From the Academy of Science – St. Louis BioBlitz at Emmeneger Park:

“…the Nematocampa resistaria, the so-called horned span worm.  I have seen it just once previously on Missoui oaks, my primary focus.  As you can see from the photo, it is quite distinctive, with four dorsal filaments, that can extend out and then be drawn in, depending on how much you pester it.  We have looked at literally 10’s of thousands of caterpillars since 1993, and this is the first that we have seen since then.”
-Robert Marquis, Ph.D.

“This was an amazing opportunity; these hands-on activities inspired a level of
student engagement that I have never experienced before”
