Soybean aphid

Aphis glycines

The soybean aphid, a native of Asia, has been in the Midwest since 2000 and has quickly become the most serious pest of soybeans in much of Indiana. These aphids are small (less than 1/16" in length), yellow-bodied insects with distinct black cornicles, and may be either winged or wingless. They are typically slow-moving and often found on the underside of the newest growth on a soybean plant.
