Faktlar

The eyes are all the same size and sit in two rows. They contain few visual cells, so the spider can probably only tell light from dark.1

Until 2018, the giant house spider was treated as one species. Research then showed three separate species, which can only be told apart under a microscope.1

Males wander while searching for females during mating season, which runs from late summer into autumn. This is when they are most often noticed.1

Males have no Y chromosome. Males carry X1 and X2, and females carry two pairs of X chromosomes. This form of sex determination is the most common in spiders and is probably the ancestral form.1
