Almost all insects have interesting ways of caring for their young, but few of them show as much skill as the wasps. Some wasps build little houses of mud for their babies. Others make nests of paper. Some dig caves in the earth, and some saw out little cells in wood.

When the house is built, each mother goes out to hunt for food to stock the house. Young wasps are very particular about their diet. Some will eat only spiders, some beetles, some flies, and many of them will eat nothing but living food.
