Evening All , I have found a colony of wasps in an old fence post .I think at least 2 species ,maybe 3 would like to id them please if anyone can help .
Maybe the BWARS website can help you: http://www.bwars.com/index.php?q=species_gallery/Megachilidae
Hi Florin ,
I think they're wasps not bee's .They were carrying Thrips and have narrow waists pic 3 shows this well I think .
Thanks for your help .
Oh, you are right!
What about the Crabronidae wasps? They nest in holes in wood, they are predatory.
Thanks Florin ,
going with Ectemnius Ssp and Passaloecus (maybe gracilis )
