|Queens overwinter. They appear in March or April. Bombus pascuorum nest both above ground (old birdsí nests) and below ground (abandoned mice nests). The bees use moss, grass and animal hairs to construct a hollow sphere inside the nest. The interior of the hollow sphere is sealed with wax. The queen then forms a small tub of wax, puts pollen in it and then lays 5 to 15 eggs on the pollen. It also builds a second, slightly larger vessel for nectar (for food on rainy days) . In the period up to August the ...|
|This bug overwinters in the adult stage. It hides in fallen leaves, bark or in the hollow parts of plants. From May on the larvae hatch, which are green in colour and in July the adult stage is reached. The females lay their eggs on nettles on the upper side of the leaf stalks. Every year, a new generation emerges.|
|...rs (solitary bees) and belong to the family Megachilidae. Approximately 50 different species are found in Central Europe. These include Osmia bicornis and Osmia cornuta.
Mason bees build their nests in walls, cracks in stone, , (sandy) soil, hollow plants, dead wood from trees or in the galleries of wood-boring insects. The females build individual brood chambers inside the nest using glandular secretions and leaf pieces. ) They deposit pollen and nectar in each brood chamber for the futur...|
|...They often sit on the bare, hot sand waiting for their prey which they catch and sting in the air.
The dune robberfly is active from June to September. The females have a ring of spikes at the end of their ovipositors which they use to make a hollow in the sand to lay their eggs in. The larvae usually move deeper into the sand after hatching.|

Hylaeus reproduce either once or several times a year. The females lay their eggs in nests, which are constructed in hollow plant stems, dead wood or often in the galleries of beetles or other insects. After oviposition (egg laying) the nest is sealed. The larvae overwinter in the nests. Wasps of the family Gasteruptionidae are natural enemies of Hylaeus as their la...|
|...ps, or sometimes grasshoppers. They cling to the host animal and lay eggs between the segments of their abdomen. The hatching larvae then eat their way into the abdomen of the host animal, reside there and feed on the insides of the host until it is hollow. The larvae overwinter in the host insects. Some species, such as Conops flavipes (the most common species of the genus Conops) live in the nests of bees and bumblebees where their larvae feed on the bee brood.|
|... abdomen of the females is almost completely covered by their wings. The larvae of Chaoborus crystallinus are transparent (glass rods larvae) and horizontally live in water. They breathe through their body surface. In the 7th abdominal segment, are hollow sacs filled with air which keep the larvae suspended. These sacs can be filled with air or water to allow the larvae to rise or fall as required.|
|After mating, the females keep the sperm viable. They lay approximately 20 - 90 eggs in a hollow space. The hatched larvae are guarded by the females. The larvae shed their skin several times.|
|...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 gradually. Sicus ferrugineus larvae pupate and overwinter in the hosts. |
