Good to know

Six things about the hoverfly

Disguise

A fake wasp

The stripes copy a wasp's warning colours, so birds leave it alone. But a hoverfly can't sting at all.

Flight

Hanging in the air

Hoverflies can hold perfectly still in mid-air, even in a breeze, then dart off faster than you can follow.

Babies

Aphid hunters

The maggot-like larvae of this hoverfly eat aphids, lots of them. Another friend for gardeners.

Flowers

Busy pollinators

The adults feed on pollen and nectar, which makes them important pollinators alongside the bees.

Travel

Long-distance flyers

Billions of hoverflies fly in and out of Britain each year on long migrations.

Wings

Count the wings

Hoverflies are true flies, so they have just two wings. Bees and wasps have four.

How to spot one

Look for a small wasp-coloured fly hanging perfectly still in the air over flowers or in a sunny gap between plants. Unlike a wasp, it has big eyes and only two wings.

Lend a hand

How to help

Grow flat, open flowers such as fennel, yarrow and marigolds. Their larvae eat greenfly, so leaving a few aphids on your plants feeds the next generation.
