Stag Beetles

Spectacular stag beetles are one of our largest beetles. Sadly their numbers are declining across Europe and they are now extinct in some countries. In the southern parts of the UK they are doing much better but they still need our help.

You will often see stag beetles flying around on warm evenings in May and June.  Gardeners often dig up the large, white larvae (grubs). Stag beetles are big – up to 8cm long. Only one UK beetle is bigger and that’s a water beetle. They have an amazing life cycle which lasts several years. As a result this makes them vulnerable to predators and habitat destruction. Please go to the relevant page below to learn more about stag beetles. You can record a sighting or find out how to help them in your garden, park or local green space.
