E. atra spiders live in a variety of habitats. This is because of their ability to travel long distances via ballooning. They are primarily found in grasslands, fallows, and crop fields. E. atra's colonial habitat is subject to variation based on season and other environmental factors. They prefer grasslands with high yields of vegetation and fewer populations of different species. E. atra prefer perennial grasslands over crops because perennial habitats are sustained over time. During the winters, E. atra prefer higher vegetation habitats as they provide more protection from predators and increased insulation from the cold. The increased canopy cover creates a dry shelter with ground vegetation which is required for overwintering. Some exchange between grassland and crop habitat exists during a spider's lifetime. E. atra can be found in regions where both cows and sheep graze. Combined grazing of cows and sheep create a uniform expanse of short grass which provides an ideal high-density, low-species habitat.
