Blue Fly - Protophormia terraenovae

Moved

Moved from Blow Flies. Identification confirmed by T. L. Whitworth:

"Yes, this is a female Protophormia terraenovae. It is a little nontypical in that it doesn't show the flattened mesothorax seen in many specimens."

splendid --thanks all!

And...

Thank you V. It's an interesting coincidence that the first P. terraenovae images on BugGuide come from Newfoundland, a.k.a. "Terra Nova".

thinking, Cynomya cadaverina

Moved from Flies.

Not Cynomya

Cynomya is lankier, does not have a strongly metallic thorax, and resembles a bluebottle. I'd say maybe Phormia regina or Protophormia sp. but I can't tell from these images. Any shots of the lateral thorax or closer crops of the dorsal thorax? Check out couplet (3) of Chrysomyinae key on Blow flies of eastern Canada (1).

yes, of course... my bad

hope Mardon adds some helpful pics from his archive

Thaks for all the help.

When I originally posted these photos, I didn't realize that the 560px limit was no longer in effect. I've just uploaded full-resolution images of all the photos that I have of this individual. The photo attached to this thread is not full size because I couldn't replace the photo without deleting the comments. Instead, I have added a second version of this same photo that is in full resolution. I did not get a lateral view. It flew away before I got that shot. :(

560px...

...has never been an imposed limit, just a guideline --apparently meant to alleviate server workload but in fact badly hurting chances of reliable identification on too many a case
(one restriction that is still in place is that to see someone else's pics full-size one has to have an 'editor' or 'expert' BG account)

Protophormia terraenovae?

From what I'm getting from the enlarged image (thanks!), I'm not seeing obvious presutural acrostichal bristles (Phormia regina has short ones present), and the dorsocentral bristles look to be very long (should be short on Phormia). I think these features should make this Protophormia terraenovae. Maybe wait and see what John Carr or Brad Barnd think, but I believe this is the first confirmed image of this species on BugGuide.

Edit?

You should be able to replace the photo by using edit and uploading the new image in place of the old one, and the comments should be preserved.

Thanks

Worked great. I wasn't that smart this morning. :(

Expert opinion?

Does T. L. Whitworth still identify flies for BugGuide on occasion? Protophormia would be a new genus for BugGuide.
