Fig. 204. Aphis spiraecola 
Collections. On leaves and twigs of Spirea van houttei and S. sp., Helichry- 
sum sp., Viburnum opulus var. sterile, Cosmos bipinnatus, and Prunus japonica. 
Throughout region. Fundatrices April 21, apterous summer viviparae May 15 to 
Oct. 25, alate viviparae May 15 to Oct. 25, oviparae Sept. 2 to Oct. 28, males 
Sept. 2 to Oct. 28; very common. 
This species has been considered as only a race of the same species as A. 
pomi (Patch 1929:689). In the viviparous forms the Spiréa aphid is distinguished 
from the apple aphid only by the smaller size and this character intergrades, 
but in the sexuales distinct differences occur. The alate form of the male and 
the dark colored, distinctly swollen closely sensoriated hind tibia of the ovipara 
on Spirea (Patch 1923a:56) seem to clearly distinguish this form from A. pomi.
