My first time seeing one of these impossibly cute and tiny bugs - probably 8mm long and not happy about my presence. in Germany it’s called the “Büffelzikade” which means Buffalo cicada, but it isn't really a cicada. It's scientific name is Stictocephala bisonia or sometimes Ceresa bisonia. Was so lucky to find it and that it was patient before finally flying away to safer ground.
Was difficult capturing this with my phone. Maybe 1/4 inch big. Moved quickly and smoothly, was very aware. Shiny, you can see the reflection of my red umbrella in one photo.
