Insect Order Hymenoptera - ants, bees, wasps, sawflies
Two pairs of membranous wings, venation often much reduced; the hind wings are smaller and connected to fore wings by a row of  hooklets; the mouthparts are primarily of biting type but often adapted for sucking fluids; the abdomen usually constricted at the base (except sawflies) with first segment fused to metathorax; ovipositor always present and modified for sawing, piercing or stinging; larvae usually legless with distinct head.
The Hymenoptera are divided into two suborders.
Symphyta (mainly sawflies and horntails) and Apocrita (wasps, ants, bees, and most parasitic forms)
