Stag Beetles: How Uncommon Are They?

Stag beetles are a species of insect belonging to the family Lucanidae, encompassing over a thousand species worldwide. They are relatively widespread in southern England and live in the Severn valley and coastal areas of the southwest. In the UK, they are legally protected from sale and are classified as a Priority Species for Conservation under Schedule 5 of the Wildlife and Countryside Act 1981. They have undergone a decline across Europe, with females preferring light soils and males lacking the enlarged antler-like jaws of male stag beetles.

Lesser stag beetles range in size from about 2-4cm and are matt black in color. Males lack the enlarged antler-like jaws of male stag beetles, but the differences are less noticeable than in the stag beetle. Lesser stags are uniformly smooth-skinned, have orange heads and legs, and brown jaws. They are nearly always found below ground and can be as deep as half a meter down.

Stag beetles are Red listed in many European countries and have gone extinct in Denmark and Latvia. They have been studied for nearly 20 years, with the help of the public and partner organizations. The single most important action to help stag beetles is to keep stumps in place when trees or woody shrubs die or are cut down, providing essential decaying wood underground for stag beetles to eat for years to come.

Stag beetles are rare and threatened throughout northern Europe, with populations in the Thames Valley being some of the largest in the world. London is a particular stronghold for these beautiful and interesting creatures. Some Australian Stag Beetles are very rare, so it is important to leave them to breed in their chosen habitat.

To help stag beetles, record your sightings as part of the Great Stag Hunt and plant a few local deciduous trees in your garden. The loss of its woodland habitat means that the stag beetle is now a nationally scarce species.

What Happens If A Stag Beetle Bites You?

Blister beetles, longhorned beetles, and stag beetles can occasionally bite humans. Blister beetles, commonly found in gardens, release chemicals that cause painful sores. Longhorned beetles, identifiable by their long antennae, may also bite. The sting from these beetles, including stag beetles, can heal within a few days without lasting harm. Stag beetles, particularly the Giant Stag Beetle known for its massive pincers, have a reputation that can seem intimidating.

Controlling stag beetles is challenging due to their ability to fly and burrow. The best prevention against bites is to deter them from entering your yard. If bitten, it's advised to wash the area with soap and water and apply a cold compress for relief. While male stag beetles possess large mandibles resembling antlers and may nip if threatened, they are typically not dangerous to humans. Their bites are unlikely to cause serious harm—usually a minor discomfort that can occur if mishandled.

It’s important to note that stag beetles are harmless and play a vital role in the ecosystem. While they can bite if provoked, they will generally avoid interaction if left undisturbed. If encountering one, it's best to leave it alone or gently relocate it if necessary. Overall, beetle bites are rare and mostly non-threatening unless an allergic reaction occurs. Stag beetles, particularly the massive Giant Stag Beetle from Southeast Asia, exemplify this fascinating but safe group of insects.

What Is A Stag Beetle?

Lucanus cervus, known as the stag beetle, is the largest terrestrial insect in Europe, particularly notable in the UK. The species name originates from Pliny the Elder's reference to Nigidius, who named it after the Italian region of Lucania, where stag beetles were used as amulets. Stag beetles belong to the family Lucanidae and are distinguished by their large mandibles that resemble deer antlers; typically, males possess longer jaws than females. Despite their intimidating appearance, they are harmless to humans and are sometimes referred to as pinching bugs.

Primarily residing in southern and central Europe, including parks in London, stag beetles can fly and exhibit combat behavior using their jaws. They thrive in woodland and urban areas that feature decaying wood, which is crucial for their larvae, as they feed on rotting logs.

With around 1, 200 species identified in four subfamilies, stag beetles can grow to over 12 cm. In the UK, the common stag beetle measures up to 7. 5 cm and displays distinctive antler-like jaws, making them easy to identify. Their life cycle involves a lengthy larval stage predominantly lived underground. Conservation awareness is vital, as stag beetles are rare and threatened, reliant on woodlands for survival. Foraging on decaying wood forms a crucial part of their diet, contributing to their ecological role.

How Long Do Stag Beetles Live?

Stag beetles, scientifically known as Lucanus cervus, have an average lifespan of three to seven years, primarily spent in the larval stage, where they thrive underground, forming tunnels in decaying wood. Females can lay up to 30 eggs in decomposing wood or surrounding soil, while larvae spend almost six years developing before emerging as adults. Interestingly, adult males live only for a few days to a few weeks, as their main purpose is to mate and die shortly after. Healthy female stag beetles have a slightly longer life, lasting around ten days to a couple of months, with most adults typically dying by the end of August.

Stag beetles belong to the Lucanidae family, which includes about 1, 200 species and can span a range in size, from 3. 5 cm to over 12 cm in some instances. Their diet mainly consists of decaying wood and tree sap, and they face predation from bats, birds, and insect-eating mammals. Their habitat preference includes woodlands, particularly oak woods, as well as parks and gardens in southern and central Europe, with a significant presence in southern Britain.

The larval stage can take about 30 days for eggs to hatch, with larvae consuming rotting wood and roots until they metamorphose into adults. Unlike adults, larvae mature slowly, taking roughly three to five years, while adult stag beetles remain active primarily between May and August. Although they mellow into adulthood in warmer weather, their short life cycle as adults is designed around reproduction, making them vulnerable to challenges like habitat isolation due to their limited movement.

Overall, stag beetles illustrate a fascinating life cycle that emphasizes the significance of decaying wood for their development, alongside the unique adaptations they exhibit in their brief adult existence.

What Is The Rarest Kind Of Beetle?

The Salt Creek tiger beetle (Cicindela nevadica lincolniana) ranks among the rarest insects globally, inhabiting a highly restricted range in the United States. It was designated as an Endangered Species under the U. S. Endangered Species Act in 2005, with its survival reliant on ongoing conservation efforts. This remarkable beetle is often highlighted alongside other endangered insects, such as the Five-horned Rhinoceros Beetle (Eupatorus gracilicornis), which is rare due to its desirability among collectors.

Another noteworthy species is the Khonkus beetle, critically endangered and found solely in Madagascar's forests, as well as the impressive Goliathus goliatus, which inhabits Africa's tropical rainforests and can reach lengths up to 10 inches.

Among the world's insects, the tree Lobster, or the Lord Howe Island stick insect, was once deemed extinct by 1920, only to be rediscovered in 2001. The American burying beetle (Nicrophorus americanus) and the elusive American Bembidion brownorum, last seen in 1966, also exemplify rare species. Notable discoveries include two new populations of the Blue Ground Beetle (Carabus intricatus) in Devon, emphasizing the ongoing need for awareness and conservation of rare beetles across North America and beyond.

Do Stag Beetles Recolonise Sites In London?

Stag beetles face significant challenges in recolonising habitats even after restoration efforts, highlighting the importance of their remaining homes. London is home to three internationally protected sites for stag beetles: Epping Forest, Richmond Park, and Wimbledon and Putney Commons, all designated as European Special Areas for Conservation. Despite their protected status, stag beetle sightings in north and east London remain notably low. Since the 1940s, stag beetle populations have declined, contracting their distribution across southern England.

The stag beetle, known for its impressive jaws, is more commonly found in woods, parks, and gardens in South East England during summer. Despite recent records from many London boroughs, they are most prevalent in the south and west of the city. Conservationists stress that London holds significant stag beetle populations, with over 3, 000 records accounted for in the 1998 national survey. Key boroughs with higher sightings include Croydon, Lewisham, and Bromley.

Their natural habitats include woodlands, hedgerows, and urban parks, but successful recolonisation is limited by their specific habitat needs, such as underground dead wood. To aid conservation efforts, researchers encourage the public to report stag beetle sightings across London.

Is The Stag Beetle Endangered?

Males of the Stag Beetle species possess large pincers for combat during mating season, while females have smaller pincers. Their exoskeleton offers protection against climate changes, but they are facing endangerment due to habitat loss from urbanization and logging. The Stag Beetle, particularly the European stag beetle (Lucanus cervus), is one of the largest beetles in Europe, known for its notable antler-like mandibles. Its larvae thrive in decaying wood, which is increasingly rare. Historical superstitions labeled the stag beetle as "devil's imp," leading to their persecution, as noted by a writer in Notes and Queries. Presently, conservation efforts are crucial since these beetles are viewed as a priority species in the UK, despite recent stabilization in numbers after significant declines. They are protected under the Wildlife and Countryside Act 1981 and are listed as a priority for the London Biodiversity Action Plan. However, they remain endangered in many regions, with populations shrinking due to habitat loss. Stag beetles were once common, especially in Southern England, but face threats from human activity and urban environments. Although sightings can still be recorded to aid in conservation, the reality is that these remarkable creatures are rare and declining across Europe, already extinct in some nations like Denmark and Latvia.
