| Adult Syritta pipiens reach body lengths of 7 - 9 mm. Their bodies are club-shaped. In the males, there is an orange spot on both sides of the 2nd and 3rd abdominal segments; the females have silver-grey spots. Their femurs are very thick. Since their proboscises are very slim, they can fit inside even the smallest flowers. | | |
|
| The thick-legged hoverfly is common in almost all habitats, gardens, meadows, fields, however it is rare in forests. The females feed on pollen while the males eat nectar. The larvae (rat-tailed maggots) live in compost, manure and waste. The adult flies are active from April to September. | | |
|
| The tawny mining bee is not a social insect. The females build solitary nests (solitary bees), which can often be found in close proximity to others of the same species. Under favourable conditions 50 nests can occur in an area of one square metre. | | |
|
| Adult Andrena fulva reach body lengths of 8-14 mm, the females being smaller than the males. Their bodies have a black base colour. From March, bright auburn hair begins to grow on the chest (thorax) and abdomen. The colouration varies, up to May, from golden to straw yellow. The undersides of the head and bo... | | |
|
| The females lay their eggs on rotting plants, under bark or in reeds, using a special ovipositor which enables them to bore holes. After hatching, the larvae feed initially on the surrounding plant substrates. In a later stage of their development they prey on... | | |
|
| Flat-footed flies are small and reach body lengths of 2-3 mm. Their often compact and bumpy bodies are black or yellow in colour. Males are often darker than females. | | |
|
| Flat-footed flies feed on organic deposits on the leaves of trees and herbage. The females commonly lay their eggs on tree fungi. Oviposition also occurs on dead or decaying wood. The hatching larvae then feed on these materials. The larvae reach body lengths of 4-5 mm. Their yellowish to brown bodies resemble woodlice in shape and ... | | |

| ...ult Sepsis fulgens is usually dark, with a metallic sheen and 2-4 mm in length. The abdomen is roundish with a "wasp waist" at the front and altogether the bodyresembles that of an ant. The wings (males’ 1.8 to 3.3 mm in length, females’ 2.7 to 3.4 mm ), are completely transparent with a dark spot at the top. Males can be distinguished by the shape of their front legs. Adult flies give off a peculiar smell.

| ...the vicinity of their winter habitats for next year. In extreme cases, several hundred thousand can gather. In spring, after overwintering, the flies meet up at the marked places. Male Sepsis fulgens usually then visit dung-heaps where they await females for mating. The mating takes place at another location later on.
The female flies lay their eggs on dung-heaps or compost heaps. From the first or second day after hatching, the larvae begin feeding on feces or rotting parts of plants. At th... | | |
|
| The females lay their eggs directly on the excrement, or more rarely on decaying plant parts, where the substrate serves as a nutrient medium for the larvae who hatch one to two days later. The larvae go through 3 stages of development before they pupate. Pupa... | | |
