I am located in a large Eastern European city. During this summer, a new kind of bug has started appearing in my house (or more specifically, coming into my house from the garden). It's about 1.5-2 cm long, doesn't appear to have any wings, and a relatively strong exoskeleton (makes an audible crack when the bug is squished). Its favorite activities seem to be either sitting in the middle of the floor, waiting for someone to step on it, or sitting on the ceiling and then falling onto somebody's head. Whenever I see one of them, it's almost completely stationary, regardless of the time of day.
Here are pictures of it (sadly, they're very grainy due to my phone's camera's low quality).
