The larvae hatch immediately They feed on dead organic material and algae. At the end of the larval period the males of the new generation leave the banks and fly into forests, while the females remain close to the water. | | |
| | Mayflies always live near water. Their life expectancy ranges from a few minutes to a few days. The females lay their eggs on standing or flowing fresh water. The newly hatched larvae breathe through tracheal gills. They feed on algae, plant parts and tiny crabs. Larval development usually takes 1 year, but can take up to 3 years depending on the specie... | | |
| | | The Pear Sawfly prefers habitats such as forests and gardens. Depending on the weather, it produces 2 or 3 new generations a year. Reproduction is normally parthenogenetic (without males). The females of the spring generation 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 ovipos... | | |
| | 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 adult wasps are mainly found on umbelliferae flowers, mint, thistle or golden rod plants. The larvae mostly live as parasites in the nests of some kinds of bees or wasps, e.g. digger wasps or solitary wasps. The fertilized females lay their eggs in spring in the nests of their larvae’s hosts. This happens near the brood’s site, which is equipped with food stores. The young Gasteruption larvae hatch after a few days and start eating the host’s eggs or larvae. Later they fe... | | |
| | After 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 ur... | | |
| | Females sometimes have two pins on the sides of the 4th segment of the abdomen, which can be retracted, and are possibly used as a stimulant during mating. The ovipositor is at the end of the female’s abdomen and has a telescope-like shape. There are also... | | |
| | Meiosimyza rorida are active from May to October in Central Europe, and prefer to live in the herb layers of deciduous forests, where they can be encountered moving slowly on leaves and stems. When disturbed, they hide. Females lay their eggs in rotting leaves, which the larvae feed on after hatching. | | |
| | After mating, the fertilized females lay their eggs at the base of grasses (Poaceae). After hatching, the maggots eat their way into and through the young sprouts and later feed on the young leaves of the grass plants. Further growth of such plants can be disrupted by this, or even pre... | | |
| | After mating, the fertilized females lay their eggs singly on bumblebees, ambushing the workers in flight. They cling to the host animal and lay their egg between the abdominal segments. The larvae hatch quickly and then eat their way into the abdomen of the host and hollow it out grad... | | |
