                                           Gnats (Nematocera)

Gnats look like slender flies. Although some species such as some crane flies can be mistaken for wasps and moth flies for small moths. A difference with flies are the antennae. The antennae of gnats have many segments. The antennae of flies have always three segments. 
All gnats have a snout. Most species don't bite (stabbing). The best known corrosive species belong to the family mosquitoes (Culicidae).

Crane flies (Tipulidae)      

Crane flies (tipilidae). They have  a long and thin body and very long, thin legs. The family Tipulidae includes three subfamilies: Tipulidae, Cylindrotominae and Limoniinae. They live in the same way.  The adult crane flies don’t eat or  eat only a little nectar. They live only to mate and live not long. 
The female has a pointed tip which she uses to push her eggs into the soil. The larvae feed on the roots of plants. They can bee a pest  because the damage to lawns.

Tipula helvola. Family Crane flies (Tipulidae). Male. 

Tipula helvola is a relatively small species (wing length 12-16 mm), which is rare in the Netherlands. The first antenna segments are brown. The other antenna segments are at the bottom dark. On the light brown or brownish gray thorax is in the middle a thin brown stripe. 
In and near deciduous forest.

Tipula lateralis. Family Crane flies (Tipulidae). Female.

Tipula lateralis is distinguished by the light stripe that runs down the middle of the abdomen. On the chest is a black line, that starts just behind the eyes. It also has strikingly patterned wings. It is very similar to the (in the Netherlands rare) Tipula couckei. The larvae feed on decaying plants on the bottom of the ponds or streams. The length is about 13 mm for males and 16 mm for females.
March - October.
Palaearctic.

Window Gnat  Sylvicola spec. Family Anisopodidae. 

Another long legged fly. It  is related to the family Chironomidae (Non-Biting Gnats or Midge Flies)
No fear, it is a non-biting gnat.
I don't know wich species. A common window gnat is Sylvicola fenestralis. In the Netherlands are six species.
They have 16 segments of the antenna.
They have got their name because they are attracted to light especially  illuminated windows.  
Their color also can be reddish.
This photo is from March 2009.

The larvae lives of vegetable waste.

German: Fenstermücken 

Bibionidae
St Mark's flies are no flies. They are gnats. You can see them in the early spring (often in groups). The males have larger bulbous eyes than the females.
The larvae feed on decaying organic matter and on the roots of grasses.

The larvae Bibionidae (Bibio or Dilophus: detail of anal opening is necessary to know the species.) 

The larvae resemble leatherjackets with a black head. These larvae I found in October 2008. Very late in the year for these species.
A difference with the leatherjackets are fleshy outgrowths of the skin and the entirely chitinised, external head.
They have no legs.

Gall midges, gall gnats (Cecidomyiidae, Cecidomyidae)
Small midge. Length 0.5 - 3mm. Sometimes larger. They have hairy wings with few veins. There are three subfamilies: Lestrmiinae, Porricondylinae and Cecidomiina. Some larvae of the subfamily Cecidomiina feed on plant tissue, causing gallnuts (like gall wasps). They can be harmful. Other larvae live in mushrooms, dead wood or are predators.

Biting midges (Ceratopogonidae).
In the United States and Canada: No-see-ums, midgies, punkies. Small biting midges from 1 to 4 mm.

Usually they are not to identify from photographs. The female midge can stabbing to suck blood. These are the midges of the genera Leptoconops, Culicoides, Forcipomyia. They often feed on nectar and honeydew.
In rest they have a bent posture as a Chironomid. However, they are broader. The antennae of the males are more or less hairy.
The larvae live in moist conditions, such as puddles, damp earth, rotting material, cow dung etc.

In the Netherlands there are the two species Sphaeromias fasciatus and Sphaeromias pictus. A third species Sphaeromias miricornis is also seen as a pale variety of Sphaeromias pictus. The differences are small (inter alia in the hairs on the scutellum). See this Polish information. Females feed on small insects. The males do not eat.
The larvae live in water.

A Chironomid don't sting. At rest the wings as they have a roof like folded.  They are difficult to identify. In the Netherlands there are more than 400 species. The length of the different species varies from 1 to 10 mm. 
The larva resembles a red worm and is eaten by fish. The larvae of most species live in the mud and water between underwater plants.
This Chironomid was about one cm. It's a female, for males have plumose antennae.

Culicidae
In this family females feed on mammals (humans, cattle) blood. They have slender legs and wings. The antenna has 15 segments. The antennae of males are long and hairy. The larvae are found in standing water. They feed on algae etc. Males typically feed on nectar and plant juices. The females suck blood. The proteins in the blood are used to develop the eggs.

Maybe: Banded mosquito, Culiseta annulata mosquito (Culiseta annulata, syn. Theobaldia annulata) Female.  Family Culicidae.

I have read, that Culiseta subochrea is very similar. And there are in the Netherlands more species. Namely: C. alaskaensis, C. fumipennis, C. morsitans, C. ochtroptera. A large mosquito with white rings on the legs. This mosquito can hibernate in buildings. Males can be recognized by the long hairy antennae. See the pictures.
The Asian tiger mosquito (Aedes albopictus) looks also like the Culiseta. This mosquito is native to Asia but has invaded southern European countries. Aedes albopictus is an important vector for the transmission of viral pathogens. Also with white rings but darker.
Culiseta annulata is less dangerous, but people are stabbing by this mosquito.

Fungus gnats (Mycetophilidae).
The family consists of many species, which are difficult to identify. A strongly humped thorax. Length of most types of 4 to 8 mm. But sometimes they are smaller or larger. Brown, yellow or black and not stabbing. The wings are often clear, but may also be tinted, and have a pattern. The larvae live in mushrooms, but also in mosses and in all kinds of moist materials.

Moth flies, drain flies (Psychodidae) 
Small 3 to 5 mm. They look like small moths. They have hairy wings. The antenna consists of 13 segments.
The eggs are laid in murky water or moist organic material. The larvae and adults feed on fungi, bacteria, decaying matter. The adult moth fly likes nectar too. By this way of life we find them often in wet areas like toilets. They are not harmful, but can be annoying.
They are all over the world.

March 2009.  
I have in the garden a trunk of a dead apple tree. There often are different species of flies on it.  Two little gnats (5 mm) were walking on this trunk. 
There are many little gnats, belonging to the family Sciaridae   Usually they are not  to determine from a photo. Length  1 mm to 7 mm. They are a non-biting gnats. Larvae often live in decaying organic material.
The same month I found a much smaller species. About 2 mm.

These tiny gnats flew and walked everywhere in our house. After some searching, I saw that they were mainly at two plants in the bathroom. A moist warm place. When I put the plant in fresh soil the Sciaridaes were gone. (You should not immediately put the plants back, because eggs can be laid again.) They were about 2 mm. The species was not to determine. Meanwhile I have a better camera than in 2009 when I photographed the gnats above.

Winter crane flies (Trichoceridae).
The family consists of two genera in Europe. Namely Dazosma (late summer - early autumn) and Trichocera (autumn - spring). Length 3 to 8 mm. Usually pale and not stabbing. The larvae live in moist soil, decaying material etc.

A charateristic of the family Trichoceridae is a short curved anal vein. The Diazosma has a slightly longer vein. But that is not visible in this picture. Given the time of year it's more likely that it is a Trichocera. They look like the Tipulidae, Tanyderidae, and Ptychopteridae, but unlike these families the family Trichoceridae has ocelli.
The length of this gnat is about 8 mm.
