Stinging slug caterpillar (likely a limacodid)

Usually found on the leaves of trees and shrubs in forests, gardens, and other vegetated areas, especially in tropical and subtropical regions.

The caterpillar feeds on foliage; adults generally feed little or not at all.

Limacodid caterpillars have flattened, slug-like bodies and conspicuous clusters of spines. They pupate in tough cocoons; the spines of many species can sting on contact.

Spines may cause painful skin irritation, so avoid touching it. It is part of the food web, though large numbers can damage plants.
