Bilberry Mining Bee (Andrena lapponica)

Andrena lapponica (Zetterstedt, 1838) · family Andrenidae


The bilberry mining bee is an upland, ground-nesting solitary bee tied to the moors, heaths and open woods where bilberry grows. Where many of Britain's mining bees belong to lowland gardens and verges, this one is a creature of the hills, emerging in spring to work the nodding pink flowers of bilberry on the moorland edge. Its scientific name, lapponica, means of Lapland and points to its cool, northern character. See where it sits among Britain's bees on the UK Native Bee Species Map, or among the world's bees in the World Bee Atlas.

How to identify a bilberry mining bee

The bilberry mining bee is a medium Andrena, roughly 10 to 12 mm long. The female has a black-haired face, a warm reddish-brown pile of hair over the top of the thorax, and a blackish, distinctly shining abdomen fringed with long pale hairs, most obvious on the first segment.[2] It closely resembles the heath-loving Andrena varians, but the pale hairs on the first abdominal segment are less dense, the abdomen is shinier and the overall build is a little broader.[2] Males belong to a group with long jaws bearing a small triangular projection near the base, and they always have dark hind feet, which helps separate them from close relatives.[2]

A bee of the uplands

More than its markings, it is location that identifies this bee. The bilberry mining bee is a specialist of upland and northern country: moorland, upland heath, open birch and pine woods, and the bilberry-clad edges of bogs.[1][5] A medium, foxy-thoraxed mining bee working bilberry flowers on a Welsh, Pennine or Highland hillside in spring is very likely this species, simply because few other mining bees share that ground at that time.

A bee that follows the bilberry

As its name suggests, the bilberry mining bee is closely linked to bilberry (Vaccinium myrtillus) and its relative cowberry, whose pink, bell-shaped flowers it works busily in spring.[1] It is not strictly tied to them, and also visits willow, blackthorn, gorse, dog-violet, thyme and other moorland and woodland-edge flowers, but bilberry is its signature plant.[1] Adults fly from April to July, peaking as the bilberry comes into bloom, in a single generation each year.[2] Like all mining bees it is solitary: each female digs and stocks her own burrow in well-drained ground among the heath, with no queen and no workers.

A foxy-thoraxed mining bee busy on bilberry flowers high on a spring hillside is almost certainly this upland specialist.

Its cuckoo: the bilberry nomad bee

Like other mining bees, the bilberry mining bee has its own dedicated cuckoo. Its nests are parasitised by the bilberry nomad bee (Nomada glabella), a wasp-like cuckoo bee that was for a long time treated as a form of Panzer's nomad bee (Nomada panzeri).[1][3] Recent work combining DNA barcoding and close study of structure confirmed the bilberry nomad as a distinct species, widespread and long established in bilberry-rich districts of Britain and often flying alongside true Panzer's nomad bee.[3] The female cuckoo enters the mining bee's burrow and lays in a provisioned cell, where her grub destroys the host egg and eats the stored food. You can meet another British cuckoo bee in our guide to the painted nomad bee.

New

The bilberry mining bee's cuckoo, the bilberry nomad bee, was confirmed as a species in its own right only recently, through DNA and morphology, having long passed as a form of Panzer's nomad bee.[3]

Where and when you will see it

The bilberry mining bee follows its food plant, so it is most frequent in the bilberry-rich uplands of northern and western Britain, from Wales and the Pennines to the Scottish Highlands, with more scattered records on southern heaths where bilberry persists.[4][5] It is best looked for on warm spring days from April onwards, low over open heath and around flowering bilberry, where the female works the bells and the smaller, plainer male patrols for mates.[2] It is a local species overall, tied to its habitat, but can be frequent where bilberry covers the ground, and across its wide northern range in Europe it is not considered threatened.[6]

Apr

One generation a year, on the wing from April to July and peaking with the spring bilberry bloom on upland heaths and moors.[2]

Why the bilberry mining bee matters

Bilberry is a keystone plant of British moorland, feeding birds, mammals and people, and the bilberry mining bee is one of its most faithful spring pollinators.[1] A healthy population is a sign of unbroken, flowering upland heath, the same habitat that supports red grouse, mountain plants and a wider community of specialist insects. Because it depends on extensive bilberry and open, well-drained ground to nest in, conserving and restoring upland heath, and resisting its loss to overgrazing, drainage and afforestation, is the surest way to keep this hill bee and its dedicated cuckoo in the landscape.

Frequently asked questions

What is a bilberry mining bee?
It is a medium-sized solitary mining bee, Andrena lapponica, that lives in upland and northern Britain and is closely associated with bilberry. Each female nests alone in the ground, and the bee flies in spring to work bilberry and other heath flowers.
Why is it called the bilberry mining bee?
For its strong link to bilberry (Vaccinium myrtillus), whose spring flowers it works heavily. Its scientific name, lapponica, means of Lapland, reflecting the cool, northern uplands where it is most at home.
How do I identify Andrena lapponica?
Look for a medium mining bee about 10 to 12 mm long with a reddish-brown furry thorax, a black-haired face and a shining dark abdomen with long pale hairs on the first segment. Habitat is the surest clue: a foxy mining bee on bilberry flowers on an upland heath in spring is very likely this species.
When are bilberry mining bees active?
They fly in a single generation from April to July, peaking as bilberry comes into bloom in spring on moors and upland heaths.
Where do bilberry mining bees live?
In bilberry-rich uplands, mainly across northern and western Britain, from Wales and the Pennines to the Scottish Highlands, with scattered records on southern heaths where bilberry grows. It is a local species, tied to its habitat.
Do bilberry mining bees sting?
They are very docile and almost never sting. As solitary bees they have no colony to defend and the sting is weak, so they are harmless to walkers, children and pets on the moor.
What is the bilberry nomad bee?
It is the cuckoo bee that parasitises the bilberry mining bee, Nomada glabella. Long treated as a form of Panzer's nomad bee, it was recently confirmed as a distinct species through DNA and structural study, and is widespread in bilberry districts.
Does the bilberry mining bee make honey?
No. Each female stores only enough pollen and nectar for her own larvae, never a harvestable surplus. Only the honeybee makes honey in any quantity. Compare the bee families in the World Bee Atlas.
