This past weekend a group of us went over to Glacial Lakes State Park for some hiking and a change of scenery (i.e. trees). During our hike we passed a few sections of remnant prairie, evident by the presence of lead plant (Amorpha canescens). One of these had what appeared to be a flowering Echinacea angustifolia. Due to a combination of curiosity and habit, I walked over to check the plant for aphids. Sure enough, there they were:
They looked like Aphis echinaceae, though they were slightly bigger than the aphids I've seen around here. The reason I mention this is that the specimens for Aphis echinaceae were collected in our field sites throughout Douglas County. Glacial Lakes State Park is a little under 30 miles away. I didn't collect any aphids, but I thought it was an observation worth sharing.
