Nomada leucophthalma female?

More fun!

I got this female on 22nd March, I have been going in circles! Maybe it could be Nomada leucophthalma? I had it's host Andrena clarkella on 19th March this year.

A male from last year which was later but might be the same species..

The only trouble is, on the German site it mentions antennal segment 3 being shorter than 4 for leucopthalma females, they measure the same. The same goes for Nomada ruficornis, and I can't see if there are thorns at the base of the hind tibia. I also had male Andrena haemorrhoa on 22nd March, and got a female on 23rd (a host to ruficornis).

The mid femora does however have long dark bristles which is mentioned on the German key for N. leucophthalma.

There is the other option of Nomada ferruginata which as mentioned on the Nomada male thread above is no longer on the RDB list, or so I found. I did have a female last year which could have been Andrena praecox which is it's host.

Andrena praecox?

I'd agree this is N. leucophthalma, in N. ruficornis females the yellow areas on the tergites are broadly interrupted by red colouration I think. The early date is also good for this species, plus you have the host present.

Thank you Tristan, that was my first thought.
