Dear AJ,
This is the ambulatory pupa of a Mantidfly.  Here is a matching image and additional metamorphosis images from BugGuide of the pupa of the Mantidfly
Dicromantispa sayi.  According to BugGuide, the larva:  “spins a cocoon, and changes to a pupa within the skin of the larva. Later the larval skin is cast; and, finally, after being in the cocoon about a month, the pupa becomes active, pierces the cocoon and the egg-sac, and crawls about for a time; later it changes to the adult form.”

  1. How long does the pupa stay ambulatory before emerging as an adult? I can’t imagine that they would be spending TOO much time walking around in what’s basically just a full body rubber suit.
