Nice image of the most well recognized skipper in N America.   Your image 
encouraged me to read about them again including their 'pillars.

Insect frass may provide chemical cues for parasitic wasps to the location of 
prey insects.   Many caterpillars that live in leaf nests, including the 
silver-spotted skipper, forcibly eject their frass for considerable distances 
to eliminate these chemical cues. Silver-spotted skipper larvae utilize their 
anal comb to throw their frass a distance up to 38 body lengths!!   

Staying out of the way,  Mike
