What's That Bug? does not endorse extermination

Horned Spanworm
April 18, 2010
Thanks for all the help you’ve given me! But here’s one I found myself that I’d like to share: a horned spanworm (OK, I’m pretty sure that’s what it is). I found it lurking on a maple seedling, and from what I’ve read, was probably responsible for the chew marks on several of the maple leaves (primary habitat is deciduous and coniferous trees). It is interesting to note that between the first picture and the latter pictures, the ‘tentacles’ continued extending (must be camera shy). I found the textured orange patch on his upper back very interesting; I saw it on few of the other photos I viewed. Also, it was very reluctant to uncurl.
Enjoy!
