Asian Clam
Corbicula fluminea
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.
Asian Longhorned Beetle
Anoplophora glabripennis
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.
Autumn Olive
Elaeagnus umbellata
Autumn olive is a large deciduous shrub that can grow to a height of 15 ft, and a width of 20 ft. Its leaves are oval or lance-shaped with entire and wavy margins, dull green in color with silvery underside.
Balsam Woolly Adelgid
Adelges piceae
Adults are tiny (about 1 mm long) and appear dark purple to black in color. They produce a thick layer of light-colored, waxy, wool-like material that covers their body.
Beech Leaf Disease
Litylenchus crenatae mccannii
Beech leaf disease is a new threat to WNY and poses a serious threat to beech forests. Research is ongoing to learn more about the biology of this disease including its spread vectors.
Bighead Carp
Hypophthalmichthys nobilis
The bighead carp is a large, narrow fish with eyes that project downward. The body coloration is dark gray, fading to white toward the underside, with dark blotches on the sides.
Black Jetbead
Rhodotypos scandens
Black jetbead is a deciduous shrub that can grow up to 5 feet tall. It has bright green leaves that are opposite and doubly serrate with a rough leaf surface. It forms a dense shrub layer that shades out native species.
Black Locust
Robinia pseudoacacia
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.
Bloody Red Shrimp
Hemimysis anomala
The bloody red shrimp are translucent ivory-yellow in color, and exhibit bright red to reddish-orange coloring around the head and tail. The threat to the Great Lakes is currently not well understood.
