Andrena nitida
- The Grey-patched mining bee

All kinds of bees love dandelions, and among the fans of this flower, we can include the Grey-patched mining bee, Andrena nitida.

In Britain, this species can be seen from late March onwards through to July.  I took these photographs of the female specimen below in early April, which is peak season for this species through to May.  

About Andrena nitida

Females measure up to 12mm, males are a little smaller.  They are slightly larger than a honey bee.  This species is univoltine (having one generation, and therefore, one flight period in a year).

They are found in a variety of habitats.  The photographs on this page were taken on a local old brownfield site close to where I live.

Nest sites

It likes to nest in flat or sloping turf, and according toand according to Stephen Falk’s bees of Great Britain and Ireland, nests may also occur in formal lawns as well as sheep-grazed hillsides.

Nest burrows are scattered rather than in aggregations.

In addition to dandelions, it may be seen foraging on hawthorn, blackthorn, gorse, raspberry, dead nettles, speedwell, willow, and cherries.

If you want to catch sight of this bee species, check spring flowering blossoms of flowers and shrubs.
