Publisher's Synopsis
Excerpt from Cooperative Economic Insect Report, Vol. 16: October 28, 1966
Samples collected July 7 in Maine and July 11 in New Brunswick consisted entirely of viviparous forms. In the New York collections, taken in August and September, however, the majority of specimens were oviparous females, but a few males and viviparous females were present. In all collections that I have examined, the aphids were densely clustered on the terminal growth of the vetch (principally on the stems but with a few on leaves and seed pods), nymphs were more numerous than adults, the insects were not attended by ants, and there was no evidence of para sitism.
