Your right, it is Eutanyacra picta, not uncommon. There are quite a number of records on irecord. Not certain if NBN has the resources to keep up with the mapping of ichneumonid records

Its a Ctenopelmatinae ichneumonid. I think its Protarchus testatorius or possbly P. melanurus, their parasitoids of Cimbicidae sawfly larvae, nice find!

I think it might be an Adeliinae, Adelius sp, but best to take it through the Braconidae key, www.royensoc.co.uk/wp-content/u...

The symbiont is known to attract Rhyssa ichneumonids. I have seen this often in a species of Rhyssa (Rhyssinae) (so probably the same for your orange Meagarhyssa (Rhyssinae)) when host infested wood is sawn it exposes the fungus (and frass) to the air, easily attracting the Rhyssinae ichneumonid (2)

This looks like a species of Odontocolon (Xoridinae) The hosts are immature beetles and in some cases probably sawflies too, the frass of which probably attracts some ichneumonids in search of hosts. Its known that woodwasp hosts can also introduce a fungal symbiont into the wood on oviposition (1)

Private woodland, msg u

Its Ophion sp, an Ophioninae, which includes Enicospilus–but they have quite distinctive wing structures and differ from Ophion in other ways. Also purgatus is a North American species, that has not been found in the U.K.

This is Pimpla rufipes

Yes a male of panzeri, the colour of the males can be quite variable

definitely Enicospilus, but i'd need to see a few more details to determine the species

Most, I would think, will know, they are very probably specimens taken from different locations, over many decades. The data that is attached to them, useful for understanding patterns in species distribution, environmental change etc

Lissonota sp (Banchinae)

This is Enicospilus repentinus. Enicospilus are nocturnal. However, males of some species are regularly found during the day and its thought they maybe rather less strictly nocturnal than females

Definitely not Pimpla, I'm pretty sure it's a Diplazontinae, genus is going to be difficult to say from what can be seen, could be male or female
