House Crab Spider Philodromus dispar
In autumn especially the House Crab Spider is regularly found on or even inside houses or other buildings. Usually it measures around 5 mm. It can be seen from early spring (April) through autumn (October). Living of flies and other small insects it lives in low vegetation and open spots therein and is especially keen on grasses. The females (below) are brown with distinct markings, the males are almost entirely black. In Britain this is a common species in England and Southern Wales. But it has a vast territory and can be found in most of Europe, Northern Asia and has been introduced in the USA, where it is now well established. In one of the pictures it is sitting near a Birch Catkin Bug, but the two showed no interest in oneanother.
