Giant housespider

Know more?

In some areas this species is being displaced by the Cardinal spider. This is one of the species of which adult males can be found in the bathtub. Males get stuck there while searching for females because they can’t climb the slippery walls of the tub. Some other spider can because they have “suction pads” on their feet!

Giant housespider (Eratigena atrica)

Web: Typical funnel web with a funnel-shaped retreat.

Habitat: In and around buildings, with a preference for sheltered, not too dry places. Often outdoors, far away from buildings, i.e. in hollow trees or on rocks.  

How to recognize:

  • typical light drawing on the abdomen and dark coloured drawing on cephalothorax
  • often a more dark appearance compared to the other two house spider species
  • legs never darkly annulated

Looks similar to:

  • Blackwalls house spider, from which the Giant house spider cannot be distinguished based on general appearance. Only through examining the reproductive structures is it possible to decisively identify species but this examination is not easy.
