Hag Moth

A furry brown moth whose larva is called the monkey slug due to its bizarre shape with curly fleshy lateral projections. The caterpillar looks nothing like a typical lepidopteran larva.

💡

Did You Know?

The caterpillar's curly brown appendages are thought to mimic a shed tarantula skin to deter predators.

Rothschildia Silk Moth

A spectacular large moth with rich brown wings featuring prominent triangular translucent windows. The wing shape and pattern create an effective leaf-mimicry at rest.
