There are many of these bees hanging around the entrance to Andrena nests - photos to come
No interactions present.
Do you know which Andrena bees were they associating with?
there are 6 or more species of Andrena in the garden
the most common is Andrena cineraria, and I saw this bee go down a cineraria burrow - but nearby are also quite a few A carantonica (?), and this nomad species as well as N flava investigated entrances to nests of both species. However, I haven't seen this species enter A carantonica nests, nor have I seen N flava enter A cineraria nests. Oh and er spelling mistake with the name - N lathburiana
I believe N.lathburiana specifically targets A.cineraria, so there's a good chance of it being that species. Especially as this individual has the distinctive missing wing, so can be easily tracked.
I'm still learning about such things, though. No doubt someone with greater knowledge will shed more light on this.
