…a In recent years, long-tailed silverfish (ctenolepisma longicaudata) have been registered more and more frequently in the household. Long-tailed silverfish is related to the well-known silverfish, but as an adult is larger, has long tail wires and antennae as well as a clearer hair. There is also a big difference in how the two species behave in buildings. This is what long-tailed silverfish look like The long-tailed silverfish is a wingless inse…

Bumble bee wax moth
…included in the name of the moth. For the larvae are often found in bumble bee beehives. But a bumble bee beehive is just one in a series of nests where bumble 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. Bu…
Plasterer bee
…can be difficult for an ordinary person to distinguish between a plasterer bee and a honeybee, or a completely different kind of bee. Which type of species that just flown past one really do not matter unless it stings. The plaster bee is in general not aggressive, although they have a sting. In a completely normal situation, however, there is not much to be afraid of when one crosses path with a plaster bee. Appearance A plasterer bee simply look…
Mason bee
…noted that there is a big difference between the mason bees and plasterer bee. Mason bees build their own nests using brickwork, where plasterer bee dig their nests into the brickwork, and thereby damaging walls. Appearance Mason bees can be easily be confused with other species of bee. They have, like most bees, six legs, transparent wings that lie flat on their backs when resting, and of course feelers on their heads. The mason bees can vary in…
Bumblebee
…ecies prefer to build their nest in the ground, which includes the species bumblebee (Bombus lapidarius) and house bumblebee (Bombus hypnorum). The bumble bee is not picky about living conditions, and they may find themselves settling into everything from an abandoned mouse hole and small spaces in stone dikes to bird boxes and insulation materials in attics. It differs from species-to-species what types of beehive they prefer. Appearance The bumb…
Red-brown longhorn beetle
…ghorn beetle is 12-18 mm long and is characterized by the reddish brown or red colored cover wings. Color wise there are all kinds of variants. However, they have yellowish hair, which is characteristic for this species. In general, the females are larger than the male which can be surprising to some people. The female is also more robust in her appearance, while the male is seeming slimmer. This is the easiest way to distinguish the females from…
Red mite
…ssume a more black or grayish color. During long periods without food, the red mite even becomes almost completely whitish. The adult red mites, like other types of mites, have 4 sets of legs. The mite is also equipped with two sets of mouth parts. The mite’s so-called upper jaws have the shape of a pair of pointed stilettos. It is these jaws that the red mite uses to stab its victim and suck blood. Biology and behavior The red mites are active no…
Bumble bees
Bumblebee, tree bumblebee Unlike the honey bees, in which the whole colony survives the winter, a bumble bee colony only lasts for a single season. This means that all the workers die in the autumn, so that only a few young mated queens survive and spend the winter in hibernation. The bumble bees seen in March flying low over the ground are usually these young queens, just emerged from their winter quarters, and now searching for suitable places…
Honeybees
…without reason that the concept of “diligent as a bee” exists. Because the bees are incredibly hardworking. But the extent of the work that a bee does depends on the age of the bee. And the bee will go through several phases of the work in the colony, as it gets older. In its first days of life, a newly hatched worker bee will spend its time cleaning the nest. The bee then goes through a period in which its work tasks consist of tending and feedin…
Bee stings
…hrough breeding they have become extremely peaceful. The notorious “killer bees” (Africanized honey bees) are a crossing between European bees and an African species that was bred in South America in order to have a more sturdy and active bee. Unfortunately, they are also very aggressive and difficult to deal with, but stories that they seek out and attack animals and humans are exaggerated. What to do about the sting? The stinger should be remove…
Honey bee
…ey bees as pollinators cannot be overestimated, and their honey has always been much sought after. Honey bees live in colonies with a highly developed social organization, which go on from one year to the next. Each colony consists of a queen, a small number of males or drones, and a large number of workers, perhaps 10,000 to 20,000. As the central figure in the colony the queen is continuously fed and tended by• the workers, as she concentrates o…
The red-legged ham beetle
Latin: Necrobia rufipes. Also called copra beetle. The red-legged kopra beetle The red-legged ham beetle is 4-5 mm long, dark metallic blue with reddish legs. The larvae are up to 10 mm long. They are light grey, but with clear violet drawings on the upper side. In the rear, they have two dark spots. This species is cosmopolitan, probably mainly spread through the trade of copra. Moreover, the larvae develop in many different products: cheese, dr…

…e abrupt transition between the third and fourth antenna links of the rust-red flour beetle. The confused flour beetle has a smooth transition between the antenna links. The biology of the two species exhibits only small differences, but the differences are still significant enough to determine that one of the two species is successful while the other performs poorly in our climate. According to British statistics, the rust-red flour beetle is tha…

…Latin: Necrobia ruficollis. The red-breasted kopra beetle The red-breasted copra beetle is metallic blue with a red chest and red on the front of the wing covers. It is widespread across the world. In this country, it is in particular related to companies working with meat and bone meal….
Mining bees
…ion, some of them are more hairy, so you could confuse them with very thin bumblebees. However, by far the fewest Danes have an eye that is trained to see the difference between honeybees and the many different species of mining bees. One can mainly see the difference between mining bees and other bees in their behavior. However, one should no matter what treat a mining bee as one would a treat an ordinary honeybee, as their impact on nature and h…
The rust-red grain beetle
The rust-red grain beetle Season for rust-red grain beetle Latin: Cryptolestes ferrugineus or Laemophloeus f. The genus Cryptolestes is a complex of several species that are all very similar to each other. They can all occur in grains, bran, flour and the like, often in very large numbers. The rust-red grain beetle is 2 mm long and it is uni-coloured. The sides of the head and the prothorax are lined with one plain line. In grain storages it occu…

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 buttery yellow larvae of the bee moth crawl on the litter’s common web of pupa cocoons. They have gnawed their way into a white foam sheet These are com…
Mason bee
…tin: Osmia bicornis) Mason bee, Osmia bicornis This is one of the solitary bees in which the nest is built of mud, in a wide variety of sites. On occasions the nest may be constructed indoors, possibly behind panelling, in furniture or even in a key-hole, provided there is constant access to the outside world. Apart from the fact that it may sometimes block a lock with mud this is a completely harmless species. Mason bee cells with pollen and larv…
Red poultry mite
Red Poultry Mite (Latin:Dermanyssus gallinae) When filled with blood this mite has a beautiful red colour. Gradually as the blood is digested the mite becomes a little smaller and the colour changes to grey or blackish, and if it has fasted for a long period it is almost white. The poultry mite lives in henhouses, in dovecotes and similar places, where it remains hidden in crevices during the day. At night it emerges to suck blood. The female lay…
Ham beetle
…e, but it is red on the chest (which can also be seen on the “back” of the beetle). This reddish color is also found on the front of the ham beetle’s cover wings. Finally, we have the blue ham beetle, also called Necrobia violocea. The blue ham beetle has a full-colored, uniform bluish tone, and this beetle is the only one that is apparently not a pest. So, you can guess the danger by looking at the color. All three species of ham beetles can fly…
Rat-tailed maggots
Latin: Eristalis sp. and Helophilus sp. Technically, Rat-tailed maggots are not a species. Rat-tail maggots are a term for larvae of hoverflies or drone flies. Hoverflies are also called Syrphidae, but overall, they are the two families Eristalis and Helophilus, when talking about rat-tail maggots. Rat-tail maggots, of course, got their name due to their appearance, which may resemble a rat tail. Rat-tail maggots may be disgusting animals, but th…

Usually, they are both seen and felt. The bite wounds may itch a little. As far as we know, the red mite is not a transmitter of diseases. Changes color Adults red mites are 1 mm long, flat and have 8 legs. Right after a blood meal, the mites are beautifully red. As the blo…
Red-legged copra beetle
( Latin: Necrobia rufipes) Red-legged copra beetle This beetle has spread to most parts of the world owing to the trade in copra (dried coconut). Apart from copra it also eats carrion and like the larder beetle it will thrive in parts that are too dry for other carrion-eaters. It can also live on museum specimens, and has been found, for example, in Egyptian mummies. In factories and warehouses it attacks concentrated fodder, fish and bone meal,…

Temperature-wise, it prefers a few degrees more and is accordingly to this the more common of the two species in tropical regions. In the temperate parts of the world it is not as common as the confused flour beetle. With a monthly multiplication rate at about 70, it holds the record of the insects in th…

Glass wool used for insulation might not appear to be a very suitable material for nests but in spite of this, mice and rats will gnaw tunnels through it and construct their nests in it, thus reducing its effectiveness as an insulator. Bumble bees may also establish them- selves in insulating material, but the damage done will be local and not very serious. When tufts of insulating material appear under the eaves it will normal…
