Identification & Distribution:
Viviparous apterae and alatae are small mottled green and yellow aphids with a rather even wax pulverulence giving an overall pale green colour. The abdominal dorsum in apterae is quite pale. Alatae have dark marginal and postsiphuncular sclerites and bands across tergites 7-8. The species is characterized by the combination of long very slender dusky siphunculi and a short thick blunt cauda. In apterae the siphunculi are 2.4-3.3 times the length of the cauda in apterae and 2.1-2.7 times in alates. In midsummer the progeny develop into dwarf apterae which live dispersed between the veins of the underside of the leaves. The body length of apterae is only 1.3-2.2 mm (dwarfs 0.8-0.9 mm) and of alatae 1.5-1.9 mm.
The small raspberry aphid does not host alternate. It only feeds on raspberry (Rubus idaeus) causing strong leaf curl in early summer. It is considered one of the most damaging pests of raspberry canes (Gordon et al. (1997) ). Sexual forms occur in autumn with apterous males. It occurs through most of Europe, west Siberia and in New Zealand and North America.
