Hello,

Looks obvious to me, but I know all too well what that's worth...;)
Right this time?

Hello Andr?,

where have these pictures been taken? In The Netherlands? Then it looks to me more like a female Tolmerus sp. than a Machimus rusticus.

Greetings, Danny

Hi Danny,

Yep in the east of Holland (Ootmarsum). But on www.nederlandsesoorten.nl I can't find Tolmerus. So it's not supposed to be in Holland. Does Tolmerus have another name perhaps?

Hi Andr?,

yes, what we in Germany call Tolmerus is treated in other countries as Machimus. But that is not so important. What I really wanted to say is that your picture is not of a M. rusticus. After checking the Checklist of the Asilids of The Netherlands it is rather clear that your image shows a female Machimus / Tolmerus atricapillus. The other species have a different colouration of the legs and or some spines on the ventral side of the fore femora. I gues one or two of the spines would be to see on the first image. In Germany there are a few other species that would fit. And I would not be surprised if M. / T. pyragra will be caught in the Netherlands in areas with pine forests intermixed with heath in some years. Here in Eastern Lower Saxony you sometimes have to catch quite a lot of "atricapillus" to get one pyragra intermixed.

Greetings, Danny

Hi Danny,

Thanks for all your trouble. It's always difficult without a key and good images to check things. So I mainly rely on experts like you:)
