Wasp beetle

…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…

Wasps

…. 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…

Woodwasps

…lack with yellow or reddish stripes, as we know it from the classic bee or wasp. The wasps lay eggs, which subsequently develop into larvae that can grow up to 4 centimeters long. 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…

Wasps

…d the same habits. The wasps usually seen in or near houses are the 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…

Parasitic wasps

…e others choose to parasitize on aphids. Females from the larger parasitic wasp species, choose to parasitize on wood wasp larvae or butterfly larvae. 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…

…that recognisable waist. The only problem is that there are other kinds of wasps like wood wasps, sawflies and many more. If you want to be accurate, you use the name hornet on the social species that belong to the family Vespidae. We have seven species of social, community-forming, hornets in Northern Europe. They are very similar and live the same kind of life. Only the big hornet Vespa crabro, that is twice as large as its relatives, stand out….

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…

Wasps

Latin: Vespoides spp. Hornets – wasps Season 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 nes…

Other wasps

…e, but some species can inflict non-serious stings. Identification, however, is rarely a problem because the sting is clearly felt, so the culprit is identified. A larger species, the orange-red ophionl wasp, is an example of an ichneumon fly, which is attracted to light often strays into houses. It can inflict a painful sting with its short stinger if you accidentally squeeze it….

Clytus arietis

…le Clytus arietis With its eye-catching drawing and restless behavior, the wasp beetle corresponds well to its name. The larvae of this beetle live in dead, dry deciduous wood. 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

(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. 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…

Bees, wasps and ants

…ow, clear wings, and the hind wings are smaller than the fore wings. Bees, wasps and ants have slender waists in the front of the abdomen. They have “wasp waists”. 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…

White-shouldered house moth

…als also often tolerate them because they are not a danger to the birds or wasps. 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…

Bumble bee wax moth

…mble bee wax moth can make itself comfortable. They also like to settle in wasp nests or bird nests. In rare cases, they may even seek out a honeycomb. Inside the bumblebees’ nest, the bumble bee wax moth lives on the organic material found, such as the content of flower dust in the wax pots. 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…

Control

Fig. 50. When a wasp is not flying, the wings are folded together lengthwise so they are quite narrow. (Chinery) If you know where the nest is, you can move around the house without making the hornets nervous see, you can live with a wasp’s nest in the house or garden. In many cases, it is impractical; especially there are children in the house. Then eradication is necessary. A free-hanging hive can be neutralized by spraying an insecticide conta…

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…

Aphomia sociella

…is is a moth which lays its eggs in a bumble bee nest, or more rarely in a wasp nest. Bee moth, Aphomia sociella There the larvae feed on any organic material, e.g. the wax cells and their con- tent of nectar and pollen in a bumble bee colony, but they may also attack the bee larvae. When fully grown the moth larvae leave the nest in a body and in a sheltered spot nearby they then spin a communal cocoon, which may contain hundreds of pupae. The bu…

Ants

…prox. 100 million years ago, Ants (Formicidae) evolved from small solitary wasp-like ancestors. Some ants still have an actual venomous stinger like wasps. These stinging ants may attack if you accidentally sit on an anthill. Fig. 53 An ant spraying formic acid (Maschwitz) There is usually no doubt about what the problem is. An anthill in the lawn can be eradicated by saturating the hill with a diazinon solution. The ants which occasionally turn u…

They are circular, with completely smooth edges, and look as though they had been bored with a 10 mm drill. Wood wasps occur only in conifers, the larval tunnels being made in both sapwood and heartwood. The coarse wood dust is so tightly packed that it may be difficult to scrape out of the tunnels (see p.142). Saw flies…

Ants

…ales (flying ants) are produced during the summer. The males are small and wasp-like, the females – the queens to be- are up to 1 cm long. The winged ants seek towards light, they must be out in the wild to mate so you will find them on window sills and crawling in the curtains. This swarming takes place simultaneously from many communities in the area. The winged ants mingle with garden ants from other communities and mate. The synchronisation is…

Frequency

In the long term the frequency of the different animals change. Animals like the European adder, human fleas, dog fleas, bed bugs and body lice are no longer as common as they were in the past. Head lice have had three common periods in Denmark in the 1900s – During th…
