Good to know

Six things about the elephant hawk-moth

Name

Named for its caterpillar

The caterpillar's front end tapers like an elephant's trunk.

Trick

A snake's head

When alarmed, the caterpillar pulls in its trunk and its front swells, showing four big eye-spots like a small snake.

Pink

Pink and green

Few British insects are as brightly coloured, yet hardly anyone sees it, because it flies at night.

Dusk

It sees colour in the dark

Its eyes can tell colours apart by starlight, which helps it to find flowers.

Hover

It hovers to feed

Like its hummingbird cousin, it hangs in front of honeysuckle and drinks with a long tongue.

Garden

A fuchsia eater

The big brown caterpillars are often found on garden fuchsias in late summer.

How to spot one

Watch honeysuckle at dusk in June. In August, look for the fat caterpillars on willowherb and fuchsia, often at head height. Take an adult with you.

How to help

If you find a large brown caterpillar with eye-spots crossing a path in September, leave it: it is looking for somewhere to bury itself for winter.
