Ochlerotatus sticticus

Ochlerotatus sticticus ( Syn: Aedes stictitus ) is a Fly in the genus Ochlerotatus in the family of mosquitoes ( Culicidae ). The species was described in 1838 by Johann Wilhelm Meigen first time under the name Culex sticticus.

Dissemination

The species is widespread in Europe from northern Europe to the Mediterranean region and to Siberia and is also found in North America. In floodplains and wetlands it is in mid-summer in many regions of Europe next Aedimorphus vexans the dominant of mosquito.

Way of life

The females are active bloodsucking and especially during twilight hours or in shaded areas. Eggs are laid in the water. They are oblong, formed from 0.51 to 0.61 mm long and asymmetric. While they are on one side almost straight, they are very convex on the other below the center. Their surface is black. The larvae develop mainly during the summer floods in flooded wetlands and temporary water bodies. There they feed on the aquatic protozoa, bacteria and algae. Your development time will be shorter when the waters dry up quickly. The size of adult mosquitoes does not change significantly because of the shorter development Ochlerotatus sticticus. In Aedimorphus vexans, an also widespread in Europe mosquito becomes slow at low water development time. In this type, the larvae can survive for a long time in moist soil, but the adult animals are then smaller than in normal development. The females can travel per day distances up to one kilometer, overall they have a range of at least ten kilometers. Under favorable conditions, they can spread rapidly over a large area.
