- The eggs hatch in Fall although the young spiders stay inside the sac over Winter, emerging the following Spring and reaching maturity in Summer.
- These spiders are harmless to humans.
- They are most active during the daytime, seen in sunny fields amongst plants and flowers but sometimes along the eaves of houses and outbuildings.
- The webs are circular, up to 2 feet across and have a distinctive zigzag of silk in the centre. The webs tend to be 2-8 feet off the ground.
