Greenbottle
Family
Blow-flies (Calliphoridae)
The
name blow-fly comes from an older English term for meat that had eggs laid
on it. Flies in this family are often metallic in appearance.
Maybe Greenbottle(Lucilia
caesar) Greenbottles are found everywhere. On carrion, dung, but also on
flowers. The
larvae feed on carrion and adults visit flowers for nectar. It
has a beautiful metallic bluish green colour.This
is the most widespread and common species. As always there are similar
species.
Heer is a blowfly in the
sun. That white face most likely is, because the fly is just "born".

found throughout Europe and the U.S.A.

Cluster
flies (Pollenia) Family Blow-flies (Calliphoridae)
When the spring flowers appear (Crocus, White
Squill) you will see this fly.
They belong to the genus Pollenia. Identification of Pollenia species is
mostly only possible under the microscope
They have short golden hairs on their body. (not always visible)

The eggs are deposited on the soil near earthworms on which the larvae
parasitize. I do not know that applies to all species.
Here the flies are covered with pollen. The lower flies are also Pollenia
sec.
