The stag beetle that follows you

This page is the damp ground round a pile of old logs. Move your pointer and your bug will scuttle, trundle or burrow after you. Choose a different bug at the bottom, and tap the notes to open them.

01 · AntlersJaws like antlers

The male's huge jaws are for wrestling other males. He tries to lift his rival and tip him over.

02 · BiteMostly for show

For all their size, the male's jaws give only a weak nip. The female's small ones are stronger.

03 · GrubSix years as a grub

The fat white larva lives in rotting wood underground for up to six years before it becomes a beetle.

04 · AdultA few weeks as a beetle

After all that, the adult lives for only a few weeks in early summer and hardly eats.

05 · FlightA noisy flier

On warm evenings males fly in search of females, upright and clumsy, with a loud hum.

06 · RareRarer than it was

Tidying away dead wood has made it scarce. It is protected by law.

Six ways to help log pile bugs

Logs

Build a log pile

Stack a few logs in a shady corner and leave them to rot. Part-bury the bottom ones for stag beetles.

Leaves

Leave the leaves

Rake fallen leaves under a hedge, not into a bin. Everything on this page lives in them.

Stumps

Keep old stumps

A tree stump left in the ground feeds beetle grubs for years.

Compost

Start a compost heap

A heap is warm, damp and full of food: worms, woodlice and centipedes move in by themselves.

Look

Look, then put it back

Turn a log gently, have a look, and roll it back just as it was so the damp is not lost.

Dig

Dig less

Every time soil is turned over, worm burrows are broken. A layer of compost on top lets the worms do the digging.

The recyclers

Dead wood and fallen leaves would pile up for ever without these animals. They chew it, tunnel through it and turn it back into soil.
