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.
Japanese Earwig
A montane earwig found in the mountains of Japan, known for extreme maternal care. Females guard eggs and first-instar nymphs in burrows under stones.
Did You Know?
Japanese earwig mothers sacrifice their own bodies as food for their young — the nymphs consume the mother after she dies.
