A field study found that mounds shaded from direct sunlight stayed much cooler, probably cool enough to slow the development and reproduction of the colony. Their mounds are made mostly of soil and produce little heat of their own, so the ants depend on the sun, which is why the mounds sit in open, sunny grassland and can last for many years.",{"question":226,"answer":227},"How long can a Lasius flavus queen live?","A very long time. A lab record of 22.5 years is reported for a Lasius flavus queen, among the longest lifespans recorded for ant queens. A healthy colony can therefore last for many years.","Small workers of a clear yellow to brownish-yellow color with tiny eyes, living almost entirely underground or under stones in grass; unlike the similar Lasius umbratus, they have no erect hairs on the antennal scapes and shins. The queen is light to dark brown with a paler underside, so she is often mistaken for a Lasius niger queen.","en",{},true,[233,236,238,240],{"kind":234,"text":235},"tip","In the wild they live mostly on honeydew from root aphids, so keep honey or sugar water on offer whenever the colony is active and add small soft insects, like fruit flies, for the brood.",{"kind":234,"text":237},"They are soil dwellers that suffer when the nest dries out.
