Good to know

Six things about ants

Trail

Follow the scent

A worker that finds food lays a scent trail home. The others follow it, which is why ants walk in lines.

Farm

They keep livestock

Ants guard greenfly from ladybirds and stroke them to get a drop of sweet honeydew in return.

Flying

Flying ant day

On a warm, still day in July or August, winged queens and males pour out of nests all over a district at once.

Queen

A long reign

A queen black ant can live for fifteen years or more, and one in a laboratory reached twenty-eight.

Strength

Small but mighty

An ant can carry many times its own weight.

Family

Relatives of bees

Ants belong to the same great group of insects as bees and wasps.

Out and about

How to spot them

Lift a flat stone on a warm day and you may see workers rushing white cocoons underground. Put it back gently.

Lend a hand

How to help

Ants tidy up dead insects and air the soil. If they come indoors, clear up the crumbs and block the gap: there is no need to wipe out the nest.
