Evergreen Bagworm Moth
A North American bagworm whose larvae construct spindle-shaped bags covered in bits of leaves and twigs. Heavy infestations can completely defoliate and kill ornamental evergreen trees.
Did You Know?
The adult female is so reduced that she is essentially a bag of eggs with no wings, legs, eyes, or functional mouthparts.
Case-bearing Leaf Beetle
A brilliant metallic green to golden beetle with a cylindrical body shape typical of case-bearing chrysomelids. Adults are commonly found on flowers and leaves in sunny meadows.
Did You Know?
Larvae construct a protective case from their own fecal material, which they carry around and enlarge as they grow, much like caddisfly larvae.
