Electric Light Bug, our largest bug. So named from its habit of dashing at electric lights. It is an aquatic bug, and is properly called the giant waterbug. It lives on minnows, small frogs, tadpoles, and the like, which it holds with its front legs while it sucks out the blood. The waterbug sticks the tip of his abdomen out of the water to breathe, as its breathing spiracles, corresponding to nostrils, are, insect fashion, situated along the sides of the last segment of the body. An interesting feature is the peculiar construction of the front leg, the second joint of which shuts into a groove in the upper joint like a blade into the handle of a knife. At night waterbugs often come up out of rivers and ponds and fly about, being particularly attracted by street lamps; but, no accident preventing, they are back in the water by dawn of day.
