Family Blowflies (Calliphoridae)
Blow-fly. In older English means blow meat. The blow-flies lay their eggs on
it. Blowflies feed on nectar and other sweet liquids. Here you can find
more information: http://en.wikipedia.org/wiki/Blow-fly
Most Blowfly larvae usually live in carrion or other decaying organic
matter.
Greenbottle
Family Blow-fly
(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".
Melinda spec.Family
Blow-fly
(Calliphoridae)
In the Netherlands there are two species Melinda gentilis and Melinda
viridicyanea.
A much smaller member of the family.
A much smaller relative. Here you see the fly
on a flower of a Lesser celandine. In early April there were many in the
garden.
It shines beautifully. Only when you enlarge the photo, you see the many
hairs.
Blue bottle fly (Calliphora vicina) Family Calliphoridae
Everyone knows the bluebottle. It's a beautiful fly
(I think) because of metallic blue-gray coloration. The Calliphora vicina
has bright orange cheeks. That's a different from the Calliphora
vomitoria.
This bottlefly lays its white eggs on a variety of bait.
Calliphora vicina are
found throughout Europe and the U.S.A.
Length 8-12 mm.
March - November.
Here it is blowing bubbles.
Blue bottle fly (Calliphora vomitoria)
Family Calliphoridae
The Calliphora vomitoria
hasn't the bright orange cheeks.
Under the head it has golden hears. Also behind the head, but that is
difficult to see on this photo.
This bottlefly lays its white eggs on a variety of bait.
Not as common as the Blue bottle fly (Calliphora
vicina)
Length 8-12 mm.
March-November.
On
this photo you can see the golden hears
Cluster
flies (Pollenia) Family Blow-fly (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)
Length about 7 mm.
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.
Melanomya nana
(Calliphora vomitoria) Familie
vleesvliegen (Calliphoridae)
Until recently, Melanomya was counted to the family Rhinophoridae. Stéphane thanks for

sitting on a Lady's mantle.
