I may be arrested for this, but I brought home a few praying mantis egg sacs from the fields of Valley Forge last fall. I've done this for the last several years. Shhhhhhhhh. I put them in a glass jar with a little saran wrap on top and punched little air holes so there would be good circulation. I put the jar on the window sill in the guest room. And today, as I went into the room to check on things - the jar was buzzing with about two hundred baby praying mantises. A few had already escaped through the air holes. I rescued them and took everybody outside, keeping them in the jar until they were ready for their release into the world and a little photo session. Here are a few of the little beauties.
