Palmetto Tortoise Beetle Frass

Description:

approx. 3/4 inch

Habitat:

spotted on underside of cabbage palm frond

Notes:

Upon hatching, the young larva begins to excrete strands of dry feces that curl up over its back and accumulate to form a dense thatch-like shield. Larvae have an anal fork to hold the fecal shield in place. The fecal shield has been shown to be an effective defense against a predacious larva of Cycloneda sanguinea (L.) (Coleoptera: Coccinellidae) and the predacious stink bug, Stiretrus anchorago (Fabricius) (Hemiptera: Pentatomidae).
