Trash or junk bug - closeup, Orito, Colombia

Trash bugs are the larvae of lacewings, of which some show the behavior of collecting debris on its back to protect against predatory lady beetles, who are after the same food: aphids. The trash on their back includes their own egg shells, various pieces of random debris and usually body parts of its many past victims.

They are tiny, very fast and known to traverse huge distances to find prey. Here's a video of how we discovered it:

From most angles, you'd see part of the legs at most, the rest covered up by the debris but here we got lucky that it showed its awesome head.
