This is the most interesting find! Certainly this is not a native species and it comes from Palaearctic region! It belongs to the Chrysis ignita species group, which consists of many very similar species. For simplicity (or ignorance) Palaearctic ones have often been lumped together under the name Chrysis ignita. Please keep the specimen since only with inspecting actual specimen it is possible to identify it to species with certainty. As far as I know none of these cuckoo wasps with red abdomen from this species group have been found from North America yet. Introduction of one or many species of this group to North America is very likely since they are common in Europe and they are often parasites of wood nesting potter-wasps. If you are willing to ship it to me (to Estonia) I can identify it for you.

 
Interesting...
Well that's good news for me if I'm the first person to have seen a Chrysis ignita type of Chrysid in North America... The funny thing is I've seen one about three years ago in the west end of town... foraging around some concrete hole filled wall where there were many Eumenine wasps.... It was in some alley at the back of a building... I tried to catch it but I unfortunately failed which left me very angry! haha so far I've only ever seen two... so I thought that they would be a somewhat regular occurrence in North America...

About sending it to you... im not sure... I don't feel comfortable sending a rare enough specimen to someone I don't know.... Where are you located?

 
Hi!
I am located in Estonia, which is a small country in northern Europe. I understand if you don't want to send the specimen that far away to someone you don't know. My concern is to get the specimen correctly identified instead of naming it just as Chrysis ignita. This can happen easely since there are no specialist of the Palaearctic species of this group in Canada nor US.

Thanks for additional photos but unfortunately these does not help much. I would need higher magnification and photos of the end of the metasoma, dorsal view of the metasoma, ventral view of the metasoma, dorsal view of the thorax and head, lateral view of the mandible etc. But even with these pictures it might not be possible to be confident with the identification.

Another option is that I could send you a set of European species and you'll try to identify your specimen by comparing yours with them. This might sound great but actually it is not as easy as it seems and you would need some experience to understand intraspecific variability of important features.

One more option is if you could send me a tissue sample of the specimen and I'll run a DNA analysis. For this you could send a leg but this means damaging the specimen. You can also try to get some muscle tissue from the thorax but this operation requires experience to pull it off without destroying the specimen.

 
Oh one more thing
I thought about it and I could send it to you, but would it be possible if you sent it back?

Thanks

 
Sure,
returning the specimen is not a problem. I am glad that you are willing to ship it to me for inspection since as I wrote: I could send you specimens for comparison but I still wouldn't be confident with the identification that you might make. However I can send you some European specimens when I return you the specimen anyway, just as a gift, you can keep them. Several species are common enough, so you can keep the specimens but if you want see a full set of species then I need you to return some of the most rare ones.

Please write the reply to my private e-mail address vilts[ät]ut.ee (replace the [ät] with @).

Thanks,

 
Ok
Hi Villu....

I'd appreciate if you could send me some Palaearctic specimens so I could compare them to mine...

However are you giving them to me or do I need to send them back to you?
The terga of my Chrysid are all red but the sterna (the cavity where it allows the wasp to curl up to get into defence mode) are actually a blue-ish green-ish colour... I don't know if all the Chrysis ignita species have this feature..?

I would be pleased to take different angle shots of the wasp to be able to simplify the identification of the Chrysid... but I would rather not pull any appendages off since this is my only specimen and I don't wish to damage it.

If this isn't too much to ask would it be possible if you could send me a few micropins and a small plastazote platform so I will be able to double mount my specimen? Do you recommend side pinning or direct pinning?

I appreciate all of your offers!

Thank you

Devon
