Hello,
can this hoverfly be identified by foto? I caught it on May 10th, 2011, on the light. Location: Germany, Rhineland-Palatinum, 53572 Unkel, River Rhine valley, dry and warm habitat.
I already posted this fly 1 1/2 years ago, with another photo, but never got an answer. Perhaps this photo is better for an identification.
Thanks in advance,
Michael

Ch. cautum should be correct. However, a good picture of the antennae is needed to compare the length of the segments (this is the first question the key
http://web.archiv...x_key.html asks). In your fly the third segment seems to equal the first and second together, which is fine for
Ch. cautum. The colouring fits well, too.
Regards, Sundew
