Bee-fly Bombylius major along the Oak path 26th April 2013

Bee-fly Bombylius major hovering. This is a harmless fly and the sting-like projection at the front is part of the mouthpart which it uses to probe nectar from flowers. Something similar to the way a humming bird feeds.

The picture above - a body close up shows two club shapes organs which are replacing the second pair of wings lost in evolution.

 

 In two winged flies (Diptera) the halteres provide a means of encoding body rotations of yaw, roll and pitch during flight. This enables the insect to make corrections to enable a smooth flight.

CULICINE MOSQUITO Larvae and Pupa. Culicine mosquito larvae hang down from

the surface water film by means of a breathing tube. The pupa is between the two larvae.

Pictured left on the head of a Spear thistle is an uncommon species of Tephritid fly - a female Terellia serratulae. Its larvae cause galls on thistle heads. Seen in the picture is the short ovipositor used to deposit eggs into the thistle flower head. Thanks to Del Smith Dipterologist recorder for the Essex Field Club for identification.   23rd July 2013

The Glittering Green flies  Poecilobothrus nobilitatus are seen walking over liquid mud at Sheepwater. They show a metallic green in certain light. A male (top left in far left photo) is flapping his wings to attract the females feeding here. The wings are large with a brown patch and a white tip. The larger the wings, the larger the male,  making it more attractive to a female. Shown left  - a male has been selected and attempts to mate. Glittering Green flies.   .
