Tomato Horn Worm Attacks!
August 4th, 2008I was out in my garden, and I noticed that a few of my tomato plants were nearly stripped bare of their leaves. I had noticed a few branches like this the other day, but couldn’t find the perpetrator. Well, I finally found the bugger — a rather large tomato horn worm
Rather than simply plucking the large caterpillar from the vine, and “removing” him from my garden, I had to do a photo shoot with him first. I’ve been quite fortunate in the past to not have to deal with many of these worms, and the ones I did were usually invaded by wasp parasites.
I didn’t realize at first that the horned part of the caterpillar is not their head. They have some incredibly convincing eye spots and markings to make it appear like they’re something you don’t want to mess with.
In fact, their head is the other end, which is much less intimating. They’ve got three sets of legs or feelers up front that help them to navigate the branches of my poor tomato plants.
Overall, their body stripes and coloration really make these attractive creatures. This particular fellow did a number on 2-3 of my tomato vines, but I’m hoping that they’ll rebound, despite already being a little bit behind this year. Does anyone else have any experience with the horn worms, and know how to keep them away in the future?

Horn worm — sounds like some magical creature that Hagrid smuggled into Hogwarts.

Um, yeah, it is. Just like my magic bean plants, which I’ll climb into the clouds!

I don’t think they are a bad thing. Here’s one I found a few weeks ago: http://www.tennessee-mom.com/archives/862
They don’t eat too much, I’m sure something will come along and find it a tasty snack… or use it for a home like mine.

btw that horn does make you think twice about going near it, does it? Great pictures, too!

They look terrifying blown up like that.

[...] we still have a number of tomatoes forming, so hopefully they’ll come around eventually; horn worms not withstanding. Unripe [...]

Kim, your picture is great. Unfortunately, the guy in my garden wasn’t impeded by wasp eggs, so he really did make a mess of some of my tomato plants. Thanks for the comments!

Great shots - all of those little eye spots are really something.
