Lawn nesting will eventually become obvious as the aphids clear sections of grass or portions of gardens.

[1] The yellow meadow ant feeds on the honeydew from root aphids, which they breed in their nests.

Evidence of their underground lives is their lack of pigmentation and the smaller size of their eyes,[3] compared to closely related species like the black garden ant.

Alates (winged, unmated queens and males) can be seen on warm days and evenings of July and August.
