I can't believe I found these so quickly.  I found three of these guys, one on my tomatoes, two on my eggplants.

Hard to believe they grow from this

into this (look at the larva picture on the right):

Aren't they ugly?  I remember my mom finding them on her tomatoes.

I see your article wants you to feed them :)

Call me weird, but I love hunting for those buggers! Did you know that if it's quiet out you can hear them clicking at you when you shake the plant? It gives them away every single time. ;-)

You know, my friend and I landscape together, and last year we found some of these on a job and kept them.  They travelled around with us, and even though they're bad...  We kind of really liked them. 

if you find white things on top of them...it is another insect's eggs (fly of some type I think) which when they hatch will feed on the hornworm itself....

They were almost cute at this size, except for the holes eaten in the leaves. Grrr.

I hadn't read the article, I was really just looking for a good picture.  Might be a good science project.

I **heart** caterpillars!  Tomato plants I had growing on the deck had a bad infestation of tomato hornworms about 5 years ago.  Never had a problem since that one incident.  The caterpillars that are around rarely eat so much that they ruin the plant, just leave the leaves a little tattered. ...Except for some fernleaf dill that I was growing last year.  But I grew the plant specifically for butterflies and caterpillars.  I enjoyed seeing the caterpillars munching on the plant, and grow bigger and bigger.  Unfortunately (or fortunately, depending on how you look at it) an eastern bluebird showed up and gobbled all the caterpillars up.

Hmm, choosing between a bluebird and caterpillars.  That's tough.  (It's been years since I've seen a bluebird!)

I checked my pitiful potted tomato but only found a grasshopper.  DH potted it and it's very soggy.  The weather hasn't been good anyway.  I sowed some marigold seeds with it, hoping that they'll sop up some of the water but I don't think that's really a solution. 

I think they are cute!
