Concealed Pupa

23mm | January 20, 2011 | Armonia Nature Preserve, Limon Province, Costa Rica

I noticed a plant whose large leaves had been eaten right down to the leaf ribs. Curiously, portions near the tips had been folded over. I couldn’t resist opening one of those up.

The pupa shown above is what I found inside. The caterpillar’s last head capsule is still attached. The pupa is flipped in the photo above because I opened up the leaf. Normally it would be suspended inside by that thread.

For some reason, the head end of the pupa reminds me of a walrus’s head.

There were quite a few other folded-over leaves, but I was too late to find a caterpillar still fattening itself up.
