Dintlha

1

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

2

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

3

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

4

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
