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 oreat 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.

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.

Roberflies (Asilidae). Robberflies(Asilidae)
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.

This is most common species.
It often occurs in the neighbourhood of oaks. It is already bee found

Anthrax anthrax. Genus Anthrax. Familiy Bee flies (Bombyliidae).
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.

two species similar to the Villa modesta. Namely Villa hottentotta and Villa
longicornis. On the abdomen of the female are white bands and at the end
at both sides yellowish-white hair tufts. The males don't have the white bands and
the hair tufts are very white. The wings are clear. Only the front is brownish.
In the Netherlands you can find them all along the coast.
The female lays her eggs in a hole in the sand, which is filled with sand, dust

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.

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.

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.
