flies (Muscidae) Soldierflies
|Diptera - two-winged. In this order belong all flies (Brachycera) and
gnats mosquitoes, crane flies, black flies, midges, long-horned flies (Nematocera).
In Dutch only two names Brachycera = vlieg and Nematocera =
mug. Much easier :-)
The second pair of wings has been changed into halteres at the Diptera (Club
shaped organs behind the wings).
Like all insects, the diptera have three pairs of legs. Fly larvae and gnats larvae have a complete
metamorphosis (egg - larva - pupa - adult).
Difference between fly (Brachycera) and gnat,... (Nematocera): Antenna of a fly consists of three segments. The antenna of a
gnat consists just like for example the antenna of a wasp of many segments. Sometimes they look like wasps, but they have four wings just like the other insects.

Ctenophora pectinicornis and Nephrotoma

More information about gnats (Nematocera) you can find on Subpage
Of some families I have many species. Those families, I've put on a subpage. Of each family is an example on this page. Below is a link to the subpage.
I also created a subpage with families, which consist mainly of small flies. Hover flies are on two separate pages.

|Other families of flies. They are arranged alphabetically.
I have used the scientific (Latin) name.
flies, which catch other flies in the same way as dragonflies with
their forelegs. The
short, strong proboscis is used to stab and inject victims with saliva
containing neurotoxic and proteolytic enzymes. The fly then sucks the
liquefied meal through the proboscis.
robber flies have stout, spiny legs.
They aid in pray capture.
Larvae live in the soil and decaying wood. They also feed on other insects.

Bee flies (Bombyliidae)
Bee Flies have pubescent (hairy) bodies like bumble bees.
Anthrax anthrax. Genus Anthrax. Familiy Bee flies
It's a black fly. The wings are black. Only the edges of the wings are partially transparent. On the black abdomen are white hairs.
The larvae live in nests of mason bees. At the entrance of the nest the female lays the eggs. The larvae eat the pollen and nectar supply. The eggs and larvae of the bees are
also eaten by the larvae of the Anthrax anthrax.
Length: 7 - 13 mm.

It has striking dark brown wings with clear spots. The body is gray-brown, and behind the head is a collar of red hairs. On the abdomen are white spots.
The larva seems a parasite of the larvae of digger wasps on caterpillars.
In the Netherlands they occur in the sandy heathland and the dunes .
Length: 9-14 mm. Europe, Near East.
Thick-headed flies, Conopid flies (Conopidae)
Thick-headed flies have long antennae, a long snout and a curved body.
Thick-headed flies because of the thick (inflated) head
Conopid flies deposit eggs on the abdomen especially of wasps, bees and bumblebees. This happens in flight. The larvae are
internal parasites or endoparasites. The larvae develops inside the abdomen.
The development is completed within 10 - 12 days, when the host is killed.
To determine the
Conopid flies you can use "de veldtabel van John Smit" blaaskopvliegen van Nederland en België.

Horse-flies, gadflies ( Tabanidae).
In our garden we almost never see a gadfly. The fly feeds on nectar and pollen. The female sticks and then sucks blood from humans and animals. It needs
blood for the eggs to develop. The larvae are aquatic, semi-aquatic or terrestrial and
feed on other invertebrates such as worms, snails and other Diptera larvae, including their own species.
(translated text Pjotr Oosterbroek) There are about 38 species in the Netherlands. A horse-fly has no arista on the antenna.

muscae. cf: very probably but there are more species of Entomophthora. Familie Entomophthoraceae.
With countless enemies flies don't have an easy life. This fungus is also deadly. I placed it on the fly page, because many people think that it is a special kind of fly with these white bands.
All kinds of flies can suffer from it. This is a Phaonia family house flies (Muscidae). The Dungfly (Scathophaga) you also frequently see with this fungus.
The fungus grows also inside the fly. If it reaches the brains, it affects the behavior of the fly. Shortly before its death the fly crawls to a high point. As a result, the spores can be better spread. The belly (abdomen) swells, the legs and wings are spread. Around the abdomen, you see the white bands.
I want to thank everyone, who has helped me (waarneming.nl)
to identify. In particular, Joke van Erkelens, Robert Heemskerk, Mark van Veen,
Gerard Pennards, Niels-Jan Dek and Han Endt. With the determination of Tachinidae I have had
much help from Theo Zeegers and Chris Raper.
