Hello gardensafarinl,

U pupae of a Bombyliidae. Seeing the late date I wonder if this might be a Villa hottentotta or just a late Bombylius. I know in our city the options are Bombylius major or B. discolor.
You add the sighting to waarneming.nl?

Kind regards,

Ectemnius

Thank you very much!
Yes, the sighting is in waarneming.nl, where the pupa of a Asilidae was suggested, changed into a Exuviae: https://waarneming.nl/waarneming/view/163148985

Villa hottentotta has never been seen in my garden, for what it is worth.
Spotted in my garden over the years are only B. major and B. venosus.

I believe this belongs to a member of Asilidae, not Bombyliidae.

The presence of 2 mesothoracic spines is characteristic of Asilidae and never found in Bombyliidae. Furthermore, Hull 1973 notes that Bombyliidae never have more than 2 posterior antennal processes; this one has 3.
