Tawny Emperor Caterpillar

As everyone knows, the CB is blessed with an abundance of emperor butterflies, both hackberry and tawny.  Yet Ray has failed to espy any caterpillars.  Until now.  And here it is, a tawny emperor caterpillar.  Alas, it appears to have a few ectoparasites in the vicinity of its "neck".   Soft hearted Ray was fixing to squeeze the bejesus out of the parasites with tweezers.  But by the time Ray found the tweezers, the caterpillar had departed for parts unknown.
