the chrysid on the picture belongs to the genus Chrysura and it is a female specimen. My best guess is that the species is Chrysura hirsuta but I can't rule out Chrysura radians judging from this picture. Dorsal view might help more since it would be useful to see the punctuation on second tergum.

Dear Jean,
Reading you loud and clear!
These are really tricky if not impossible to do from photos. There is a Handbook produced by the Royal Entomological Society (vol6 part 5) for cuckoo-wasps. What would others say to a possible diagnosis as Elampus panzeri or a species of Omalus?

The continuing very mild late autumn weather has produced some intersting bumblebee sightings recently.
At Windsor Great Park on 4 Nov there were two B.pratorum workers on Rhododendron pachysanthum. This is a very early Rhodo. and is now in full flower and completely undamaged by any frost. On 12 Nov there were two B.pratorum workers again on the same rhodo. and also a queen. All three were collecting pollen and nectar. So there is already one nest established and a queen preparing to establish another. Incidentally this is the same Rhodo, where B.pratorum workers were seen in mid-winter in two previous winters.
On 12 Nov one queen B.hypnorum was seen warming up in the sunshine on the trunk of a large Scots Pine. A couple of minutes later another B.hypnorum queen was seen collecting pollen and nectar on Rhodo. pachysanthum. She was still foraging there 90 minutes later when we returned past the same bush. As she was collecting pollen it is likely that she will attempt to establish a nest soon. This is the first time I seen B.hypnorum in November.
There are quite a lot of B.terrestis queens about - a few collecting pollen - and a few workers. There are still a few B.pascuorum workers still around but their numbers are declining.

Thanks for the reply Andrew. I did not see more than one Ancistrocerus at one
time, and had the impression that the same wasp was making repeat visits. I will
try and mark the wasp next time. It unwrapped the caterpillar before taking it
(visible in one of the photos). On one occasion I disturbed the wasp while
photographing it. It released the caterpillar and did not retrieve it. I think
this is a typical response to interference and reduces the chance of being
parasitised.

Presumably not. Also, would more than one female wasp visit such a source of

Mating frenzy at its finest! This behaviour is indeed typically found in Europe e.g. in different Colletes species, some Andrenids as well. To witness this sort of behaviour requires the presence of massive nesting aggregation though, a rare sight.
Looking forward to the next episode of Life 2009 in a couple of days! And I recommend the companion book to the series, remarkably illustrated.

Dear Alan
I am surprised that David Attenborough implies that the male bees sting their rivals.
Their behaviour seems similar, but more extreme, than that of Colletes hederae where some males form mating balls around newly emerged females while others patrol around Ivy bushes.

I have posted three photos of Ancistrocerus sp (identified by Tim
Strudwick)taken at Weybourne North Norfolk in August. It was extracting a
caterpillar rolled up in leaves of lesser knapweed (Centaurea nigra). Before
beginning chewing the leaf-roll open the wasp paced up and down the intact
rolled leaf rapidly several times(first photo). I saw this behaviour on two
occasions on the same clump of knapweed. Can anyone inform me whether this
behaviour is a means of detecting the presence, size or orientation of the
caterpillar? It occurred to me that the same wasp was probably re-visiting the
same clump of knapweed each day. Perhaps it was assessing caterpillars at known
spots and only removing caterpillars once they had reached suitable size?
Thanks Alan
Yes it probably had been dead a while. I thought maybe D.sylvestris but the very
red clypeus confused me and I thought it might be something else. I will keep
the specimen anyway.
Thanks again

I've recorded both D. sylvestris and D. saxonica queens in the last couple of

Hi Nico,
Thanks for the quick reply. No I did not look for eggs so it's just a guess from
the position of the bee. It stayed in this position for quite a few seconds.
Maybe it was ready to lay but could find no suitable host nest, so just dumped
it in the sand?

Have you actually observed the egg in the sand after this unusual behavioural sequence? Or is it just a guess from the position of the bee?
These cuckoos generally lay eggs directly onto the brood cell of their Colletes hosts, sometimes between the layers of the cellophane-like membrane of the cells.

At the moment I can't access any of the NBN sites (from my home computer), so I
guess there's a problem at their end.

I've been using NBN this morning with no problems. i've been using if for Diptera info and checked bumblebees (B.vestalis) and all the map formats worked fine for me.
Sorry I can't help with your problem but it would appear to be at your end rather than the NBN website.

I have just received a request from Dr Steve Martin at Sheffield University who
is currently working on chemical recognition in bumblebees. If anyone can help
then please contact Steve directly at s.j.martin[@]sheffield.ac.uk
Steve writes:
Our original ms [on chemical recognition] was rejected since there was a problem
was sample size, which I have partly rectified this year. However, I am still
short of 2-3 specimens of queens of B. sylvestris, B. campestris and B.
rupestris.
Therefore, I am asking around to see if anyone has samples I can use. The best
samples would be the Dufours' gland (i.e. the sting assemblage) from frozen
queens of these species. However, the sting assemblage from dried queens will
also do. Otherwise, I can get the information from an extract from the wings of
queens. Please let me know if you have any samples I can use and we can arrange
how to move them between labs. Any help will be fully acknowledged.

Hello everyone,
This summer in Hungary I watched a wasp, (which as a novice, I believe may be
one of the Pompilidae) build several cigar shaped clay cells, around 2cm in
length,and aligned next to each other. Each on average with 8 paralysed
spiderlings, and up to 4-5 species per cell.
The pupae when full grown almost fills the cell.
Ive tried all the usual suspects for info with no success.
Any suggestions please ?
Many thanks,
John
