There are many species in our garden.
Characteristic: Small slender flies. Different colours. From yellow to
black.
Usually they are difficult to determine from a photo. Length from 4 up to 12 mm.
The wing vein M1 is straight and the anal vein long.
They feed on nectar and pollen but there are also predaceous species on
small flies.
When you want to see more species, you can look here.
The larvae are feeding on plants or decaying organic
matter. Sometimes they are miners.
German: Blumenfliegen
Anthomyia
procellaris
Family Root-Maggot Flies (Anthomyiidae).
The differences however are very small with the Anthomyia pluvialis / Anthomyia
parva Kabos
A. pluvialis has two names. The first name is the oldest.
Pluvialis means in
Latin rain: It seems to dance
before it is raining. Eggs on rotting
vegetation.
The Limnophora tigrina Family Muscidae is
a little bit similar
Photos 28-5-2010, 19-5-2010, 4-4-2011 Joke van Erkelens: A. pluvialis has a
black spot just above the top of the wing is separated from the larger
spot above. The two spots of the A. procllaris look like one spot. On the
hindtibia of A. procellaris about 5 to 9 dorsal hairs.
But the differences are small. It remains uncertain.
Calythea nigricans
Family Root-Maggot Flies (Anthomyiidae)
A small fly, which nevertheless strikes by the comparatively large eyes and the gray spots on the back and abdomen.
It is not often photographed in the Netherlands. I did not find much information.

Cabbage fly, cabbage root fly, root
fly or turnip fly (Delia cf. radicum) Family Root-Maggot Flies (Anthomyiidae)
The eggs are deposited at the base of plants including cabbage.
They are not fooled by fake
plants though. The larvae
are a pest of crops.
2 - 3 generations a year. 4 -7 mm.
Egle ciliata / Egle brevicornis
Family Root-Maggot Flies (Anthomyiidae)
Het eerste vliegje, dat na deze lange, strenge winter in maart zag. Het is
een voorjaarsvliegje.
Hoogstwaarschijnlijk Egle ciliata.

Emmesomyia socia
Family Root-Maggot Flies (Anthomyiidae)
It can also be Emmesomyia grisea.
The difference with the females are the hairs on the posterior rear thigh (E. grisea
has these hairs. E. socia has not) Thanks to Joke and Niels-Jan.
When it saw me, it hide itself on the underside of a leaf. I still succeeded to
take a few pictures.
The shins are light brown. The wings have a light brown tint.

Hydrophoria linogrisea Family Root-Maggot Flies
(Anthomyiidae)
I haven't found much information.
Hydrophoria lancifer
Family Root-Maggot Flies (Anthomyiidae)
Features: The beginning of the wings is yellow. The
prealar is long and the femurs are are dark (tibia yellowish) The wings of the fly on
these photos look darker than on most images.
Hylemya nigrimana /
Hylemya vagans Family Root-Maggot Flies (Anthomyiidae)
The photos are not so clear. ThereforeI'm not
entirely sure
Hylemya nigrimana and Hylemya vagans are very
similar.

Lasiomma seminitidum
Lasiomma seminitidum en Lasiomma
anthomyinum are very similar.
But from these flies I know it is a Lasiomma seminitidum. (Thanks Joke) Left
the male (photo 19-3-2011) and under the female. (photo 3-7-2011)
Here is more information: Lasiomma.
This fly is new in the Netherlands. Probably, it is often confused with
its well known relative.
Leucophora spec. Family Root-Maggot Flies
(Anthomyiidae)
This flies can be recognized by the shape of the head. Further determine from a picture is difficult.
Like par example Nomada (cuckoo bees), they lay their eggs in nests of bees.
Leucophora obtusa.
Family Root-Maggot Flies
(Anthomyiidae)
Determine from a photo is difficult. But Leucophora obtusa can now be determined.
Joke van Erkelens (translated) : Here we see quite clearly a ventral seta on the mid thigh.
Scutellum with rows of hairs on the sides and all over very hairy ....

Pegomya spec. Family Root-Maggot Flies
(Anthomyiidae)
The larvae seem to cause "foam cups" on Common Ragwort
Pegomya spec.
Root-Maggot Flies (Anthomyiidae)
A small fly. The buds of ivy are 4 mm wide. It was a little hazy. Therefore, the photos are not
very sharp.
In 20011, I have taken more photos.
Possible Pegomya bicolor or Pegomya solennis. To see this, you need a good view of the length of the prealar and the
colour of the palps. These species are common in the Netherlands and are leafminers. But there are more
similar species. Those species are miners on mushrooms. With thanks to Joke van Erkelens.
I want to thank everyone, who has helped me (waarneming.nl)
to identify. In particular, Joke van Erkelens, Robert Heemskerk, Mark van Veen,
Gerard Pennard and Han Endt. With the determination of Tachinidae I have had
much help from Theo Zeegers and Chris Raper. (On diptera)
