This species looks very extraordinarily in my region. It should be Asilinae, but sits quite differently - in the beginning I thought it was not a robberfly. Can anybody help to identify it?

Slovakia, Banská Bystrica, mountain meadow, 650 m.a.s.l., 6 July 2023.

Thank you in advance
Matej

Hi Matej,

Check Didysmachus picipes female, the ovipositor is quite remarkable.

Best, Jonne

Thank you, Jonne

Yes, you are probably close. I should feel ashamed as Didysmachus picipes is the most common robberfly species in my region. I let myself to be misled byt the overall impression.

However, there is one difference between D. picipes and this specimen - conspicuous yellow bristles on the front tibia. As for ovipositor, there are black bristles on the ventral side, which I cannot see in my pictures f D. picipes females. Maybe some Dysmachus? There are eleven species of them in the Slovak checklist.
