Stag Beetle (male)

Scientific name:  Lucanus cervus

Size:  Male Stag Beetles grow to about 90mm in length, including the antlers, and female Stag Beetles grow to around 60mm

Distribution:  Found mainly in the south and south east of England.  Hot spots for the Stag Beetle are Dorset, Surrey, Greater London (especially Bromley, Croydon and Lewisham), Essex, Kent, Berkshire, Bucks, Hampshire, Herts, Suffolk, West Sussex and Oxfordshire

Months seen:  Seen flying at dusk from May to August

Life span:  The larvae live in soil for 5 to 6 years.  The adult beetles live for up to 8 weeks.

Habitat:  Woodlands, parks and gardens

Food:  The larvae eat rotting wood.  The adults only drink tree sap

Special features:  Stag Beetles are the largest beetles found in the U.K. and they're now quite rare.  The decline of our Stag Beetles is mainly as a result of habitat loss.  Some are killed by cars on roads, and since they spend such a long time in the larval stage they are also vulnerable to predation.

The most noticeable features of the male Stag Beetles are the large antler-like pincers, which give the beetle its name.  The pincers are used during the mating season to fight with other males over territory.  Each male tries to grab his opponent between his pincers, and then throw him.

The fully grown male stag beetles can normally be seen flying at dusk between May and August.  They look quite unstable in flight, and their wings make a loud buzzing sound.  The warmer temperatures of late spring encourage them to look for a mate.  They will drink tree sap, but do not eat, and will not grow at all.  After mating the male Stag Beetles die.

The females can be recognised by the much smaller pincers.  Although both the male and female Stag Beetles can give you a pinch, they are quite harmless.  Females lay their eggs in, or near, rotten wood, and then die.

The larvae (grubs) which hatch from the eggs, have cream coloured bodies with an orange head and orange legs.  They live and feed in rotting wood for up to six years.

When fully grown, the larvae leave the wood to pupate in soil.  This occurs in the summer, while the weather is still warm.  The fully grown beetle remains in this state until the following spring when it emerges as an adult beetle.
