One of the - a commonest bristletails is the little shiny fish-moth, which annoys housekeepers by getting into starched clothes, among books, papers, etc. It is about half an inch long, with long antennae and three bristles extending half the length of the body from the tip of the abdomen, and is covered with silvery scales which glisten as it darts around in a book- case or drawer, reminding one of a fish's scales flashing in the sunlight. They are very soft-bodied little insects, more abundant in warm climates, and feed on starchy matter or soft paper. In some species of bristletails the bris- tles have been modified into forcep- like appendages. Most bristletails are much smaller than the fish- moth, and are found beneath stones, logs, and loose bark, and FIG. 89. The pond-sur- similar situ- face sPrinstail (Smyn-. FIG. 88.
