I think the first photo is of Cerceris rybyensis by comparison with photos on http://www.bioimages.org.uk/html/r156911.htm but then the 2nd and 3rd photo - although taken only a couple of minutes later on the same shrub the 3rd photo is a different insect but may be the same species. The 4th photo was taken at the same location 31/7/2010 could anyone tell me if it this is also a Cerceris rybyensis (I didn't even realise until I put the photo on the computer that it has captured a small bee, common prey of Cerceris rybyensis I think).
Is there much difference in the markings between individuals or male/female?
Thanks in advance
Nick
