Dear Mike,
I was able to access the file simply by double clicking on it so I guess everybody can as well. Would you have a drawing of an Anthomyiid wing, I am trying to learn to separate scathophagids on the basis of wing venation. Jan Maca tried to help when he was here, but I didn't write anything down and now I forget which was which, on anal vein reaching the wing margin or not reaching it. On the flies I am comparing there are 3 veins not touched by the costa, numbering 1, 2, and 3 from the wing tip to the anal lobe. 1 and 2 are straight 3 is usually curved to some extent). No. 1 always reaches or gets very close to the wing margin and sometimes seems to project deyond it as a small spine. In some 2 fades out in the second half, but can be seen to reach the margin, in others it is much fainter, or apparently absent. As far as I can see 3 never reaches the margin, but it does get closer in some than others.

Any other tips on separating the two groups, linked in my mind by the absence of serious bends in the major veins, and bare or basically bare antennae will be greatfully received.

Hoping you, or somebody else, can help me make sense of this.:)

Thanks,

Gordon
