SW London on bamboo, quite small.

Afternoon Toby,

It's a Sphecid Wasp - more photos needed for genus, please! I don't have anything similar in my collection (=1 sub-marginal with pointed discoidal).

Take care,

Jason

I keep coming back to this one! It's always a lot easier with specimens - I think I interpreted the sub-marginals incorrectly given the angle of the wing. I think there may be three - and this could be a Psen species or similar on account of the constricted first gastral tergum.

I'd certainly be interested in other experienced views on this.

one other view, wasp was very flexible:

Is that the only other one? Very interesting, either way.

no more pics, will keep an eye on the area (grounds of work place).

Thanks, and if I collect a Psen or relative I'll give this thread another look-in.

Afternoon Tobes,

I collected one today, and have it as Psen/Psenulus sp. - I'll know more when it's set. I'll give yours some more though then - probably Thursday.
