Habitat and Distribution
Diet
- Larvae feed on decaying wood under the ground. Adults can’t feed on solid food – they rely on the fat reserves built up whilst developing as a larva. They can use their feathery tongue to drink from sap runs and fallen soft fruit.
Breeding
- Males are often seen flying around at dusk searching for a mate. They will wrestle or fight other males using their enlarged antler-like jaws. Although they can fly, female beetles are most often seen walking around on the ground. Once they’ve mated, females return to the spot where they emerged, if there is enough rotting wood to feed their young, and dig down into the soil to lay the…
Predators
- Predators such as cats, foxes, crows, kestrels and others tend to strike at the most vulnerable stage in the beetle’s life cycle, when adults are seeking to mate and lay eggs. Though this is largely natural predation, the rise in the numbers of magpies and carrion crows in the last decade may be having an impact on stag beetle populations.
Threats
- Humans are, unfortunately, a direct threat to stag beetles. Adult beetles are attracted to the warm surfaces of tarmac and pavements, which makes them particularly vulnerable to being crushed by traffic or feet. Stag beetles have a fearsome appearance and sometimes people kill them because they look ‘dangerous’. Changes in weather patterns are also...
Status and Conservation
- Stag beetles are legally protected from sale in the UK. They are also classed as a ‘priority species’, listed on Schedule 5 of the Wildlife and Countryside Act 1981. If stag beetles or their larvae are known or thought to be present at a site where an application for planning has been submitted, and are likely to be disturbed or destroyed whilst work is carried out at the site, it’s recommende…
How You Can Help!
- Please help us protect this unique British species by telling us about where they live near you and by making your garden stag beetle friendly. Thank you.
