Thread subject: Diptera.info :: Asilid with strong blond hairs in Fontainebleau forest

Hello,

www.galerie-insecte.org/galerie/image/dos166/big/5db22416.jpg

Pierre Duhem : France : Fontainebleau : 77300 : 22/06/2016
Altitude : 90 m - Taille : 15-16 mm
Réf. : 166293

It seems that Asilids rarely open their wings to show the tergits. I'm rather clueless in front of this one, with its strong blond hairs between tergits.

Can somebody give me a pointer?
Thanks in advance.

This should be a male Dysmachus sp. But a lateral view would be most welcome to confirm...

For Fontainebleau it must be Dysmachus trigonus.

Thanks to both of you.
Sadly, I don't have any othr picture.

One of your remarks is typical for a group of Dysmachus species, these have trouble in closing their wings because of the strong bristles on their abdomen. : ) (or so it seems) The species are D. trigonus, D. cristatus and D. dasynotus. From NW Europe only trigonus is known and very common. The other two species are bound to mediterranean habitats. By default this is trigonus.
