3.5mm wasp found inside twig - Oethecoctonus oecanthi - female

3.5mm wasp found inside twig - Oethecoctonus oecanthi - Female
Pleasant Prairie, Kenosha County, Wisconsin, USA
Size: 2.5mm
This tiny wasp was found inside a stem of Russian Sage -- inside a 'channel' where a Forbes' tree cricket egg would have been. I had found a similar looking wasp inside a prickly ash twig in the past. Since these current photos are clearer, I am hoping to get a confirmation on the species. It's good information to know for my study of Oecanthines. Thanks.

Date?
Do you have the collection date for this specimen? Lack of that data prevents these images from showing in the Advanced Search.
Also, it is an adult female, so I added that to the data field.

 
Not sure what date to put
The stem was opened in July - but I assume this dead individual failed to emerge the previous year after the eggs were laid (probably in August or September 2009).

 
I see
I have had the same situation a few times. In such cases I mention the date in the text and explain why I don't include it in the data field.
Such interesting find! I will start splitting twigs open :-)

 
Yes, I highly recommend opening twigs
...particularly those that have oviposit markings. I have also found 4 different types of mites.

Oethecoctonus oecanthi, female -- det. O.A. Popovici
his note: "Because of the distinctly excavate occiput I think that this wonderful scelionid is a female of Oethecoctonus oecanthi."

awesome addition!

Moved from parasitic Apocrita.

 
Thank you so much for the ID!
...thanks, v. Could you please pass along a note of thanks to O.A. Popovici? This is great information that I will pass along to my Oecanthinae circle of friends. The name 'oecanthi' is obviously intriguing -- I'll have to do some research on that etymology.

 
etymology is obvious: a genitive from Oecanthus
literally, "Oecanthus's"

 
I'm having trouble finding Oethecoctonus
...is it a different spelling of oothec? -- indicating 'egg' related?

 
finding it where?

 
Sorry, should have typed....
I'm having trouble finding the meaning of the WORD Oethecoctonus.

 
i think your guess is correct:
something like ootheca-piercer/borer -- along these lines

 
ktonos = slayer

 
Perhaps misspelled
The "Oetheco-" part may have been accidentally misspelled, or maybe intentionally, to play on the Oecanthus connection. Taxonomists sometimes take great liberties with the coining of names, causing much cringeing on my part.
