Why not vertebrata?

Seems to have dark apex to hind femur

Not sure

I'll double check with Don.

Rhagio tringarius

Don Webb curated our collection back in the 90's, and we didn't have a single tringarius. Tom gave me the specimen in question above, and with the comments of "Christmas" below, spurred me to use Chilcott's key. It trots right out at tringarius. At that time it was known only from one spot in Nova Scotia, but checking through our accumulated unidentified material it seems to have appeared in the mid-90's here. If I have identified them correctly, they seem to be a bit bigger than vertebrata.

R. tringarius

Ya, it seems they were only known from a single spot in 1958 Nova Scotia but now they appeared to have spread to become one of the most common Rhagio around.

As of today I have in my possession a number of specimens for each sp. mentioned in Chillcott's key from the CNC on loan and am on my way to the Guelph collection tomorrow to make use of their micoptics for better photos and to find more characters.

So hopefully I'll be able to add some shots of R. tringarius and other sp. of Rhagio in the near future.

Rhagio tringarius

it keys out to Rhagio tringarius
vertebratus has dark bands/rings rather than spots on the tergite.

Size?

This one was a monster compared to the 9mm of the others identified as Rhagio tringarius.
Could you please fill in your bio, since the handle "Christmas" doesn't tell me anything about your qualifications?

Apologies for the late reply

Hey sorry for such a delayed reply I was swamped with work in Guelph which didn't have a properly identified specimen of vertebratus for reference, and wasn't able to get to Ottawa's Canadian National Collection (CNC) till recently.

I currently working at the CNC but not at the Diptera department at the moment so I've only been able to take some quick poor quality shots for reference identified by D.W. Webb.

I'm catching these commonly at the moment (20 July) in a Malaise trap in my garden in Nova Scotia and would also like to know the ID. Mine are spotted like Tom Murray's photos, not banded, and around 12 mm long. This 'Apologies...late reply' is unhelpfully ambiguous as to the ID: is 'Christmas' retracting the R. tringarius ID and defaulting back to TM's R. vertebrata ID, or what? Can we at least get a clear statement on this?

… Steve Shaw, 20 July, 2010 - 5:47pm

Sorry for the ambiguous reply

I meant to say its still R. tringarius and was posting a link to what R. vertebratus ID by D.W. Webb in the CNC actually looks like as a comparison.
