Wasps are relatively small animals. The larger wasp vespa crabro grows to a maximum of 2.5 cm long, but the typical size for smaller species is 1.2 to 1.4 cm. The worker wasps are typically between 11-15 mm long. The queen is somewhat larger and can grow between 14-19 mm long…

In social wasps, as in many bees and ants, the characteristic feature is a division of labour within the colony. Among the wasps the queens and males are occupied with reproduction while the workers build the nest, feed the larvae and defend the colony. Worker wasps are actually females…

Damage There are no parasitic wasp species that can damage furniture or houses. In fact, a variety of the species are used for biological pest control on farms, in plantations, gardens and greenhouses. Some species can sting with the laying brood, but this rarely happens. If this happens, it is usua…
Greater weevers
Fig. 100. Weevers. (Zool.Dan.) Greater weevers, Trachinus draco, can get up to 40 cm long and lives mainly in the North Sea and the Kattegat.

The chalcid larva lives as a parasite on the beetle larva and eventually kills it. There are records of up to 95 per cent of the beetle larvae in roof timbers being attacked in this way. When the adult chalcids emerge they often find their way out through the old exit-holes of beetle larvae or…

wasp and hornets A wasp uses its sting for killing prey, but it can also use it very effectively as a defensive weapon. The sting has associated glands which produce venom.
