Tortoise Beetle larva - side view, La Isla Escondida, Colombia

I kind of screwed up this observation because during the spotting, I had no idea what I was photographing, which way is front or back, and what to focus on. Only after seeing this post by Christine...

...did I realize the subject and its anatomy :) To paraphrase the information from Christine:

"The larvae of the Golden Tortoise Beetle have broad, flattened bodies that are adorned with branched spines. They carry their cast skins and fecal material on their back - attached to spines arising from the posterior end of their body, a structure called an "anal fork." The anal fork is used to hold the debris over the back of the body, forming a fecal shield that deters predation."

Quite a missed opportunity to capture it better! I'm not sure if this specifically is the Golden Tortoise Beetle or another species of Tortoise beetle. Looks like I managed to capture the "anal fork", a top view with the head misfocused, and a side view with accidentally some of its head in focus.
