Thread subject: Diptera.info :: Calliphoridae. -> Pollenia cf rudis or hungarica - female

A female Pollenia of the rudis group. I've only examined and identified 7 different Pollenia specimens. I suspect this to be Pollenia rudis but it is very difficult to separate rudis from hungarica via photo. Further, hungarica is one of the species that I have not examined yet. The black vestiture or lack of golden vestiture on the femora and the ventral abdomen lead to Pollenia rudis versus hungarica. The eye in profile is much higher than the gena of the aptly named angustigena so I am comfortable suggesting Pollenia cf rudis.

Some problems for me is that the genal groove appears to be more well defined than what I've seen for P. rudis. Also, I cannot tell if there are three-to-four marginal scutellar bristles. Some of the bristles could be missing. I am not a teacher (nor will that ever happen), so I am not able to convey my knowledge very well. I see several reasons why this should be P. rudis. If you are not comfortable with a cf, then simply rudis group.

I hope that you have a Pleasant Day.
