| Both males and females have red and black markings on the abdomen. In the females these markings can be divided into three basic patterns according to their shape and location.
In type 1, which is themost common, the 2nd - 6th segments are red. A black line runs along the centre of these segments, which widens into a patch at the end of each of them. This black line is followed by a thin, yellow ring. All remaining segments are entirely black.
Type 2 has a similar pattern. However, the black markings on the 2nd - 6th segments are less pronounced.
Type 3, however, only has a slight red colouration on the sides of the 2nd – 6th segments. The rest of the abdomen has a black, metallic sheen.
Males only ever have distinct black markings at the top of the 7th - 9th segments. | | |
| Male Omocestus rufipes reach body lengths of 12-17 mm, females 18-24 mm. The males are always darker than the females. The females usually have black brown, greyish brown to yellowish-brown or very occasionally reddish brown sides with shiny green backs, while the males have dark brown to black sides with yellowish brown backs.
The underside of the body of both sexes is (moving from front to rear) first green, then yellow then red. This colour change constitutes the most important identifying characteristic of the species.

The underside of the body of both sexes is (moving from front to rear) first green, then yellow then red. This colour change constitutes the most important identifying characteristic of the species.
The front side of the head is black to blackish brown in both sexes. The colouration of the crown of the head corresponds to that of the back in both sexes. The antennae are black and have lighter tips. The maxillary and labial palpi are dark and also have lighter tips.
The thorax is black. The first segments of the abdomen are black The tip of the male’s abdomen is bright crimson. The wings go back as far as the hind knees and are mottled in the middle. The top halves are very dark. Due to their appearance, Omocestus rufipes can be confused with other species of grasshoppers. | | |
| | | Adult Myathropa florea reach body lengths of 10 - 14 mm. Their antennae are black, their eyes are hairy, and their faces have black vertical stripes. The abdomen is black with large yellow spots on the sides. The legs have yellowish and black markings and the wings are brownish in colour.

| | ...f the first generation (spring) reach wingspans of up to 38 mm, those of the second generation (summer) reach 43 mm, while the males can reach spans of 32 mm in spring and 38 mm in summer. The body of the butterfly is slim and the upper surface is a black-brown colour. The underside is lighter and slightly hairy. The rings on the segments are white. The upper surface of the wings in the spring generation is a brownish-red to orange colour and is interspersed with black patches. The summer generation are black-brown to black or sometimes blue-black) The undersides of the wings in the two generations differ only slightly. | | |
| | The basic color of the half ceiling is red. In its middle is a circular black spot and another, smaller, at the approach of the mid ceilings. The clavus and the membrane's approach are black. The markers and the abdomen are also black, the latter has a red outline. Legs, antennae and head are black. The inner edges of the half blankets together with the bottom of the neck shield do frame a black surface in the form of an equilateral triangle. | | |
| | The small tortoiseshell can reach wingspans of 40 - 50 mm. The base colour of the wings’ upper surface is orange. The front edge of the forewing bears a pattern of black, yellow and white patches with 1 large and 2 small black spots in the middle. The underside of the wings is black and has markings in different greys and grey-brown colours. The hind wings only bear a black patch. Both pairs of wings, have a pattern of black at the edge.

Beside each outer stripe is one more black stripe which is much thinner and only half as long. The yellow swarming fly’s wings are transparent and extend far beyond the end of its abdomen in resting position. The wings are well developed, unlike those of other frit fly species. The halter...

...ry. At the rear edge of the scutellum areoften a number of curved spikes, hence the family name "soldier flies". Their halteres are whitish in colour, their legs are long and yellow and their feet are dark. The abdomen of the murky-legged black legionnaire appears flattened.
The murky-legged black legionnaire lives in humid forests or in forest edges. It can be seen in early summer on sunlit leaves, flying, or sitting in bushes, hedges or other flowering plants, where it feeds on pollen and nectar and sometimes also on the substrate of rott...
...flying, or sitting in bushes, hedges or other flowering plants, where it feeds on pollen and nectar and sometimes also on the substrate of rotten plants. It can be found occasionally at dung heaps and also lives in other habitats. The murky-legged black legionnaire is defenseless against its enemies, as are all soldier flies.
Females lay eggs individually on rotting plants. In this humid environment, the larvae develop. Their bodies are uniform in shape, flattened and tapered at the end. They... | | |
