Berlin - July 2019 - female - 8.5mm Hello everyone, i found this attracted to light at my balcony. I have Thereva nobilitata male and female but this looks different. I try to use Haarto and Winqvist to match the frontal callus but it isn't working very well. Any suggestions? Thank you.

thorax. interesting. I am having trouble reading this because it looks like 1 dc and 2 ia. Maybe i am not seeing it correctly. Perhaps it is just nobilitata.

Definitely 2 post DC. SO no nobiliata. The tibiae look very yellow, may be the flash (?). It is not golden enough for handlirschi, which is more typical of August anyway. So I am as lost as you are. Theo |

Hello Theo and Jonas, My apologies to both of you. I am very sorry for not noticing the replies. I've been busy lately and i just didn't notice. I figure everyone is in the field this time of year. Again, very sorry. I feel bad about it.  I will add some more photos soon. I'm going to get my external drive and look through my photos. I will add photos of the legs and the haltere if i can see it. I have a specimen so i can always revisit this page. I must admit that i am definitely lost with this one. I appreciate the help very much. I will return with more photos and info... John and Nini. Naturalists not experts. |

lateral view with crop of haltere. knob seems to be grayish with a dark base. smoky i guess. maybe flash hurts the true color?

I know very little about Therevidae so i don't want to make a fool of myself but i was wondering if it could be Thereva inornata female? i don't have enough info abut Thereva so it's just a guess. Sorry if i am way off.
