Ensifera<\/strong><\/p>\n

The Ensifera, or long-horned grasshoppers (referring to their relatively long antennae), includes three families, the Gryllidae, the Tettigoniidae, and the Raphidophoridae, that you will see in this lab. Many insects in this suborder are cryptic. New species are being described all the time, especially from the tropics. There are some important economic pest insects in this group, but they can also be cultivated as food for humans and domestic animals including pets. There are about 40 species in BC.<\/p>\n
