I have posted information on this bee before , I hadn’t seen one until the other week now I’m finding them everywhere. I was not expecting to see one here though as it is on the Fen side of Cambridge which is not the chalky grass lands they like , its more old railway embankment surrounded by miles of either rapeseed, broadbean or wheat fields. Anyway its a good sign and another record for the distribution map.
Andrena scotica is a mining bee. These are very hairy bees and at 10 to 14 mm Andrena scotica is one of the larger species, the male being slightly smaller than the female. They are slimmer in appearance than bumblebees.
They especially enjoy firm sandy soils with no overgrowing plants to smother the nest, for this reason they are often found near to pathways.
When to see it
Mid March to late June – peaking late April and May.
Females share a common entry during nesting. Underground however each female takes care of her own chamber. Using the same entrance without being a real structured community is called communal. Because many chambers share one exit, fresh animals meet each other in this exit while trying to get out for the first time in spring. Males try to mate immediately, so in many cases the females have been fertilised even before seeing daylight.
One of the most common Andrena species, with most British records coming from southern, central and north-eastern England.
A mating pair of Andrena haemorrhoa .. When he just wont take no for an answer and all those legs just get in the way.
Length 8 to 11 mm. The thorax is foxy brown on top; the abdomen is black, except for the rear end, which is foxy brown again. The male is much smaller than the female and its hairs are much lighter colour, tending to grey or even white.
Around potential nesting sites such as gardens, playgrounds, sports fields, paths and the sides of roads.
When to see it
March to June.
Females are often seen nesting alone, but groups of females do occur, even though these groups are never very big.
