Massachusetts, USA July 3, 2012 To my eye this looked exactly like Hydrophoria lancifer but on closer examination of the photo I see 1. The frons is yellow. 2. The tibiae are black. 3. There is only one pair of postsutural acrostichals instead of two. 4. M-cu crossvein is more strongly curved. It was also in an unusual place, at the edge of a field instead of in the woods. I couldn't get a lateral shot.  (Click to enlarge or view on Flickr.) |

I think H. lancifer is OK here. The all-yellow frons is just newness. It is hard to judge the colour of the tibiae at this angle - they would probably be more translucent in dorsal view. Do you have any other Hydrophoria species with black femora and a long pre-alar? |
