Small black ant (Lasius niger)

Biology:

The female workers are 3-5 mm long. Their colouring varies from black-brown to brown. Nests are built in gardens, under rocks, in lawns, under house terraces, in wall gaps, tree bark, etc. These ants often use plant lice as a source of food. They suck up the sugary excretion of the lice, the honeydew. The small black ant is the commonest ant species in house and garden.

Damage:

The damage done by this species is similar to that of the turf ant. Since ants also feed on honeydew from plant lice, they in some cases contribute actively to their proliferation and spread.
