A national search for the UK's largest land beetle begins in late May, involving British families, nature enthusiasts, and friends.

Wildlife charity People's Trust for Endangered Species (PTES) has spearheaded the annual Great Stag Hunt survey for more than two decades.

Adult stag beetles, distinguishable by their antler-like jaws and often spotted on sunlit structures, will surface from the ground in the early summer.

During this time, PTES is encouraging volunteers to record any sightings online.

David Wembridge, mammal surveys coordinator at PTES said: "We need volunteers to become part of a national effort to monitor these amazing animals.

"The data collected by the Great Stag Hunt gives an insight into where stag beetles live and what the impact of climate change might be."

Although stag beetles, native to Britain's cities, suburbs, parks, and woodland edges, are a priority species, their habitat has diminished due to the removal of deadwood and tree stumps.

Because they are attracted to warm pavements, they are also prone to being crushed by traffic and humans.

Despite these challenges, PTES has diligently coordinated volunteer efforts since 1998 to gather crucial data and develop new habitats.

A majority of stag beetles have been observed in southern England, with 2,269 beetles recorded in Hampshire, 2,154 in Greater London, and 1,355 in Surrey during last year's survey.

Last year alone, the efforts of thousands of volunteers resulted in more than 14,000 stag beetle sightings, including 200 larvae.

Rare sightings have been reported in North Ayrshire, Scotland, and Cumbria.

Therefore, PTES continues to encourage people in these regions to track local stag beetle populations.

Anyone with garden space can create a half-buried log pile, which PTES has noted is the perfect habitat for stag beetles and other numerous species.

The charity also offers an interactive 'Map Your Log Pile' feature, encouraging the public to enter their log pile locations.
