The family flies, which for the most part consist of very small flies, I have put on a separate page. It's an alfabetical sequence. I have used the scientific (Latin) name of the families.

Miner flies (Agromyzidae)
Miner flies. The larvae mainly mine leaves and stems of herbaceous plants. But they can also occur in roots and seeds.

Agromyza ferruginosa. Family Agromyzidae.
Agromyza ferruginosa. Family miner flies (Agromyzidae).

The larva of Agromyza ferruginosa mines on plantsof the borage family (Boraginaceae) like Anchusa, lungworts and comfrey. A number of eggs are deposited at the underside of the leaf. First the larvae eat a communual corridor. Than they make a large brown blotch.
Here information..
Determined by Milos Cerny from Czech Republic. Thanks Milos.
I haven't measured the fly. I think about five mm. It is striking orange.    Europe.

Napomyza sp. Family miner flies (Agromyzidae).
Very small miner flies. About 2 - 3 mm. I had asked about these flies on Diptera and received answer from Miloš from the Czech Republic:
I think the same as the fly on the site
http://aramel.fre...15-7.shtml Phytobia lateralis. But I couldn't find information about this species.  
Answer: The fly on the site and this specimen isn't Cerodontha (Poemyza) lateralis, rather is it Napomyza sp.
Miloš  
Maybe Napomyza gymnostoma from Central Europe. This fly can be harmful.

Holly leaf miner. (Phytomyza ilicis). Family miner flies (Agromyzidae).
No picture of the 4 mm large dark holly leaf miner. In May, June the fly lays its eggs with an ovipositor in the underside of the petiole or midrib of the young, yet soft leaf of the holly (Ilex aquifolium). The young larvae tunnels within the midrib to the leaf tip. In a leaf are one to a maximum of three mines. In December, January, you can find the yellow sometimes purplish, irregular blotch on the holly leaf like in the picture. Pupation is in the leaf.
Chickadees pick many larvae from the holly leaf.

Grassflies (Chloropidae) 
Although there are larger flies, most are very small. 1 to 4 mm. Often yellowish, greenish. The larvae often feed on living or dead organic matter. Some live on flowers and stems of grasses and they can be harmful.

Grassfly spec. Thaumatomyia spec. Family Grassflies (Chloropidae).
Grassfly spec. Thaumatomyia spec. Family Grassflies (Chloropidae).
 
The small flies in this family are very similar. (Therefore spec.) These flies are yellow with black stripes, but there are also flies with other colours. According to Jan Willem van Zuylen (translated): Thaumatomyia and Chlorops can be quite similar. One of the features to distinguish the two genera is the scutellum (less or more spherical), which often don't show up well on the photographs.
These photos were taken in March. 
The larvae of the grass fly live in grass stems. Length: 2, 3 mm. March - November.

Oscinella. Family Grassflies (Chloropidae).     

Frit Fly - Oscinella frit is possible. But it is very similar to Oscinella pulsilla Meigen and O. grossa  Mesnil. This species is black and shiny.
About 3 mm. The larvae feed on various plants of the grass family.

Clusiidae.
In the Netherlands in the family Clusiidae there are 6 species. Usually small flies (1.5 - 8mm). As far as known the larvae live in decaying wood of deciduous trees.

Drosophilidae 
Very small flies, but there are also some larger species. Length 1.5 to 7 mm. The larvae of most species live in decaying organic material. Such as fruit, mushrooms. However, there are mineerders and predators.

Shore flies, brine flies  (Ephydridae)
The flies of the family Ephydridae are often found near seashores and inland waters. They feed on algae, bacteria. They are tiny flies. However there are also lager members of the family.

At this moment only Ochthera mantis is mentioned in the Dutch species. But there are similar species and they maybe could occur in the Netherlands. (O. manicata, pale O. arctica, O. schembrii) 

A copper colored shiny fly. The thighs of the legs are swollen with thorns on the underside, so it can hold its prey. It has the attitude of a praying mantis. Unfortunately you can't see this on these pictures. They are are predaceous and feed on midges. 
The larvae of Ochthera feed on larvae. About 4-5 mm.

Hybotidae
Family members 1 mm to about 6 mm. There are three subfamilies. Namely Hybotinae, Ocydromiinae and Tachydromiinae. The arista is long. Slender legs. They often run back and forth. So they are difficult to photograph. They are predators of small insects.

Lauxaniidae 
The flies can be 2 to 7 mm. In the family are many different species. Matt, but also glossy. Black, but also colored. Larvae of this family live in different places. In fungi, decaying plants, in bird nests, sometimes they are leafminers.

Trembling-wing flies, Pallopteridae
A characteristic of many flies in this family is gray silvery white spot on the head. Many species have spotted wings. They often live in shady places. Size of the different species: 2.5 mm - 7 mm.We know little about the larvae. The larvae live under the bark of trees as predators of larvae of bark beetles and longhorn beetles. But there also seem to be species on flower heads or in stems of Umbelliferae which feed on plant juices.

This fly was also in our scullery. It often has its wings spread like the peacock flies, but it can fold the wings on its body like the Palloptera umbellatarum. The wing pattern is distinctive. The clear middle area of the wings is surrounded by light and dark brown markings.

The pattern of spots on the wings is similar to the Palloptera umbellatarum, but the wing edge is without shades. The same darkened transverse veins, but they are narrower darkened. In the middle of the wing edge, and nearly at the end of the wings is a dark spot. Thorax is grey, light brown abdomen, legs yellowish bruin. Until 2003 this species was unknown in the Netherlands. They are found from October to May. There are mainly found females. Length 5,5- 6 mm.
Larvae have been found in the stems of rushes, grasses and umbellifers.

Phorid flies (Phoridae)
Flies from 0.5 mm to 6 mm. Striking are the circular antennas with a long arista and the veins of the wings with the thick upper veins. The larvae live under different circumstances. (water, organic matter, parasitic ...)

Signal flies (Platystomatidae). 
Small to large dark flies (3-11 mm). They are dark and often with strikingly patterned wings. In Europe there are two genera. Platistoma (in the Netherlands only Platistoma seminationis) and Rivellia (in the Netherlands only Rivellia syngenesiae).

There are not many observations. Probably, this is the most northerly sighting of this species (2011).
It is spread throughout the Mediterranean area. In 2000 was the first sighting in the Netherlands.

The larvae feed on cat's ear (Hypochaeris) and sometimes with other species of the subfamily Cichorioideae. 
June - August. Length 3.5 - 4.5 mm.

Opomyzidae
Slender flies. 2 to 5 mm. Colours are different. The larvae live in the stem of grass. Sometimes they are harmful.

Opomyza germinationis. Family Opomyzidae. Opomyza germinationis. Family Opomyzidae.

Opomyza germinationis looks a lot like Opomyza petrei. To see the difference, the abdomen must be clearly visible. The abdomen of the Opomyza germinationis is for a large part dark. Only the last part is light brown. The abdomen of the Opomyza petrei is light brown with dark longitudinal stripe on the side. The wings are mottled. Approximately 3 mm. 
The larvae live in grass stems.

Geomyza tripunctata Family Opomyzidae Geomyza tripunctata Family Opomyzidae

I saw this fly walking on an euphorbia in the garden. There are three spots on the wings. Hence the name "tripunctata". The thorax of the Geomyza tripunctata is sometimes orange red. Then it is also possible, it is the in the Geomyza nartshukae.
Eggs are laid at the base of grasses. The grass shoots and young leaves are eaten by maggots. They pupate after about 30 days.
Length up to 4 mm. May to November.

Small dung flies, lesser dung flies or lesser corpse flies (Sphaeroceridae)
There are very small flies in this family. From 0.7 to 5.5 mm. Robust black flies. The first segment of the tarsus of the hind leg is swollen. The larvae live in decaying organic matter in dung and droppings. They don't fly very well..

A shiny dark fly with red eyes of about 3 mm, which can be found on our compost heap.
According to Paul Beech: Copromyzinae. Perhaps Lotophila atra, but if you can get a specimen for me I can tell you more / for certain.
I did not sent fly. It's therefore uncertain. Thanks Paul!

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, Niels-Jan Dek, Jan Willem van Zuijlen and Han Endt. With the determination of Tachinidae I have had much help from Theo Zeegers and Chris Raper. (On diptera)
