These pictures were taken (with a strong risk of tumbling down into the water - luckily enough I put my gum-boots on) near the railroad's embankment at the edge of a small pond where blocks of a cut down aspen tree were lying. I think the first species was scared away from vegetation by my noisy approach to sit either on these tree blocks or small branches that remained on them. Rather big, 4-5mm, moving slow, and very dark in appearance (I just had to ajust levels in order to reveal more details). Maybe a Notiphila?

The second species was smaller, around 3mm. I saw mating flies, too, but unlike Nikita  wasn't able to capture the process  , it was so quick. Maybe a Hydrellia sp.?

I agree with Nikita - the first one is Notiphila (s.g. Dichaeta) caudata female - the males have very long strong bristles on the end of the abdomen. The other is a Notiphila, but I wouldn't like to say which species without examining the genitalia. Tony ---------- Tony Irwin |
