Hoverflies, Syrphidae     

Hoverflies, Flower Flies (Syrphidae) One of their characteristics is their bee, wasp or bumblebee mimicry, whereas they are completely defenceless. Flower flies cannot sting. They have same the bright colours, and sometimes the dense hair covering of bumblebees. 
Hovering is a speciality, but they are also fast and very manoeuvrable.
The difference with other flies is the spurious vein. This vein neither ends nor connects with other wing veins. The spurious vein just ends for the edge of the wings.  
Cell 2 is closed. The closed cell 4 is longer or as long as one third of the length of the wing.

The arista is on the side of the third antennal segment. Not on the top.
On the thorax are no stiff hairs like other flies.

 Wing:
   1, 2, 3, 4: closed cell
   a: vena spuria or a false vein
   b: stigma 
   c: cross vein
   d: outer cross vein
Antenna:  
   1: third antennal segment (you can't see the other two on this photo)
   2: arista


Females have smaller eyes which are placed farther apart. The eyes of the male meet at the top of the head. Of course there are exceptions. Than you have to look at the underside of the abdomen, males have curbed asymetricla genitalia. The abdomen of the female is more pointed with inconspicuous genitalia.
Many species feed mainly on nectar and pollen. The larvae (maggots) eat a wide range of foods.


Exceptions 
No vena spuria: Eristalinus sepulchralis and Psilota anthracina.
Arista op the top: Callicera and Ceriana
Stiff hairs: Ferdinandea. Less: Volucella, Cheilosia, Brachyopa and Chamaesyrphus.

Eristalis  

These hoverflies are Honeybee mimics or (Eristalis intricaria) sometimes bumblebee mimics. The larvae are rat-tailed maggots.

The larvae of Erisalis and Myathropa are rat-tailed maggots . The larvae of Erisalis and Myathropa are rat-tailed maggots    The larvae of Erisalis are rat-tailed maggots and feed on rotting organic material in stagnant water. The tail is a breathing tube.
When fully grown, the larva creeps out to pupate.

Family hoverflies (Syrphidae).
A small, stocky cheilosia. The eyes are hairy, the face is hairless. Brushes on the edge of the shield. It is variable in terms of colour of hairs, legs and antennae.
It is found in many different habitats.
The larvae mine in stems of different plants of the family Asteraceae or Compositae. For example, in Yarrow.
Length: 5 - 7 mm. April - September. Two generations.
Palearctic. Photos 10-04-2012, 18-9-2012.

Female. Genus: Gitjes (Cheilosia).   Cheilosia albitarsis. Genus: Gitjes (Cheilosia). Family hoverflies (Syrphidae). Not in the garden but in the dunes about 4 km from my house.
Black, hairy eyes (not easy to see), face without hairs. Black legs, but the middle segments of the tarsus of the front leg are light. Female with yellow-brown wing roots. It looks like the in the Netherlands rare Cheilosia ranunculi. 
Differences according to Menno Reemer (translated): In C. ranunculi the last tarslid of the foreleg is widened. And males C. ranunculi additionally have slightly yellowish wing roots, as females C. albitarsis have this too.  A useful field characteristic to recognize the C. ranunculi males between the C. albitarsis. For final determination you will always have to look at the tarsi.
Often found near buttercups. The larvae live in the roots of the sharp buttercup and creeping buttercup. (perhaps in other species buttercup)
Length: 7 - 9 mm. April - July. One generation.
  Holarctic. Photos 6-05-2014.    

Pipiza

Not quite sure. It is very similar to Pipiza bimaculata. A difference is that the last two segments of the tarsus of the front legs of  P. noctiluca are usually yellow. The other segments are black. All segments of the tarsus of the front legs of  P. Bimaculata are black.
A black abdomen with two yellow spots. Bright wings with a vague spot. Pipiza hoverflies have a flat face.
As you can see from the photos, there are two spots on the abdomen. Sometimes they miss those spots. (Often in males). As the photo below left.
I often see them on leaves. But they also visit flowers. The larvae  feed on aphids.
Length: 6 - 10 mm. April - September.  Photos 28-9-2008, 29-4-2009, 1-5-2009, 14-5-2010.

This would be a Pipiza bimaculata, but it is not certain. This would be a Pipiza bimaculata, but it is not certain. Photo 14-5-2010.

Slanke platbek (Pipiza luteitarsis) Genus: platbekjes (Pipiza).  Pipiza luteitarsis. Genus: Pipiza. Family hoverflies (Syrphidae).
The whole tarsus of  front legs is yellow. Of the other legs are the last segments of the tarsus yellow. The abdomen is golden yellow hairy.
Han, Gerard, Menno, Jaap thanks for the help with the identification of this fly. This male is not black and therefore difficult to identify. In the Netherlands it is a rare species!
Length 7-9 mm. April - May. Europe.

Heringia is a family, consisting of small black hoverflies. Females of this family are hard to identify. But the males are also not easy to identify from a photo. In the Netherlands there are seven species.
Like Pipzella it has a flat face. The third antennal segment is less long.
You see the most species oft on the leaves. Length: 5 - 8 mm.
The larvae  feed on aphids. Photos females 3-7-2011.  Photo male 29-7-2009.  
  


Pipizella

Usually it is not possible to indentify pipizella species from a photo.
Probably Pipizella viduata. That is the most common of the six species in the Netherlands.
They are small black hoverflies with a flat face. The third antennal segment is quite long. The legs are black with yellow.
It is found on umbelliferous. Here on celery.
Larvae are found near root lice include on fireweed.
Length 5 - 7 mm. The Palearctic. Photo 11-7-2010, 14-5-2013.

As you see a very small black hoverfly.
On this photo on the flower of a Welsh poppy (Meconopsis cambrica)
The Melanogaster hirtella is (just like the Cheilosia albitarsis) a real buttercup species. The Melanogaster at the other photos is sitting on a marsh marigold.
Often in meadows near water. The eggs are attached under leaves of plants near the water. The larvae live along the waterfront. They overwinter as larvae.
Length: 6 - 8 mm. April - July. Photos 14-5-2008, 24-5-2011, 14-5-2013.   
Chrysogaster solstitialis. Genus: Chrysogaster... Chrysogaster solstitialis. Genus: Chrysogaster.. Chrysogaster solstitialis. Genus: Chrysogaster.  Chrysogaster solstitialis. Genus: Chrysogaster. Family hoverflies (Syrphidae).
A dark hoverfly. The body is black and the wings are completely darkened. Thorax male is dull black, the thorax of the female has a purple sheen. Strikingly large red eyes.
Chrysogaster solstitialis you often find on umbelliferous. The fly on the picture I found in the scullery. The first time that I saw this species in our garden. Since 1990 it has expanded to the west and north of the Netherlands, where we live.
The larvae live in water with rotting wood.
Length 6 - 8 mm. April - September. Two generations.

Not quite sure, because it is similar to the (in the Netherlands) very rare Paragus tibialis.
A completely black paragus with occasionally some red on the middle part of the abdomen. The face is yellow with a black center stripe. The legs are yellow. The eyes are slightly hairy.
The paragus you often see in the sun between low vegetation near bramble thickets.

The larvae  feed on aphids.
Length 4 - 6 mm. April - October. Holarctic and afrotropic. (not in Northern Scandinavia.) Photos 11-9-2012.
