Say’s Trig (Anaxipha exigua)

Song of a Say’s Trig (scroll down for explanation and additional recordings!).

Say’s TrigSmall and delicate, the Say’s Trig is a very handsome insect. This becomes more appartment if you inspect it with a magnifying lens and notice the head, which is decorated with a pattern of dark reddish brown bands set against light tan. Named after Thomas Say (1787–1834), who is often referred to as the father of American entomolgy. Say’s Trigs are found in tall grassy areas along roads and in fields. Honey locust trees are a favorite haunt as well. To find them, look for locust tress in weedy, grassy areas and carefully inspect the branches. You may be surprised to discover hundreds of Say’s Trigs residing in a single small tree.

Say’s Trig

Song: A clear, silvery trill at about 7 kHz that can be heard from a hundred or more feet away. The pusle rate is about 35– 40 per second. Males usually hide under a blade of grass when they sing. The song is so loud that it can be nearly impossible to exactly locate the singer, even when you’re very close. Using a sweep net is the best method for collecting them.
