| Re: Ground Nesting Flies
I'm coming to trhe conclusion that they're actually ground nesting bees.
However, I don't think they're Tawny Mining Bees (Andrena fulva), as they don't have " lovely foxy red coloured hairs clothing its body", which are known to make their nests in loose soil, often in lawns. As I say, mine are greyish white with a black band across the thorax. Very attractive though, |
