Sexual Reproduction #1
Adult insects have one main purpose – to find mates and lay eggs. Because of their small size, insects rely on a variety of signals – scent, color, movement, light, sound or a combination of these – to meet the opposite sex. Many female moths release a scent orpheromoneinto the air that attracts males from great distances. A male giant silk moth has been known to travel as much as thirty miles to a female. The twinkling of fireflies on a summer night may seem random, but a female firefly, perched on a stem of grass, is on the alert for the particular pattern and color of flashes, at the right height in the sky, that identifies a male of her species. She sends out a reply flash and waits for him to alight. Mayfly males form swarms and perform a synchronized dance to attract females. In insects that chirp, orstridulate,like crickets, grasshoppers and katydids, the males sing to attract females. Crickets scrape the hard edge of one wing across a row of pegs on the other wing, while grasshoppers rub a wing against a row of pegs on their back legs, each species producing its own special song.
