‘No one knew they existed’: wild heirs of lost British honeybee found at Blenheim | Bees


Thousands of uncommon forest honeybees that look like the final wild descendants of Britain’s native honeybee inhabitants have been found within the historic woodlands of Blenheim Palace.

The newly found subspecies, or ecotype, of honeybee is smaller, furrier and darker than the honeybees found in managed beehives, and is believed to be associated to the indigenous wild honeybees that foraged the English countryside for hundreds of years. Until now, it was presumed all these bees had been utterly worn out by illness and competitors from imported species.


While feral honeybee colonies – often created by swarms of non-native bees which have left a close-by managed hive – are often found within the UK, there was no proof that self-sustaining colonies of native, tree-nesting honeybees nonetheless existed in England, and no report of the wild subspecies dwelling in Blenheim.

Filipe Salbany, a bee conservationist who found 50 colonies of the uncommon honeybees in Blenheim’s 400-acre property, stated: “These bees are quite unique in that they live in nests in very small cavities, as bees have for millions of years, and they have the ability to live with disease. They have had no treatment for the varroa mite – yet they’re not dying off.”

The varroa mite, a parasite that feeds on and assaults honeybees, arrived in Britain in 1992 and decimated the UK’s inhabitants. Salbany believes the bees he has found have advanced to outlive. “We are not seeing the deaths we would expect to see with varroa.”

Unusually, the bees swarm with a number of queens – as much as 9 in some circumstances – to make sure the colony’s survival, and have been recorded foraging for honeydew on the treetops in temperatures as little as 4C. Most bees will cease flying at 12C. “A wild bee that has adapted to the environment is called an ecotype, and this bee could be a very precious ecotype – the first wild bee that is completely adapted to living in the oak forest.”

The outcomes of DNA samples taken from the bees are anticipated inside the subsequent three to 4 weeks, however Salbany is assured it’ll present the bees are descendants of an historic native species. “I think the majority of the genetics are going to be of an old English bee, of something that was here many, many years ago.”

His preliminary evaluation of the wings of the honeybees strongly suggests they are associated to indigenous honeybees that after lived in Britain. “They are not from the imported stocks of bees that people bring in. The wings are smaller and their veins are very distinct.”

The bees’ cubital index, a way for differentiating breeds of honeybees, additionally confirmed they are “more of an indigenous bee” than the rest, he stated, however their diversifications have made them distinctive and peculiar, and they have little or no banding. “Supposedly, wild tree-nesting honeybees which can sustain themselves do not exist, so nobody knows what type of wild, self-sustaining honeybee is actually left in the UK.”

One of the nests he found was at least 200 years outdated and he estimates that the bees have been dwelling on the Blenheim property, which dates again to the center ages, for “quite a few” centuries. Unusually, they have constructed their nests in tree cavities 1 / 4 of the scale of a traditional beehive, 15 to twenty metres off the bottom, and regardless of a number of ecological surveys through the years, “nobody knew they existed”. The entrances to the nests usually have a diameter of lower than 5cm.

There are not any managed beehives on the property, which Salbany thinks has performed a crucial function within the wild bees’ survival, whereas imported bees from hives close by are prone to have been deterred from flying to Blenheim to forage by the panorama. “It’s a closed environment, in terms of bee access, because there are damp and humid valleys which form physical barriers.”

The woodlands, which Salbany describes as a paradise of biodiversity, aren’t open to guests and no planting or gardening takes place there. “There’s very little human interaction.”

The wild bees appear capable of reside in steadiness with the surroundings and in concord, not solely with one another however with wasps and bumblebees that reside within the forest. “For the 50 honeybee colonies that we have found, we probably have 500 empty sites for them to swarm into. They do not populate every single site: they’ve reached an equilibrium with their environment.”

Remarkably, he found two colonies of wild bees dwelling inside 5 metres of one another, in a single tree – proper subsequent to a wasps’ nest. “That is quite unique.” He thinks wasps don’t attempt to rob the bees as a result of the bees construct their nests very excessive up the timber and make their entrances so small: “There’s enough forage for the wasps in the forest not to go and bother the honeybees.”

As a outcome, the bees are extraordinarily relaxed and he doesn’t must put on any protecting gear round them. “I can put my hand in the nest. They are very calm.” Their honey, he stated, tastes “incredibly pure”. It may be very floral because the bees prefer to feed on dandelions, blackthorn and sunflowers. “The smell of it is just extraordinary.”

He now suspects there could also be different colonies of wild, tree-nesting bees within the UK that haven’t but been found: another excuse, he says, that “we need to protect our ancient woodlands. Because that’s where we are likely to find these bees.”

In whole, about 800,000 wild bees have been found. Salbany hopes the information can have wide-ranging implications for Britain’s giant, imported inhabitants of managed honeybees, which may “decimate the countryside” for native pollinators when they forage. “This species could be used as stock for beekeepers.”

Dr Rob Stoneman, a director at the Wildlife Trust, stated the invention of the wild bees was “extraordinary” and demonstrated the worth of the UK’s historic woodlands. “These kinds of stories give us hope and motivation to create a wilder future.”

What’s the thrill?

  • Wild honeybees are proof against the varroa mite, a lethal parasite for different bees

  • They can forage in temperatures as little as 4C

  • They’re glad to reside close to wasps and different honeybee colonies

  • They nest in timber 15 to twenty metres off the bottom

  • They reside in colonies eight to 10 occasions smaller than managed beehives

  • They have a number of queens to make sure the colony survives, and the fittest queen guidelines

  • They’re smaller, darker and furrier than imported honeybees, with smaller wings and extra distinct veins.
