Candlefly. Among the smaller fire-flies which twinkle all the year rushes, in the summer months, the great Candlefly. It makes a roaring sound with its strong, swift flight, and is a strange and splendid object. It has three lights, two looking like eyes, and a larger and much more brilliant one underneath the thorax. When at rest only the eye lights shine, but with the spread of its wings a shutter is drawn back and discloses the abdominal light. The insect, which is the size of a cockchafer but rather longer, is commonly called Big Winky or Peeny.
