Hickory Horned Devil

what is this?
Hey Bugman! My daughter and I saw this bug/worm (pic enclosed). Thought it may be a tomato bug but much larger than I’ve ever seen and what about the horns? Hope you can help. Thanks,
Brent Connors

Hi Brent,
The fierce looking but harmless Hickory Horned Devil is generally regarded as North America’s largest caterpillar. It has probably come down from the trees where it has been feeding so it can burrow into the ground to pupate, the next step in its metamorphosis into the lovely Royal Walnut Moth. We have had readers say the Hickory Horned Devil resembles a Chinese Dragon.
