The surface of the thorax is yellowish, reddish and whitish in colour and has a wide, somewhat darkened median stripe, in which a bright line runs lengthwise. The scutellum (small triangular plate on the thorax) is bright turquoise. Each segment of the abdomen has a light brown andreddish brown pattern on it and a long shiny green stripe lengthwise on the upper surface. In male specimens the posterior part is often red or... | | |
| | ...eneration leave the soil in early May and lay their eggs, in June, on the leaves of different plants, such as cherry, pear, juneberry, mountain ash, hawthorn, quince, birch or roses. They scratch into the leaf tissue with their ovipositor, forming a small pocket in which a single egg is deposited. After 2 weeks, the larvae hatch and crawl sluggishly on top of the leaf and eat the tissue under scraping. They skeletonize individual leaf parts without the venation (ribs, leaf veins) and the lower epider... | | |
| | | Pear Sawflies usually only occur in small numbers. En masse, larvae of the 2nd generation can cause significant damage to fruit trees. | | |
| | The small to medium-sized Tephritidae have wings with striking markings. They have both compound and simple eyes. The females have a tubular organ (ovipositor) on the abdomen with which they insert their eggs directly in plants and fruits. | | |
| | The life span of the adults is often only a few days. The larvae live within almost all parts of plants. Some species inject their eggs into plant leaves on which a small ball grows with the eggs inside, other species live parasitically in the implantations of other insects. | | |
| | ...er mating, the fertilized females lay their eggs in the nests of different bee and waspspecies, for example Heriades truncorum and Ancistrocerustrifasciatus. Occasionally, oviposition takes place in butterfly cocoons, as observed in the case of the small tortoiseshell (Nymphalis urticae). Usually one egg is placed in each nest. Egg-laying often takes place in the nests of solitary bees of the genera Hylaeus and Osmia. A few days later the larvae hatch from their eggs. Firstly they eat the eggs or la... | | |
| | .... Their bodies are slimly built and usually orange or black. The head of this fly is relatively broad and they have bright red compound eyes. The 3rd antennal segment is short and ovoid. The antennae are inclined downwards from the 2nd segment on. A small triangle of ocelli (simple eyes) can be seen on the upper half of the forehead. Orbital bristles reach from the front edge of the eyes to the edge of the forehead. The upper surface of the chest (thorax) is brownish-black in colour and also has bris... | | |

The width of the body, at the 6th or 7th segment, is about 8 mm. The encrusted ocelli are at the front of the relatively small head. The antennae consist of 7 segments. The larvae overwinter twice in water and leave those on a plant stem, 2 to 3 years after they have hatched from their eggs. The new generation of black-lined skimmers hatch at the end of May. | | |
| | The large red damselfly has wing spans of 40 - 70 mm. Their pterostigma and the markings on their legs are solid black. Due to their external appearance, the large red damselfly can be confused with the small red damselfly (Ceriagrion tenellum). The latter, however, has red legs. Confusion with Pyrrhosoma elisabethae is also possible. Here differentiation is possible on the basis of the abdominal appandixes. | | |

Male specimens of two-tailed pasha guard their territory and fend off competitors from the same species. Occasionally, they even scare away small birds. Two generations of two-tailed pasha are active from May to June and from August to September. | | |
