The web is built among goldenrod or other high herbs, in open sunny fields, meadows or flower gardens.
This is an annual species; males are mature in July and August and females from August to October. Eggs are laid in autumn and the sac is papery, round and suspended among fallen leaves. Young winter in the cocoon and emerge in the spring (Dondale et al., 2003).

Observation: I have a yard full of these! I love them, so beautiful. I had 6, two of them have disappeared. Left behind a jumble of web and leaves. Babies? I have woods surrounding my backyard, they love it.
Two ladies at my inlaws, one is in an old horse feed dish laying on it's side, the other in an old calf feed trough. Both have laid 2 sacs this year. At last observance, one of the ladies looked fat enough to lay a third.
Will post pictures when I get them developed.
