|Insects (Insecta) live almost everywhere on Earth. They are highly specialized and there are about 30 million different species. Insects can have body sizes from 0. 2 to 330 millimeters. What is common to all insects is the highly visible breakdown of the body into three parts: head, chest and abdomen; and the presence of three pairs of legs. |
|...lis arbustorum have antennae with feathered bristles. The scutellum is brown and the abdomen is black. The bottom edges of the segments of the abdomen are white. On the sides of the second segment of the female insect, reddish-yellow spots are visible which overlap onto the third segment on the body of the male insect.|
|Adult speckled bush-crickets reach body lengths of 10 - 15 mm. They have a saddle - shaped, strong body, on which yellow markings are more or less visible lengthwise. Speckled bush-crickets have very short wings, especially the females, whose crescent-shaped ovipositors curve downwards. The females lay their fertilized eggs separately from each another, the eggs overwinter and the larvae hatch in the ...|
|Adult Nephrotoma quadrifaria reach body lengths of 5 –15 mm. Their bodies are black and yellow in colour. The wings bear a clearly visible dark mark. Near the tip of their wings the veins are running across. |
|...ands which are a metallic-green or golden colour depending on the light. These bands usually have a brownish central area, which separately bears a black pattern. The rear wings of the burnished brass are brown. Tufts of rusty-brown hair are clearly visible on the upper surface of the chest. |
|They have black bristles on the central section of the chest and two fine dark, longitudinal lines are visible there. The common yellow dung fly has greyish-brown transparent wings with red to yellow edges at the front. The abdomen of the females is greyish-brown with black hair, while the abdomen of the male is light yellow in colour.
|The wings are transparent, sometimes with a brownish tint in the centre, and reach the end of the abdomen in resting position. The venation of the wings is clearly visible. |
|...ach body lengths of 7 - 10 mm. Their bodies are covered with shiny dark brown, reddish brown, grey, whitish yellow and ochre scales. Their heads are strikingly narrow and long and bear oval, greenish eyes. A thin, light, well-defined central line is visible on the pronotum; it runs across the joints of the wings, becoming darker and more extended. The front chest scaly before each hip with a vortex. On scutellum the scales radially stand off. The legs are not "toothed". |
|...mm. Their bodies are almost always black and hairless , which rules out immediate determination of Hylaeus species in the field. . Only three species have red as the base colour of their abdomens.
It is typical for all Hylaeus to have a clearly visible marking on their face, yellow or yellowish white in colour, but on the females this may be reduced to a few points at the sides or to narrow vertical stripes on the anterior eye margins , or this marking can be completely absent. The markings o...|
|The latter have transparent wings, while the former have wings with zigzagging dark stripes. Another typical characteristic is the marking on the upper surface of the abdomen. The several segments formed through yellow rings are clearly visible. The marking on the second segment resembles a chalice. The base of the hind femur is a yellowish colour. |
