Good to know

Six things about the elephant hawk-moth

Name

An elephant's trunk

It's named after its caterpillar, whose long front end looks like an elephant's trunk.

Defence

A snake in the grass

When scared, the caterpillar swells up its front, showing big eyespots that make it look like a small snake.

Colour

Pink and olive

Few British moths are this colourful: rose pink and olive green, like a sweet from a jar.

Night

A dusk flyer

It feeds on honeysuckle and other flowers as the light fades.

Eyes

Colour vision at night

Scientists found it can see colours in light so dim that we would see only grey.

Food

Willowherb and fuchsia

The caterpillars feed on rosebay willowherb, and on fuchsias in gardens.

How to spot one

Look round honeysuckle at dusk in June and July. In late summer, search rosebay willowherb and fuchsias for the big brown caterpillar with eye markings.

Lend a hand

How to help

Leave some rosebay willowherb to grow, and plant honeysuckle for the adults. Turn outside lights off when you can.
