Adelges tsugae

Pest description and crop damage Hemlock adelgids are aphid-like insects. They appear as white, woolly tufts on the bark and needles. Adults are black beneath the woolly material. Needles drop prematurely, weakening the tree and sometimes leading to death. Trees with severe infestations may be stressed, predisposing them to other insect and disease problems. The hemlock adelgid is especially a problem on hemlock hedges.
