"The warmer, the more interesting for the insects"

WORLD: What is the reason for the swarming?

Hörren: In many species, these are pure mating flights. Some species wait for the hot summer days before even swarming. Various beetles actively migrate, sometimes hundreds of kilometers, and open up new habitats. Especially at these high temperatures one finds species that do not fit the habitats at all. They must have covered tens of kilometers in one night.

WORLD: How does it work with the light?

Hörren: The lighting system is operated with a 12 V battery and uses light spectra in the UV range. On the one hand, there are active light traps. The beetles fly against a window pane behind which UV light shines. They fall down and end up in a sample. This can also be used to quantify, they are preserved in alcohol and evaluated in the laboratory. On the other hand, we use the "lighthouse", which is a net-like structure with a lamp in the middle. The animals land on the net and can be observed. You have a colorful smorgasbord of insects in the light, which are very differently active.
