Two things are bad – that’s why there are so few wasps this year

Usually dozens of them buzz around a single sugar snail that lies at the bakery. Three more dozen can be found on the Mettbrötchen and the rest buzzes purposefully to the balconies of the people as soon as they want to enjoy their breakfast there in the still warm rays of sunshine on Sundays.

Last year it was normal. Only this year will the phenomenon of people thrashing around with their arms be largely eliminated. Reason: There are hardly any wasps.

Why? “There can be different reasons for this,” says Florian Lauer to BILD.

The expert for insect protection from WWF essentially explains two possibilities: “First of all, the longer and cold winter. This may have resulted in more wasp queens than in previous years frozen to death. “

“Afterwards we had a very cold and humid spring, this encourages mold growth and can lead to fungus growth in the queens and the fresh nests. With every queen who died in winter or spring, an entire state of the often several thousand individuals in the common and German wasp is lost in late summer and autumn, ”Lauer continues.

However, there are no solid scientific data on this, so it is very possible that there are other reasons for the low numbers of wasps.

Most people are happy about it. But does it also please nature?

Florian Lauer: “Nature is not happy about this. Each species has its job. You have to see the different species in nature as a spider web. They are connected to one another via many so-called interactions. If a species is weakened or if it is missing completely, the network is weakened. If too many are missing, it can even collapse. This then also has negative effects on people. “

So can’t we see wasps just as nuisances?

“Such a decline is more damaging for nature, since the wasps are a kind of cleaning crew and pest control”, explains Lauer. “A large state can capture several kilograms of insects within a week. These often include so-called pests such as aphids, mosquitoes and bedbugs. In addition to this task, wasps are also simply important food for a large number of other animals, including many species of birds. “

But anyone who now hopes that there will be so little buzzing and buzzing next year will be disappointed.

Lauer explains: “Wasps can easily buffer fluctuations in population size due to their high number of offspring (including sex animals). That means wasps have adapted to suffer high losses, which they then make up for with many offspring. But wasps and other insects are also reaching their limits due to habitat loss, insecticides and many other factors. We have to start to protect the insects more comprehensively, otherwise the whole spider web threatens to tear apart and with it our livelihood. “

That’s the best reason to endure the black and yellow sausage and jam thieves more benevolently.
