[Tweeters] OT Yellowjackets & Tent Caterpillars

[Tom and Carol Stoner]

At Nisqually today, out on the dike, I noticed a yellowjacket caught in a
tent caterpillar web.  It wasn't trapped but trying to get through the silk
and inside.  As I watched 2 more showed up and worked their way in.  It
seemed like they were after the frass left behind by the caterpillars.  One
of them actually grabbed a small chunk of dark material in its mouth.  I
didn't see any caterpillars in the nest.  None of the other tents I
examined on my way out to the boardwalk had yellowjackets trying to enter.

Any ideas about what the yellowjackets may have been up to?
