Trichapion rostrum
Trichapion rostrum, the baptisia seed pod weevil or wild indigo weevil, is a species of weevil in the family Brentidae. Description. Adult is entirely black. Its namesake elongated snout is called a rostrum, and has antennae attached near its base. Ecology. Adult females deposit eggs in seedpods of wild indigo (genus "Baptisia") plants; the larvae feed on seeds in the pods. Seed predation by weevils can adversely affect reproduction of the "Baptisia" host.
