…trudes. Although the butterfly mosquito is small and with relatively large wings, it is poor at flying. When it moves, this happens in a bouncing and soft manner- or simply just by wandering around. At rest, the wings are held over the body like a roof. Biology and behavior Butterfly mosquitoes lay up to 100 eggs. The small eggs are oval, white, and long, but measures only 0.2 mm. The indoor species of the butterfly mosquitoes, Psychoda, usually l…

…s in attics, conservatories, stables, and places where they can be indoors without close contact with people. The reason why they are found in these places is that there are also a lot of other insects from whom they can suck blood. But also, because those places often are dark, which the dust mite prefers. The dust mite can live without food for a long time – up to several months. If you find a dust mite in your bedroom or other rooms, it is ofte…

…t about the dust lice and their reproduction is, that the eggs can develop without fertilization, which means that males do not have to be present. The dust lice development from egg to adult, is through nymph stages. This means that the development does not change that much, as the first stages of the dust lice resembles the last stages of their life. The only thing that does change is their size and a bit their color. Once the dust lice have hat…

…they are not flying. The flour moth can be recognized by its colors on the wings. The forewings have a lead gray color with a pattern. The pattern is zigzag with transverse lines and dots. The hind wings are a lighter shade of gray with fringes on the trailing edge. A larva from a flour moth is typically between 15 and 19 mm, so relatively short compared to the adult moth. An interesting thing about the larvae is that they can have different color…

…the yellow-brown body with two dark stripes on the back shield. The cover wings cover the flying wings, but it seldomly happens that the German Cockroach uses their wings. Biology and behavior A German cockroach typically belongs in a warmer climate than in Denmark, and therefore they are also dependent on being able to find warm places to live. Cockroaches eat everything and they are especially active during the night. In the light hours, they h…

…as two sets of wings. Only the rear set is used for flying. The top set of wings are the so-called cover wings. They have a special function. When the males rub the cover wings against each other, it produces a special song. A song that, among other things, should have an appealing effect on the house cricket females. The females have a long laying tube. Biology and behavior The house crickets are dependent on warm temperatures. They can easily st…

…hich she can repeat several times. However, egg laying does not take place without some difficulty. For the female needs to suck blood from a bird between each laying. For non-laying red mites, the need for blood meals is not nearly as great and they can easily survive for 4 to 5 months without blood. The process from egg to adult red mite is over quite quickly. And during the warm summer months, development can take place in as little as 8 to 10…

…he outermost layer, which is the most nutritious. The larvae eat the layer without at the same time gnawing through the surface of the wood. After this, the larvae gnaw further inwards, but no further than to the very core of the pine tree, which they cannot digest. There are many factors that come into play in relation to the larval development process. Under normal circumstances, the development from egg to adult beetle will last between two to…

…s gray-brown with a characteristic black spot in the middle of each of the wings. The male is light gray with dark zigzag bands on the forewings. The larvae of the bumble bee wax moth have a buttery yellow color, while their head is reddish brown. The adult larvae can grow up to 27 millimeters long. Biology and behavior It is not without reason that “bumble bee” is included in the name of the moth. For the larvae are often found in bumble bee beeh…

…rent species of mosquitoes. Midges, like mosquitoes, have wings, and these wings lies flat over their backs when the midges rest. Some species of midges have beautiful spots on their wings, although these spots will be difficult for humans to see. One will typically see female midges as only the females are bloodsuckers however the females and males looks like each other. Biology and behavior Midges likes humid and warm weather, so you they are ac…

…mpletely helpless. After 4 to 5 weeks, the young bat begins to train their wings and take their first flights. The cubs are a little insecure at first, but quickly begin to master the technique. At this stage, it is not uncommon for the little bat to get a little lost and possibly fly in through an open window. The mating of bats takes place in late summer and autumn. After mating, the sperm cells remain alive in the female’s uterus while she goes…

…ark, and they are similar in shape. Haematopota pluvialis has soot-colored wings and is smaller. Haematopota pluvialis are especially often seen on humid summer days. However, another type of horsefly, the Chrysops relictus has brown and spotted wings as well as yellow markings on the hind body. Biology and behavior There is a big difference in how the individual species of horseflies can look. Likewise, they can also behave very differently, as s…

…its search for a good place to pupate, the larva can cause chaos. It can, without hesitation, gnaw its way into woodwork, cardboard boxes, or the like. In workshops and warehouses, the Dermestes Lardarius can therefore pose a great risk of damage, as it can destroy crops or equipment. In houses, the Dermestes Lardarius can also do damage. However, not to the same extent as in, for instance, seed or feed stores. If a Dermestes Lardarius shows up i…

…to see with the naked eye, which is why they can easily breed in our foods without us noticing it. Prevention and pest control Prevention is without a doubt a great tool when it comes to banana flies. The banana fly is likely to be attracted from far away, and it is important to minimize all areas that can have an attractive effect on the banana flies. You can advantageously store your food in a way, that minimize the banana fly’s opportunity to l…

…e species consists only of females. The reproduction therefore takes place without the help of males, as the female is laying unfertilized eggs that develop into larvae. This form of reproduction is called parthenogenetic. The larvae have a few weeks to hatch if they have good conditions. They then go through the stage between larvae to adult clans, which last a year or more. In the household, the American dermestidae will often take up residence…

…ase A hungry tick crawls up grass straw or similar. Here, the tick can sit without moving for up to a week while waiting for an animal to pass. When an animal passes by, the tick is transferred on to the animal. Hereafter the tick finds a suitable place on the skin, where the skin is thin, and places its mouth parts inside the skin. Normally, neither bite nor bloodsucking is something people can feel. However, one should be aware that ticks can tr…

…ough the head can appear as lighter in color. The tail is also dark brown. Without the tail, an average Water vole is 12-22 cm long. The tail is between 5 – 11 cm long. Water vole can weigh up to 200 grams. There is no visible difference on the male and female water vole. Biology and behavior In the past, they were mainly found in wet and damp terrain. They are extremely skilled swimmers, but in recent time, they have been found in drier terrain….
