Phaeostigma notata


    The body length of this insect is about 15 mm. The antennae are long and slender. Like other snakeflies, Phaeostigma notata is able to raise its head above its body while resting. This motion is like that of a snake getting ready to strike. Adults have four wings that are clear and membranous. The wings are veined with a conspicuous spot. It is located on the front margins near the tips. While Phaeostigma notata is at rest, it holds the wings up rooflike over the back. Female snakeflies have a tail-like ovipositor which is used to lay eggs in bark crevices etc.
