Parasitoid wasp and mud dauber

Trypoxylon sp


Small Brachymeria wasp, about 3mm and fine wasp of Crabronidae measuring about 1cm approximately.


Nest located on the wall of my house.


I registered a Brachymeria prowling Crabronidae nests, the Brachymeria stayed a long time on the nest, bothering the Crabronidae that worked in the sealing of the nest carrying small mud balls. I'm intrigued, could this Brachymeria be a parasitoid for Crabronidae's mud nests? Please, if anyone has information about this event, I'm very grateful.

Hi Sckel

There are a couple of references to Brachymeria sp. (in one case B. villosa) parasitising Trypoxylon sp. - and in Brazil!

In case the links don't come through - just google "Peruquetti Brachymeria Trypoxylon"

Hope you are well - sorry I haven't been very active for a while.
