Green Milkweed Leaf Beetle
A large, handsome beetle with blue-black elytra marked with orange to cream-colored spots and a blue-black pronotum. It is commonly found on milkweed plants across North America.
Did You Know?
Like monarch butterflies, this beetle sequesters toxic cardiac glycosides from milkweed, and its bold coloration warns predators of its unpalatability.
Cowpea Weevil
A small, reddish-brown to dark beetle with mottled elytra and a prominent pygidium bearing two dark spots. It is one of the most destructive pests of stored cowpeas and other pulses.
Did You Know?
Females glue their eggs directly onto the surface of bean seeds, and the larvae bore into the seed immediately upon hatching.
