This looks like a Blow Fly (Family Calliphoridae), very likely in Subfamily Ameniinae & Genus Amenia. Example of similar is Amelia chrysame.

Thanks Koprrine - I use the lucid carrion fly key - which is a bit difficult as it uses a lot of features you don't see in even a good photo

On iNat, Tony_d has commented that they think it's Chrysomya sp. (genus) based on:
My ID is based largely on chaetotaxy (major bristling) - this fly is definitely not Lucilia based on that - note how reduced the major bristles are in size and numbers on the scutum compared to the feature pics for Lucilia - a more specific character is this fly has only one pair of postsutural acrostichal bristle pairs (medial pair immediately in front of scutellum), whereas Lucilia has 2 to 3 pairs of postsutural acrostichal bristles (row between medial scutal cross-suture and scutellum).

Appears to lack flap like plates that you find on lower sides of scutellum - third segment of thorax (mid body)

There was a suggestion over on iNaturalist that this is Genus Chaetophthalmus.
Calliphora stygia
