Dogwood - rosebay willowherb aphid

Aphis salicariae apterae are reddish brown with a marked wax bloom. The wax coating is heavier on the primary host making the aphids appear grey (see first picture below), but lighter on the secondary host so the aphids appear pinkish (see second picture below). The mid-dorsum of the Aphis salicariae aptera is more or less membranous but there are small postsiphuncular and marginal sclerites, dark intersegmental muscle sclerites and transverse bands across tergites 6-8. The siphunculi are gently to rather strongly curved outwards, and the cauda is short and bluntly tapering. The body length of Aphis salicariae apterae is 1.8-2.3 mm.
