The flea and the bugs

The flea and the bugs

In the past few weeks, the city’s environment department has received several reports of strange "moving pests" on trees, especially on linden trees, has been reported, for example from the kunigundenschule or from the schildstrabe. Jurgen gerdes, biologist at the environmental office, has meanwhile identified these coverts as coarse-flat bug colonies. He was surprised by their appearance in bamberg, because the mallow bug, also called linden bug, is a mediterranean species. It appears only since 2004 north of the alps, especially in warm regions in the rhine valley. According to gerdes in the press release from the town hall, this group of insects is also showing a tendency to spread northward from species in the mediterranean region, as has long been observed with dragonflies and butterflies.

In summer, when the mallow bugs suck on plants, they hardly appear at all. The overwintering mass accumulations on sunny stems and branches of lime trees are remarkable. The trees are not damaged by this, in contrast to human exhaust fumes and soil compaction.

Harmless for humans

The biologist gives the all-clear: for humans the bugs are harmless. They do not carry diseases nor are they domestic pests. He asks for tolerance for these already harmless animals with reference to a word by goethe: "the flea and the bugs are also part of the whole.".
