A PICTORAL REVIEW OF
THE MAJOR INSECT ORDERS
~ Damselflies and Dragonflies.At rest, damselflies hold their wings together above the body or diverging; dragonflied hold them horizontal.
~ Grasshoppers, Crickets, and Cockroaches.Usually large insects; hing legs often (grasshoppers and crickets) enlarged; front wings narrow, hind wings broad and at rest folded fanwise.
~ True Bugs.Front wings thickened at base and membranous at the tip, the tips overlapping at rest; antennae 4- or 5-segmented; mouth parts in the form of a sucking beak.
~ Aprids, Hoppers, Cicadas, and Others.Piercing-sucking mouth parts; beak arises at rear of head.
~ Beetles.Usually hard-bodied insects, with front wings thickened and meeting in a straight line down back; antennae nearly always with 10 or more segments; mouth parts chewing.
~ Butterflies.Gaudy diurnal insects with scaled wings that are large in proportion to body; antennae knobbed but never hooked at tip, and close together at base; wings at rest often held together above body.
~ Moths.Nocturnal (rarely diurnal) Lepidoptera with antennae threadlike or feathery (not clubbed as in butterflied); at rest, wings usually held horizontal or rooflike over body.
~ Flies.With only 1 pair of wings (most other insects have 2 pairs).
~ Sawflies, Wasps, and Bees.Narrow waisted to a greater or lesser degree. Bees differ from wasps in being more hairy, with the body hairs branched, more robust, and the 1st segment of the hnd tarsi is usually elongated and flattened; two pairs of membranous wings.
