Shiny metallic species, blue, green, black, occur in several families and a thread on this topic referring to these species may be useful for initial identification. Here is #1:
Initially I thought this fly was a Lonchaeid because of its similarity to:
See: HERE. But it has too many dorsocentral setae.
It is a blueish-black metallic fly, length 7.5 mm (28 September, NB, Canada).

EDIT: Thanks Nikita and Kahis
#1 Muscidae: Hydrotaea sp., female

It is female of Hydrotaea, Muscidae. Can't say more about Nearctic species...

It looks like the widespread to the holarctic species Hydrotaea ignava, but you may have other, similar species in NA.

Families that have more or less metallic looking species ...
Muscidae (as mentioned)

... and probably more

Acroceridae --> Lasia spp. ; Eulonchus spp. but I'm not sure if it these are Palearctic. At least, I know they are Holarctic.
Milichiidae ---> Madiza (glabra); etc
Sepsidae. Smile

Indeed, there are lots of families with metallic flies. Smile

Muscidae > Neomyia viridescens (female)

Stephane Lebrun wrote:
Neomyia are very similar to Lucilia in appearance because of the angular bent on vein M, but Neomyia have got shiny metallic green frons, occiput and genae (....). In female, the frons is very wide, with broad orbitale plates.

How to ID the very common Lucilia sericata http://www.dipter...ad_id=8290
Further info on how to separate from L cuprina http://www.dipter...d_id=12031 (unlikely for northern Europe and if no sheep anywhere near.)
