| ...urope bumblebees survive only one summer. Drones and workers have a life expectancy of 3 to 4 weeks, while a queen lives for approximately 1 year, during which time it hibernates for 8 months. There are, among bumblebees, socially parasitic species (Cuckoo bumblebees) which leave their eggs in the nests of fellows and let the fellows care for their breed. The larvae of the cuckoo bumblebees danger the fellows’ own breeds since they eat the eggs and larvae. These species have no workers. | | |
| | The cuckoo bee Nomada fucata lives parasitically in the nests of Andrena flavipes, smuggling its eggs in, and leaves its brood as well as their supply with nutrition to the hosts. It may happen that the cuckoo bee larvae eat all the host larvae’s food supplies so that the host larvae eventually starve. | | |
| | | Rubytail wasp | | The rubytail wasp (Chrysis ignita), is a species of the genus Chrysis, in the order Hymenoptera, the suborder Apocrita, the infraorder Aculeata, the superfamily Chrysidoidea, the family cuckoo wasps (Chrysididae), the subfamily Chrysidinae, and the tribe Chrysidini. Chrysis ignita are widespread in the Palaearctic ecozone of Europe and West Asia. In Central Europe, it is the most abundant species of cuckoo wasp. | | |
| | Common to all wasps is the black-and-yellow warning colour of the body. The Vespinae live in states or parasitically as so called cuckoo wasps. Adult Vespinae mainly feed on small parts of dead or living animals, from insects, pollen, plant juices and from nectars. Their larvae are mainly fed on animal meat.

Some species overwinter as larvae, others as adult mason bees. The latter are already active in March. The natural enemies of mason bees include the larvae of cuckoo beeswho feed on the eggs of the mason bees and their food stores.

Oviposition of the fertilized females takes place separately (in rarer cases in small groups) do you mean that the eggs are usually laid singly on the preferred food plants of the caterpillars, such as the cuckoo flower (Cardamine pratensis), bittercress (Cardamine amara), garlic mustard (Alliaria petiolata) and many different Brassicaceae (in former times: Cruciferae). From the latter the female orange tip clearly prefer dame’s rocket (Hesperis matronal... | | |
| | The Andrena vaga only collects nectar and pollen from pastureland. Other species only live on pollen from asparagus, Bryony or Potentilla.As brood parasites and nomada bees, the cuckoo bees lay their eggs into the nests of Andrena. Other parasites are the blister beetle, Bombyliidae and Strepsiptera.Andrena, like many wild bees, are of major ecological importance due to their role as plant pollinators. | | |
| | Bumblebees (as well as bees in general and flies) are among the most important crop pollinators. Some of the most important natural enemies of bumblebees are: Cuckoo bumblebees, Anthidium manicatum, Mutilla and thick-headed flies. | | |
