Photo from Jerusalem, 30 Oct 2018.
Maybe Chrisomya albiceps, or perhaps Lucilia sericata? Both are known here; what are the identifying features?
Sorry for the low quality.

Clearly a Chrysomyia. Looks like Ch. albiceps, as far as I can tell.

Most Chrysomyinae have weak hairs instead of distinct bristles on top of the thorax. Calliphorinae and Lucilia have typical muscoid bristles in clear rows much stronger than background hairs.

And in western Palaearctic: black hind margins on tergites indicate Chrysomyia (not true elsewhere !)
