent photos of the entire life cycle of the southern flannel moth.

And if one of them starts calling and text messaging your teenage son, be afraid. Be very afraid!

Perfect timing

Ten beautiful butterflies emerged from their chrysalids inside the net tent this morning providing a fabulous experiential lesson for the preschoolers. They are absolutely gorgeous, and very wise!

The first day of school we found caterpillars devouring the leaves of our sunflower in the school garden.

The second day of school we collected the caterpillars inside a bug box.

The third day of school we fed the caterpillars in the bug box more sunflower leaves after we looked at the butterfly eggs on the leaves with a magnifying glass. We got out the butterfly books and tried to learn what these caterpillars might become.

The fourth day of school the caterpillars crawled to the top of the bug box, hung upside down like the letter j, and made their chrysalids. These caterpillars were writing the lesson plans!

After the three-day weekend, the lessons continued.

The fifth day of school we tried to dismantle the bug box so the butterflies could emerge into our class butterfly tent made of netting and wire. The screws were too rusty, so we cut away the screen, and put the whole bug box into the tent. We tried to be very gentle. The students chose to do work about the life cycles of butterflies and sunflowers, and every other insect project and puzzle in the classroom.

The sixth day of school we waited and wondered when or whether we might see butterflies. We talked about artists; how they observe, analyze, document, research, interpret, and add imagination. We observed the remaining sunflower plants, then made drawings.

The seventh day of school the first butterfly emerged just as the students were arriving. It hung very still for awhile, then slowly began moving its wings. The other nine emerged over the next hour and a half. They crawled around on the net as they gained strength. They visited the blossoms and sugar water, and began to fly around the tent.

Then a butterfly escaped and flew right onto a student's cheek! It was caught gently, and released out the door. Another escaped during storytime! We put a strawberry basket over it, then released it.



Two more got out, and one flew into the restroom. The lead teacher and at least a dozen curious preschoolers jammed into the two-stall restroom to rescue the butterfly. We took it to the playground to release, and it flew two circles around the kids. The caterpillars wrote the lesson plan, and the butterflies gave the demonstration!

The eleventh butterfly did not survive. It seems to have emerged missing some essential parts, fallen to the bottom of the bug box, and died. We will retrieve the wings, and save them in the class insect center. We will have to talk about death and survival in another caterpillar lesson plan, and answer questions for awhile. That is a gift, too.

All the parents came to our back-to-school meeting this evening, and got caught up in the butterfly excitement. Again, the timing was perfect. The class experience became a shared family experience.

Tomorrow morning we may have six checkerspots to release from the tent out on the playground. Or we may find that some have escaped, and are flying around in the school. We will hold open the doors and sing, "Glory hallelujah!" What a blast into the school semester!

Many preschoolers have already viewed hours and hours of marching penguins, crocodile hunting, meerkat family feuds, animal rescues, Galapagos tortoises, shark specials and poison dart frog features. Most first graders know they should worry about rain forest devastation and melting polar ice. Not many of them have spent significant time chasing fireflies, watching roly-polies, holding ladybugs, or looking for caterpillars. Nature is something they see at its most extreme and distant on television or computer programs. It's not wiggly or warm or wondrous or personally experienced in the grass near their toes.

It's likely to rain tomorrow. The kids expect the tornados of the Storm Tracker videos, with a hurricane, tsunami, or a West Nile virus epidemic. Rain is for sitting on the front stoop and smelling the change in the air, for listening to the approaching thunder, for noticing the light as it becomes more greenish-gray, for twirling about in the yard as the first drops cool your arms and forehead. Rain is for washing away the sidewalk chalk and for wondering where the butterflies go.

Pack up your troubles in your frass leaf bag

Can't get all that worried about the munched canna leaves on my patio. A leaf roller caterpillar is having a splendid feast. Once I've identified it, I'm glad to sit back and enjoy its show. Plus, I got two plastic resin Adirondack chairs for $6.44 each at Home Depot this morning. My old plastic patio chairs migrated to a student apartment in Lubbock, but didn't complete the return journey. Now I can sit out on the patio and contemplate what to have for dinner instead of fresh asparagus.



This caterpillar will roll up to create a lovely leaflike chrysalis. I hope it will pupate in my glass jar, but it is filling the jar with frass at a disturbing rate.

Pack up your troubles in your old kit-bag,
And smile, smile, smile,
While you’ve a lucifer to light your fag,
Smile, boys, that’s the style.
What’s the use of worrying?
It never was worth while, so
Pack up your troubles in your old kit-bag,
And smile, smile, smile.


Been having flashback nightmares to late Seventies weddings lately. Qiana. Jim Croce. Doubleknit. Powder blue. Platform shoes. I don't want to save time in a bottle. I just want to keep the caterpillar in the jar until I know a little bit about it for my files.

We'd like to know a little bit about your for our files
We'd like to help you learn to help yourself.
Look around you all you see are sympathetic eyes,
Stroll around the grounds until you feel at home.

If I could save time in a bottle
The first thing that I'd like to do
Is to save every day 'til eternity passes away
Just to spend them with you

Ramble on, hornworms

On the phone with Dad, discussing Hy-Vee chef salads, Swanson pot pies, humidity, and no-name golf, when I spy the tomato hornworm hiking across my concrete patio. It's lost, but making very good time. No tomato plants here! Hornworm movements are hiking in anti-gravity boots on a Seventies' waterbed. A rambling hornworm should be accompanied by a merry-go-round calliope version of Led Zep's "Ramble On":

Ramble On,
And now's the time, the time is now,
to sing my song.
I'm goin' 'round the world,
I got to find my girl,
on my way.
I've been this way ten years to the day,
Ramble On,
Gotta find the queen of all my dreams.

Before the phone call is over, a second hornworm traverses the patio, again left to right. True, it could be the earlier lost immigrant on a second circuit searching for Heffalumps. Maybe I'm in Wonderland without my pocket watch.

Hot on the trail of caterpillar frass

My cannas have rarely looked lovelier. The leafrollers never showed up to roll the leaves with their sticky white goo and eat holes through the "cigars" this summer.

Just as I was celebrating, my creeping myrtle aka periwinkle aka vinca minor leaves became folded, brown, and brittle. This never happened before. The leaves reminded me of the powdery mildew on flowering crape myrtles (completely unrelated to creeping myrtle). That put me off the trail briefly, though I really suspected an obnoxious, poopy insect.

My little students are fascinated with the tomato hornworms that hide in our school garden. Hornworms are frass champions, meaning they can outpoop any other insect and many small mammal pets on any given day. My patio pests aren't hornworms.

What kind of insect goes to the trouble of neatly folding and gluing itself inside a leaf just to suck out all the green food goodness and leave frass in the living room before vacating the premises for the next leaf on the vine? Okay, it does remind me of some rugby players I knew in college who would throw major parties to get evicted instead of paying their rent. This insect is not large enough to carry the beer kegs into the rental house, though.

Yesterday I attacked the ugly plants to work out unsuccessful water heater service frustrations. Hacked the vinca way back, and bagged it, along with other overgrown plants in a sweaty machete mama therapy. I left enough periwinkle for it to revive, but not much for pest food. I only spotted one likely villain. The little yellow and green caterpillar with black spots, an orange head, and a Groucho Marx leer disappeared too quickly.

Today I wanted to catch Groucho in the act. I followed a series of frass-filled brittle ruins of former leaf room-&-boards to a still-green and moist folded leaf flophouse. Yes! This dude has played his last rugby game! No more free rent. No more beer and Cheetos. He's spending the rest of his days in a periwinkle-filled Ragu jar with tiny holes in the lid. I may have to play good cop/bad cop to learn why Groucho went for the vinca this year, instead of the cannas.

What do you do about leaf-rollers on Cannas, Vinca Minor and Vinca Major? Parker County Master Gardener La Donna Stockstill

...Damaged canna blades become notched and ragged. When they mature and open, they look like someone has shot them with a B B gun. One finds robust caterpillars hidden inside leaf rolls. Canna leaf-roller caterpillars are clear white at first. They become semi-pale green with age. Lesser canna leaf-roller caterpillars are smaller and yellow. Large ornate butterflies lay eggs from which they hatch. The caterpillars spin silk thread used to pull leaf edges together. They hide inside the protective tube, presumably to avoid predators. Leaf rollers in late summer are devastating to foliage of vinca major and to some lesser degree to vinca minor and should be prevented with systemic insecticide before they begin... If the damage has been done, you will may want to cut the marred foliage back and allow new growth to cover the area ...

You may want to check references before renting to rugby players, too.

Velour Caterpillar

After the big storm of Wednesday night, the students found an impressive caterpillar on the playground retaining wall Thursday. Over three inches long, it looked like it had been sewn of dusty gray velour exactly the color of the nozzle attachments for my mother's 1950s cylinder vacuum cleaner. Down each side was a soft gray fringe that could have been the mustache of the Muppets' Swedish chef. Never imagining the caterpillar would be easy to find again on Friday, I didn't take my camera. It had only crawled two feet.

The search for identification led me to two very useful sites. The first is Discover Life, which can be used to ID all sorts of living things. The search function of the IDnature section let me choose up to four characteristics. It took me awhile because I didn't know that the "fringe" is very aptly called "lashes". The only close photo was the larva of the American lappet moth. Our playground visitor had two bands of dull, rusty gold, instead of the bright red bands.



Phyllodesma americana, larva Dave Wagner / Discover Life

Once I had a name, I was able to find this photo by Jo McGavin on BugGuide.net, another useful site. You have to look at it awhile to realize what you're seeing!



I can't publish John Davis' photo of the adult stage lappet moth, but Phyllodesma americana has some nifty camouflage tricks. Davis is a retired U.S. Fish and Wildlife Service biologist. He has a Flickr gallery of excellent moth photos, and contributes to the Digital Guide to Moth Identification's North American Moth Photographers Group.



I hope we can all identify the Swedish chef making chocolate mousse!

Mom's vacuum was silver gray and just right for little kids to ride. It is not as easy to identify as the caterpillar, although I spent too much time trying. Her well-used copy of Guide to Easier Living taught her that vacuuming was a once-a-week task to be done on Thursday. I'm sure she selected it with this explanation in mind:

The choice of model--whether it's upright, canister, or cylinder--depends on the amount of carpeted area versus hard-surface floor area in the home. The two latter types have swivel arrangements that permit one to reach all parts of a room from one central position. For large carpeted areas, the upright is preferred because motor-driven brushes get deeply embedded dirt out of the rug fibers.

From the Great Achievements page of the National Academy of Engineering:

In 1907 an American inventor named James Murray Spangler created a vacuum cleaner that basically consisted of an old-fashioned carpet sweeper to raise dust and a vertical shaft electric motor to power a fan and blow the dust into an external bag. Manufactured by the Hoover Company, which bought the patent in 1908, it was hugely successful, especially after Hoover in 1926 extended the fan motor's power to a rotating brush that "beats as it sweeps as it cleans." Meanwhile, the Electrolux company in Sweden grabbed a sizable share of the market with a very different design for a vacuum cleaner—a small rolling cylinder that had a long hose and a variety of nozzles to clean furniture and curtains as well as carpets.




Our vacuum was similar to the Electrolux at left, but not quite the same in my memory. For one thing, no kids are riding on it.
