…be found especially near flowers, but you can tell the difference between wasps and wasp beetles. Appearance A wasp beetle is also called a clytus arietis. They belong to the longhorn beetle family, which is also called cerambycidae. The wasp beetle can be recognized by its distinctive and sharp appearance. The wasp beetle can also be recognized by its black and yellow stripes that run across its elongated body. Similar to the animal it tries to…

…. There is a sting on the back of the body, and it is with this sting that wasps stick. Although wasps are considered to be very aggressive, they only sting as a last resort. 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…

A year in a wasp society In autumn a number of new queens and males are born in the nest. They swarm out and mate. Males die soon, but the fertilised young female wasps start looking for a reasonably sheltered place for them to spend winter. It may be in a hollow tree or a moss pillow, but often th…

…common wasp Vespula vulgaris, the German wasp, Vespula germanica, and the hornet Vespa erabro. 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 with undeveloped reproductive organs. Unlike the honey bee, wasps h…

The larvae are white yellow with three sets of breast feet, and at the tip of the hind body they have a short and dark thorn. Biology and behavior The appearance of this pest can be frightening to many and result in panic. Here, it is important knowing the difference bet…
Hornet stings
…tinger to remove. Because of its size and deep humming sound, the European hornet can seem threatening. Many feel that getting stung by this hornet equals certain death. However, it is not more venomous than its smaller relatives, but, naturally, it holds more venom. A rule of thumb is that a European Hornet sting corresponds to two of the smaller species’ sting. Moreover, most confrontations with hornets take place during the autumn when eating o…

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…
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…
Hornets (actual wasps)
Fig. 48. The German Wasp, Paravespula germanica. (Leclerq & Lecomte) Hornet, wasp In Denmark, there are seven species of social hornets. 6 of them are very similar to each other. They belong to the genera Paravespula and Dolichovespula while the species known as the European Hornet, Vespa crabo is more of a reddish yellow and twice the size of the others. Colloquially, they are often called wasps, however, this can create misunderstandings, as th…

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…

In many cases, it is impractical; especially there are children in the house. Then eradication is necessary.

They do not attack timber indoors, but may be introduced with logs, and when the adult beetles are flying in mid-summer, they sometimes come in through doors and windows. They attract attention because of the striking colour pattern, which is somewhat reminiscent of a wasp….
Wood wasps

It would, in fact, be possible to buy furniture containing these larvae. There is no risk of these insects spreading in the house, and it is very unlikely that they will be present in such numbers as to weaken the furniture. However, they may well cause damage w…

It allows the abdomen to move freely, and helps the animals when they sting. With the exception of most ants and a few bees, most of the hymenoptera females have stings. It consists of three needle- or blade-shaped parts. In some species, it is exclusively used as an ovipositor during t…

Damage Although white-shouldered house moth has been quite troublesome in the past, modern technology and development have made it more and more difficult for white-shouldered house moth and white-shouldered house moth larvae to survive in our homes. Since they require a humid indoor climate, and people most often try to minimize moisture in their homes, it simply be…

But the bumble bee wax moth also does not refrain from attacking the larvae themselves in the nest. When the moth larvae have finished their development in S…

The saliva may contain substances wh…
