It came out of one of the little goldenrod
blister galls I collected on 7/22/09.
It could be from one of these
pupae.
The amazing thing about this little fellow is that I chilled it, then froze it, then froze it for several minutes and finally, since it continued to be active, I dropped it in alcohol for a few minutes. The next day it was walking around.
From one of these galls
I found two more specimens, a little smaller than this one.
