Hi igor - does that mean the fly in
this thread is also
opaca?

Hi Chris,
No, the fly in the other thread is not
Empis opaca.

Hi Jan Willem - thanks for the confirmation - what are the distinguishing features that would split
opaca and
tessellata in these photos? They look very similar, except perhaps for the degree of leg coloration but I thought maybe this was due to the difference between flash & natural light.

It's not very clear in the photo's concerned, but the abdomen is dorsally dusted in
Empis tessellata and dorsally shining black in
E. opaca. The adbomen of
E. opaca is dusted at the sides though.

Empis tessellata can have extremely red legs in warmer parts of Europe, like I found in Portugal. The base of the wing in this pic looks yellowish. This could be
tessellata, also taking in mind that the thorax is very dusted.

I agree, the fly in this photo certainly looks to have a dusted thoracic dorsum - showing distinct vittae.
