berguna untuk diketahui

Fakta

After mating, the male may escape being eaten by living in the nest with the female for a time, but in other cases the female eats him.1

Its web has separate areas for nesting and for catching prey, and it also helps keep the spider cool by providing shade in summer.1

Its webs often include a funnel of silk decorated with debris, which may help hide the spider from predators such as birds flying overhead.1

The web's silk carries pheromones that help males find female nests.1

Its colour darkens after each moult, so the spider becomes darker as it grows older.1
