The bull weevil plays a key role in our ecosystem. As a dung beetle, it utilises dung and loosens the soil with its tunnelling skills. It is indispensable for our ecosystem, which has earned it the proud title of "Insect of the Year 2024". It utilises the faeces of herbivores, which greatly improves our soil. This happens both through the nutrients in the faeces themselves and through the tunnel passages that additionally aerate the soil. They spread plant seeds during their industrious work, they also reduce greenhouse gases and fewer flies and parasitic worms can develop. With a body length of 14 to 20 millimetres, the shiny black bull beetle is one of the larger beetle species in Germany. Its imposing "antlers" give the characteristic dung beetle its name. Only the male beetles have these three "horns". The females have a narrow keel and a small hump on the outside. The elytra have elongated dotted grooves.
Its digging legs are thorned so that it can dig tunnels easily. The bullfighter is widespread. It is found in North Africa, Western and Central Europe as far as the Baltic states. Its favourite habitat is sparse pine forests and heathland with sandy soil. The bull beetle is frequently encountered when walking in these areas. Like other coprophagous beetles, it feeds on the faeces of herbivorous animals and therefore plays a crucial role in our ecosystem. It also uses the sandy soil to build tunnels for its breeding chambers, which in turn aerate and loosen the soil. The reproduction of bull beetles is very interesting. After mating, they dig a two centimetre wide and 1.50 metre deep tunnel with several breeding chambers. In one chamber, faeces are formed into a pill, next to which the female then lays an egg. The hatching larva then feeds on the faecal pill. After about a year, development is complete and the adult, nocturnal beetles can go to work. Unfortunately, more and more habitat is being lost to the bull weevil. The use of deworming agents is fatal for the beetles, as they are not only poisonous for the grazing animals, but also for the faecal beetles. These products should therefore only be used when necessary. We would like to preserve this beetle, which is so important for our ecosystem. Our insect screens from Insektum also ensure the survival of insects by preventing them from entering our homes, where they usually die. We offer you high-quality insect screens customised to your needs for every window or patio door. We can also manufacture a suitable light well cover for your light wells.
