…pletely dead and hangs back as nothing but a hollow shell. The problem for wasps (hornets) in these latitudes is that they do not, like the honey bees, store food for the cold months, and then must start fresh every spring. Wasps rarely occur as pests and in most cases you can live harmoniously as neighbour to a wasp’s nest. But if you are allergic to their stings or they appear in large numbers in a nursery, or if there simply are so many that it…

…gement of the nest. Later in summer a successful wasp colony may hold 5.000-6.000 individuals. Wasps can often be seen sitting on fences or telephone poles gnawing the timber. They chew the fine wood splinters with their own saliva to form a superior paper with which they construct the nest, both the outer protective casing, which comes to resemble an oval football and also the hexagonal cells in which the larvae develop. The larvae have an exclus…

Wasps

…for wasps The wasp is a wide category that covers digger wasps, parasitic wasps, hornets etc. Wasps are well known in their black and yellow striped abdomens and no less for their ability to sting. In Northern Europe there are about a dozen species of social wasps, which are very similar to each other both in way of life and appearances. At our latitude wasp colonies are annual. This means that the nests are only used the year they are built. Old…

Wasps and hornets

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. A hornet sting can be very painful, but is normally not dangerous, as the amount of venom injected is very small. In some cases, however, people do become ill after being stung by a hornet. This is due either to the venom being injected directly into a blood vessel or to the v…

Chalcids

…lay their eggs through the timber with the help of their ovipositor. Sabre wasp, large ichnemon wasp bores it’s ovipositor into wood wasp larvae to lay egg. 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…

Wood wasps

(Latin: Family Siricidae) Wood wasp Great wood wasp Wood wasps only lay eggs in trees that still have their bark, so they are unlikely to enter a house, except in timber already infested. It would, in fact, be possible to buy furniture containing these larvae.
