Last night, I discovered this early instar nymph of the cockroach Planuncus tingitanus s.l..🔦 It's a species complex which still needs much research. 🔬
Originally from the Mediterranean, they have spread rapidly in Europe in recent decades. In Germany, they were first found in Mainz in 2007. That's about 50 kilometers away from Oberursel. They live on shrubs near human settlements🌳🏘🏡 but only accidentally get into houses and only live outside.
