Hi Matt, What features do I

Hi Matt,

What features do I need to photograph for a positive ID?

Just wondering?

I am not certain this is A. clarkella either, rather than, say A. bicolor... or even A. varians (which I know is out now).

As far as photography... the bits that one needs to look at on Andrenas for species level dets are things like the density of the punctation on the thorax, clypeus (lower face) and on T1 (1st upper abdominal plate), comparing hair colours in various parts of the face or hind legs, the form and punctation of both the front and rear of the thorax. In short, many, many microscopic characters. This is especially true of males, and the Micrandrenas as there are no bold hair colour patterns on which to rely

Thanks Stuart, It sounds like

Thanks Stuart,

It sounds like specimens need to be anethetised and studied under the microscope. I'll have to give it a try....
