UK, Suffolk, 2km from sea, grazing marshes nearby. 21.vi.2010 in sunshine on brick wall. male, orange first antennal segment, abrupt enlarged eye facets --> Hybomitra ciureai Theo, on an earlier post you mention the dusting on the scutellum as helping with the id for ciureai, could you state what to look for - its not mentioned in publications I've seen. I see female H. ciureai and distinguenda in almost equal numbers and plenty of male H. distinguenda in swarms but male ciureai are much harder to find.

-1) Yes, this is male ciureai -2) scutellum, mentioned in the dutch (= mine) key, but you don't read dutch, I guess: looking very obliquely from behind, scutellum of ciureai is completely greyish, whereas muehlfeldi and bimaculata has a black tip. Not sure if this is true in males as well. -3) Males of muehlfeldi and distinguenda are excellent and persistent hovers, males ciureai don't hover but sit on leaves on the look-out. You can find males ciureai at warmer evenings (if you have any in UK) at light Theo |
