Invasive Arten in Brandenburg: Asiatischer Marienkäfer verdrängt heimische Art
Zurzeit tummeln sich viele Marienkäfer in Brandenburg. Der heimische, leuchtend rote Marienkäfer wird aber immer seltener. Stattdessen vermehren sich invasive Arten. Schuld daran ist der Mensch.
Noch nicht ausgewachsen: Der asiatische Harlekin-Marienkäfer kommt heute nicht mehr nur in seinem ursprünglichen Verbreitungsgebiet in Japan und China vor, sondern nahezu weltweit. Auch in Brandenburg drohen die Tiere die heimischen Marienkäfer zu verdrängen.
