English grain aphids are larger than greenbugs and have a "spidery" appearance due to their long legs and narrow, long cornicles (tail pipe looking projections on the rear of the aphid). The body of the English grain aphid is green, but the cornicles and much of the legs are black. The English grain aphid is commonly found in the heads of wheat but seldom reduces yield, and insecticidal control is not recommended.


Insecticidal control is never recommended for the English grain aphid, for more information visit OSU Fact Sheets.
