| Mason bees | | ...re loners (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 t... | | |

Adult robber flies’ ways of living are as varied as their biodiversity. Robber flies can be encountered in different habitats, from forests to sandy areas.
Less is known about their larvae They live in soil or in the woods and, like the adult flies, feed on other insects and their larvae (mainly on scarab beetles’ larvae, or on the larvae of beetles which live in wood). The larval stage takes 1-2 years before the larvae pupate.

The females lay their white, oblong eggs on plants in disorderly piles. Their larvae are whitish-green. They live in the soil and feed on rotting parts of plants and small organisms, which they kill by injecting them with poison, using their mouth parts.
Tabanus sudeticus are considered to be disease carriers, particularly of the EIA virus.

| The caterpillar is green. It has a dark stripe on its upper surface. The last segment bears the forked tail. The meadow brown is found almost everywhere, but is rare above 1600 metres.
Eggs are laid on the soil or on grass. The caterpillars shed their skin twice. They overwinter and pupate in May. The cocoon is spun on a blade of grass and is yellowish-green. The next adult meadow browns emerge in June.
The meadow brown is active from June to September... | | |

The fertilized females of Anomoia purmunda lay their eggs in holes bored into the fruit of hawthorn. The larvae develop in the fruit and feed on it. In autumn they pupate and overwinter in the soil. | | |
|
| The young ants overwinter twice in the nest which is built in the dead wood of trees and located up to three metres in height. The major part of the nest is under the soil. Some nests are only in the ground. After reaching sexual maturity, the young ants swarm from the nests on warm afternoons in May and June New colonies can be founded either by individual queens or by several Queens. In the latter case the eggs o... | | |

| The larvae suck the juices from leaf stems and leaves. In a later stage of development they swop to flowers and grass seeds. The larvae become adults from July on and overwinter in soil, leaf litter or dry grass. | | |
|
| The hawthorn shield bug reproduces once a year. The females lay their eggs on hawthorn shrubs. The larvae hatch in June and after shedding their skin five times, reach maturity in August. The adult bugs overwinter on the soil. | | |
