Last week the third spider egg hatched in my kitchen window. Today the fourth egg hatched. The tiny spiderlings hang around the egg case for two or three days, and then suddenly they are gone. A few of them have made it into the house, but I think most find some little crevice to hide from larger, hungry creatures.
I was surprised that the eggs hatched so quickly. I had expected them to wait until spring. I have learned so much by letting this spider have her home outside my window, even though it is a bit gruesome and pretty grungy looking.
