Stag Beetles

Home // Campaigns // Stag Beetles

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.
