A general term for insects in the Lepidoptera, Tortricidae family. Small to medium-sized moths with long, slender wings and often with sharply pointed forewings. The hind wings are generally trapezoidal and lack markings. There are beautiful species such as the velvet moth that have a wingspan of over 5cm, but generally most have a span of around 2cm and plain colors. Distributed worldwide, with over 500 species known in Japan. A small proportion are diurnal flying species, but most are nocturnal and often arrive at lights. The English name comes from the fact that many species, when stationary with their wings folded, resemble a bell. Source: Heibonsha World Encyclopedia, 2nd Edition Information |
