Thread subject: Diptera.info :: Rhagionidae: Chrysopilus laetus

That's a tricky male! According to the key in https://www.resea...hagionidae luteolus
males have yellow tergites with at most a narrow dark band at the front edge. In the other two species of the luteolus
) the tergites are said to have broad darker transverse bands. In your male, the posterior half of the abdomen is dark, the anterior half light. If we decide on "dark transverse bands", we are stuck, however, because now the shape and size of the clypeus is species-decisive. And you don't have a close-up of the face. So possibly laetus
or, less probable, a miscoloured luteolus
(?)... Maybe Theo has an idea!
Best wishes, Sundew
