Hello! I found this beautiful Thereva today near the forest here in Ostwestfalen/Germany. Can the species be determined from the photos? Thanks in advance!

Hi Juergen I wonder whether this might be a female Thereva handlirschi. (Not a species I'm familiar with, but the description seems to fit.) This is only a suggestion - it would be best to wait until someone familiar with the central European species can confirm this before adding it, even as a temporary name. Tony ---------- Tony Irwin |

Hi Juergen and Tony, The species looks very yellow indeed, which makes Tony's guess a good one. However, I can see only 1 pair of dorsocentral bristles on the thorax. If that is correct, the picture cannot represent handlirschi, since this species has 2 pairs of DC before scutellum. Maybe Juergen can check on an original at higher resolution ? Theo Zeegers |

Hello, Tony and Theo! Thanks for your replies! Zeegers wrote: since this species has 2 pairs of DC before scutellum. Maybe Juergen can check on an original at higher resolution ? Below two uncompressed extracts from the photos. But I am not sure, whether they show that detail better...

I can still see only one pair of DC. But it is difficult to see, so I don't have a final opinion in this matter. Sometimes we just cannot ID from fotos ! Theo |
