Fig. 93.—duagox-flv, of the air, and monarchs of the insect world. Yet in the earlier stages of their existence, these splendid creatures arrayed in humbler guise inhabited some neighbouring pool or ditch; the larva is an uncouth, broad, flat, olive- coloured animal, having six sprawling legs with which it crawls, spider-like, about the mud at the bottom of ponds, or glides by a singular mechanism through the water. The hinder extremity of the body is furnished with several leaf like appendages, capable of being brought close together or opened at pleasure. These close the orifice of a cavity whose sides are very muscular. When the insect wishes to move rapidly it opens this cavity, which thus becomes filled with water, and then by a con- traction of its walls the water is forcibly ejected in a stream, as from a syringe, and thus the larva is proj)elled through the water with its legs closely packed against its sides. The pupa only differs from the larva by having the rudiments of wings attached to its thorax; both are.
