This little case is at first a sticky substance that soon hardens. The eggs lie in it side by side in two rows.
These cases remain attached to the abdomen of the female cockroach until the eggs are all laid. Then the case falls off, and soon out runs a crowd of infant cockroaches.
The case is something like a satchel that shuts with a spring. The youngsters are packed close together, side by side, with their heads towards the mouth of the satchel.
As soon as one hatches it pushes open the side of the case and creeps out. Then the case springs together again to protect the rest of the brood.
They are funny fellows when they first come out, little and white-looking. But they eat and grow of course, and shed their skins, and after each moult they become darker in color.
Now, do look again at this cockroach I have taken such pains to catch for you and put into the tumbler.
I think even May will own that it has a cunning little head.
See it turn its head around to look at us.
After all, the cockroach is a knowing little fellow.
