    Chocolate Mining Bee (Andrena Scotica)

    Two days ago I spotted Marsham’s Nomad Bee, which preys upon mining bees, especially the Chocolate Mining Bee.  Then yesterday, I noticed this bee in Vole County.  It is, in fact, the chocolate mining bee and is usually found in sandy soils, parks, gardens and woodland, between mid-March to mid-June.  Females nest singly but may share a burrow entrance.  They forage on many different spring-blossoming shrubs, trees and low-growing flowers including buttercups and willows. 

    The larvae of Marsham’s nomad bee attach themselves to bees when they land on flowers and are then flown right into the mining bee’s cell where the consume the contents, including the eggs of the mining bee.

    Yesterday, I spotted the bumblebee plumehorn, which I thought was an actual bee, but I also noticed a ‘funny wasp’.  I could see it didn’t look quite right, but I wasn’t sure why.  For a start, the stripes had no dots, but were regular (apart from the first two being split with a black line, which defines it as the Marsham’s Nomad Bee).  The legs were brownish, not yellow, and the thick antennae red-brown, rather than black.  And although the abdomen looked the right shape, the waist was too long and the wings covered the abdomen, rather than lying down each side.  Interestingly, this is not a hoverfly, but a bee.  Nomad bees are, nevertheless, parasites, and also known as cuckoo bees.  This bee can be seen from April to June and lays its eggs in the nests of mining bees.

    One final point to note is that although it looks menacing and waspish, it doesn’t sting humans.  In fact, I was pleased to learn that no solitary bees sting humans, as they do not have a hive and stores of honey to defend and are therefore less aggressive.
