Spirea aphid

The spirea aphid is the dominant aphid species on apple in Israel and China and is found more often than green apple aphid in some Washington State orchards. 

Hosts
The apple aphid can occasionally colonize pear and hawthorn, but its primary host is apple.

Life stages
Egg: The egg is shiny, black and roughly the shape of a rice grain but only about 1/50 inch (0.5 mm) long. It cannot be distinguished from the egg of two other species, rosy apple aphid and apple grain aphid, that overwinter on apple.
Nymph: The nymph is yellowish green to dark green, about 1/16 inch (1.5 mm) long.
Adult: The wingless adult green apple or spirea aphid is bright green with black cornicles, legs and antennal tips. The winged adult has a black head and thorax with a yellow-green abdomen. Both winged and wingless forms are about 1/8 inch (3 mm) long.
