Short-fringed Mining Bee - Andrena dorsata

The short-fringed mining bee - Andrena dorsata, is a lovely bee to look out for from spring onwards, through to autumn, since this bee species is bivoltine, having two generations (nest cycles) per year.

About The Short-fringed Mining Bee - Andrena dorsata

This bee is typically a little smaller than a honey bee, measuring less than a centimetre in length (up to 8mm for females, with males a little smaller).

Females have reddish ginger hair on the thorax (upper body).  The dark abdomen features distinctive pale hairs around the edges, although these fringes of hair don't meet in the middle to give an appearance of full 'stripes'.

Males are more slender than females, with longer, pale hairs on the face.

In Field Guide to Bees Of Great Britain And Ireland, Falknotes that Andrena species have "more extensive pollen-collecting apparatus than most other bees".

This includes not only most parts of the hind leg, but also hairs arranged in a type of pollen basket on the propodeum, which Falk describes as the rear section of the thorax.

Below is a lovely image from an old journal from the year 1899:  Cambridge Natural History (V. 6).

It compares different hairs taken from the bodies of bees and specifically includes a hair from the thorax of Andrena dorsata - the plumose hair labelled 'D'.  It appears perfectly designed to trap pollen - see my page about bees and sticky hair

However, bees of different species may have a variety of hair types on their bodies (simple, spiral or plumose), and for example, plumose hairs have been found to occur on male bees and parasitic bee species that do not carry pollen2.

Short-fringed mining bees belong in the Andrena genus, and are part of the Andrenidae bee family.

As with all other members of the Andrenidae, this bee species belongs in the short-tongued category.

Habitat and foraging preferences

Brownfield sites, coastal and heathlands as well as gardens may provide foraging and nesting opportunities for Andrena dorsata.

Look out for the first generation of short-fringed mining bees on spring flowering plants and shrubs, including willows, gorse and dandelions.

Later, as the next generation emerges, look to brambles, ragworts, daisies, thistles and heathers.
