Batesian Mimicry

In Batesian mimicry, a potential prey mimics another insect which it's predators would typically avoid. These "mimic models" could be unpalatable, or even aggressive so that a hungry predator that had experience with them before would avoid wasting time with such an unpleasant meal again.

We came across what looked like a tiger beetle, which looked like a forest ant initially, while some parts looked like a katydid. Upon closer observation, it was indeed a katydid (Condylodera tricondyloides) that was mimicking a flightless tiger beetle (Tricondyla sp.). The tiger beetle is typically an aggressive critter, and not an easy prey to catch.
