词条 | skipper |
释义 | skipper insect also called cheese skipper any member of a family of insects in the fly order, Diptera, in which the larvae are known for jumping or skipping when alarmed. The family name means “fat-loving,” and many species breed in fatty materials such as cheese and meat, where they can become serious pests. They also are found in decaying animal material; skipper species have been known to live in preserved human cadavers used in medical schools. Most skipper flies are tiny (about 5 mm 【0.2 inch】 long), shiny black in colour, and have long, fleshy mouthparts. lepidopteran ![]() Skippers are generally small, but their powerful wing muscles enable them to attain speeds up to 30 km (20 miles) per hour. Larvae feed on plants such as legumes and grasses and usually live inside folded or rolled leaves often woven together. Pupation occurs in thin cocoons of silk or silk and leaves. Many authorities do not classify certain skippers in the family Hesperiidae but separate them into the regent skipper family (Euschemonidae), which contains one Australian species, and the New World giant skipper family (Megathymidae), whose adults have a wingspan of about 9 cm (3.5 inches). The larvae, which bore in agaves and yuccas, are considered a delicacy in Mexico, where they are fried in deep fat, canned, and sold as gusanos de maguey. |
