Hi, Yesterday I met this Tachinid male on Yarrow inflorescences. With the key http://www.tachin...chweb.aspx, using different characters, I always arrived at Bithia, a genus new to me. Proceeding with the Bithia key in https://tachinida...igures.pdf, I found already the first couplet applicable: "r4+5 with bristlets reaching much further than r-m. r1 and cu1 almost always with bristlets". However, in this case the scutellum should have a short lateral bristle, which I cannot see. Nevertheless the wing bristlets point out to B. spreta. Can this species be confirmed, or did I misapply the genus? Thanks for comments! The location was the small town of Malmsheim in Baden-Wuerttemberg. |

Wing details. In the middle picture I marked the bristlets' extension on r4+5. The bristlets on r1 and cu1 are also visible. |

Looks totally OK to me. I never use this “lateral scutellar” thing, but now you mention it, I see a hairlike bristle present. Theo |
