Spiny Looper (Phigalia titea) vs. Ant
I saw dozens of these caterpillars on deciduous trees in this forest. They were everywhere. The caterpillar in this photo was have an unlucky day. It was still alive, battling the ant, but it was losing the fight and was leaking hemolymph (insect "blood") from multiple spots on its head and body.
