Lifecycle NotesThe caterpillar, known as the 'monkey slug,' has a unique appearance with its hairy, arm-like appendages. It pupates in a tough, oval cocoon that often incorporates bits of leaves or bark, resembling a small bird's nest or a piece of debris. The adult moth emerges in summer.
Identification TipsThe caterpillar is unmistakable due to its eight pairs of hairy, paddle-like projections extending from its body, giving it a 'tarantula-like' or 'hairy slug' appearance. Its cryptic coloration helps it blend with dead leaves.
Description
The image shows the distinctive caterpillar, which is brown and hairy with several pairs of fleshy, hairy, arm-like projections resembling shed leaves or debris. The adult moth is a small, stout-bodied moth with mottled brown wings.
