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.

Tiger Beetle-Mimic Katydid (Condylodera tricondyloides) - DSC_1738#1a First look of Condylodera tricondyloides. Initially thought to be a tiger beetle mimicking a forest ant.

Tiger Beetle-Mimic Katydid (Condylodera tricondyloides) - DSC_1741#2 Higher view. The abdomen does indeed look like that of an ant!

Tiger Beetle-Mimic Katydid (Condylodera tricondyloides) - DSC_1743#3a Top view. The bulging eyes are typical of tiger beetles.

Leaf-Mimic Katydid (Chondroderella borneensis) - DSC_1622#15 This katydid was standing upright when we found it. As we approached, it sensed our presence and flattened it's body on the leaf!
