Pine Needle Scale
(Extension, Purdue University)
spacer
Common Name: Pine Needle Scale

Order: Homoptera

Family: Diaspididae


Pest Status: Pine needle scales can damage evergreen trees.

Appearance: Adult female covers are white, elongated, and tapered at one end. They are 1/10-inch in length. The male covers are smaller, white, and rectangular.

Life Cycle: After mating, the females begin to produce a white, waxy covering as they deposit their eggs. The eggs hatch in late spring and the crawlers seek feeding sites on the previous year's foliage. After a couple of weeks, the nymphs molt and continue to increase in size for about three weeks before emerging as adults.

Where to Collect: Although these scales prefer pines, they can also infest spruces and firs.
