Through ignorance we often persecute our best friends. The ichneumon fly is a parasitic insect that all should know. It lays its eggs in the larvæ of many injurious insects, and its larvæ feeds upon them. A great enemy to the horned-tails, it is invariably misjudged and killed, when discovered with its ovipositor inserted in one of the borings of the horned-tail fly.
