Then better not visit the "Hafen City" in Hamburg, Germany. Especially not the latest metro station "Elbbrücken" there, and especially not at night, because then they come out to hunt all the other insects which are caught in their nets, which they build over or near any light. Even over the touch screens of the ticket machines. They seem to be E-V-E-R-Y-W-H-E-R-E! BRRR!
