''Picture from Paranormal'' Animals of Europe
A '''Jauchekafer''' (''Lucanis fimus'', Jauchekäfer is German and means “sullage bug” in English) is a larged winged beetle, approximately 80 centimeters in length, that have infested all of the known habitats that consist of waste, filth and rot. Since they exist on most of the chemical and bacterial waste from metahumanity, most chemical and biological insecticides do absolutely nothing to them.
Chemical “triggers” can also cause unnatural aggressive behavior in the beetles, stimulating swarms of the bugs to attack anything nearby, which tends to be groups of metahumans. Since they live in the toxic waste of our cities and countries, their normal attacks can carry ill-fortuned side effects.
