Description and Identification


Silver Spotted Skipper Caterpillar

Silver Spotted Skipper Larvae

The larva has a segmented body, with each segment alternating with peach-orange and beige. The head is dark brown to black, while the tiny legs are dark orange in color. As they age, they gradually turn bright yellow, with the head turning bright red with two distinct yellow spots resembling eyes (as an adaptation to scare off predators). They survive on several woody legumes from their host plants.

The pupae are relatively flatter, and with a dull gray-yellow to rusty brown coloration, that perfectly blends with the dry/dead leaves of the host plants.
