INVASIVE SPECIES - A-Z
Asian clam is a freshwater bivalve mollusk. The outside shells are yellow-green to brown with elevated concentric rings. If the color chips away, white spots can be seen underneath. The inside of the shells may be light purple. Adults are small, usually less than 1 1/2" in length.
ALB has a glossy black body with white spots on top of the wings. Adults are 3/4" to 1" long. Antennae are roughly 2 times the body length with distinctive black and white bands. The legs and antennae have a bluish tinge. Adults are present from July to October.
Black locusts threaten prairies, savannahs and upland forests. They have an extensive root system that allows them to reproduce clonally, sprouting many clones in one area. As they grow, they'll form islands of dense canopy which shade out any plants below them.
