The Sow Bug, commonly called the “Pill Bug,” is usually found hiding under a damp log. It is completely innocuous and will often roll into a ball when disturbed. [Illustration: Centipedes] Centipedes (Chilopoda) Elongated, segmented body Fifteen or more pairs of legs One pair of legs per segment The Centipede is usually found hidden in a moist place. It feeds on insects killed by a poison injected through its jaw. Although Centipedes occasionally bite a finger, their poison is so weak that the bite can be ignored. [Illustration: Millipedes] Millipedes (Diplopoda) Hard, segmented, worm-shaped body Two pair of legs per segment Roll into a ball when disturbed The Millipede is found in much the same habitat as the Centipede, under a board or rock or inside a rotten stump. It is harmless, and lives for the most part on decaying plants. INSECTS: SIX-LEGGED ANIMALS _The Mayflies_ [Illustration: Mayflies] These insects have long, soft bodies and two long “tails.” The first stage in the Mayfly’s life is spent under water in one of the several swampy pools behind the main beach. Early in the spring it changes into the winged adult that is unable to eat. This adult lays its eggs and dies soon afterwards. _The Dragonflies and Damselflies_ [Illustration: Dragonflies] Dragonflies (Aeshnidae, and others) Two pairs of long, stiff wings Two large compound eyes, which touch each other Hold wings outspread when they alight Dragonflies are often called “Devil’s Darning Needles,” but they are perfectly harmless. They frequent wet areas, where they feed on other insects—particularly mosquitoes! [Illustration: Damselflies] Damselflies (Lestidae and Coenagrionidae) Two pairs of long wings Large compound eyes do not touch Wings folded over back when resting Aside from their smaller, more delicate appearance, these insects look like the Dragonflies. They are found in the same places and have similar habits. _The Fan-winged Insects: Grasshoppers, Crickets, etc._ [Illustration: Short-horned Grasshoppers] Short-horned Grasshoppers (Acrididae) Antennae shorter than body Typical Grasshopper shape Most Grasshoppers are strong fliers and are easily frightened into flight. The males may be heard singing during the day—a rasping noise produced by drawing the hind leg across the veins on the wing.
