Studying life histories of insects

Cut large rectangular holes in the sides of a big cardboard container and cover them with muslin folded over at the edges and gummed or pasted into place. Make a big door by cutting along three sides of a rectangle and bending along the fourth side. Stick a tab of folded paper or cardboard to the front edge of the door to act as a handle. Leave the original bottom of the box intact, to give rigidity. (If cellophane is available a window can be made in the door or in single side of the box.) Put a loose piece of paper on the floor and stems and leaves of food plants. This is better than pots of water in which the insects might be drown
