Winter Species

The species listed below are predominately detected during the winter months in New York State.  Contact your local PRISM to find out what priority species have been identified for your region. 

Hemlock wooly adelgid

(Adelges tsugae)

The hemlock woolly adelgid (HWA, Adelges tsugae) is an aphid‐like,  invasive insect that poses a serious threat to forest and ornamental hemlock trees (Tsuga spp.) in eastern North America. HWA are most easily recognized by the white “woolly” masses of wax produced by females in late winter, found at the base of the needles on the underside of branches.
