Mimicry..

It mimics dead leaf part and also when threatened it will behave like an Black Ant...

The caterpillar features spindly forelegs and a swollen abdomen that curves up at the end, resembling a lobster tail. If the Lobster Moth Caterpillar is provoked, it spreads its front legs and arches its head back, possibly spraying formic acid. As an adult moth, it simply flies away.

Notodontid larvae are notable for their often bizarre shapes, and some have chemical defenses (cyanic acid, formic acid, and other ketones: Blum, 1981) not commonly found in other Lepidoptera (Weller 1992). Schizura unicornis and S. badia have a mixture of formic acid, acetic acid and other compounds which they spray accurately at their attacker (Attygalle et al., 1993).
