The Avondale spider comes from the huntsman spider family. It got its name from a place called Avondale in Auckland. Some people also call it the social huntsman or flat huntsman spider. These spiders mostly live in Australia.

Eggs

Female Avondale spiders produce flat and oval egg sacs and subsequently lay around 200 eggs in them. Few spiders even make a silken base for the sac just before the egg-laying process and once all eggs are released, they carry the sac and discard the silken base. The egg sac is often carried by mother spiders.

Spiderlings

Young Avondale spiders come out of the eggs with a pale complexion. Sometimes, the mother spider moistens the egg sac and then tears it open to make the emergence of young spiders smooth and hassle-free. After coming out of the eggs, the spiderlings stay a few weeks with their mothers.
