This little lady came io live on my window sill . Somehow she had lost a leg and was skinny. We watched her build a somewhat shabby web. I left the light on to help her trap some bugs. She got strength after a few weeks. Then I noticed she had gentleman caller. He stayed for dinner. Duh! Now she has gone and has left 2 egg sacks. Babies in the spring?
Yes. I believe they hatch in the Fall but stay in the sac and then emerge in the Spring. How lucky for you!
Then you probably know that these are Argiope aurantia, a very common orb weaver...
