The photographs immediately above and below were taken on our property in northern Indiana, and depict a Say's Trig (Anaxipha exigua), which was named for early American entomologist and naturalist Thomas Say. Say's Trigs can often be found in large numbers on woody vegetation in grassy areas. An identifying characteristic of this species is the dark stripe on the light-colored face. Although they are small (approximately 1/4 inch long), Say's Trigs are extremely loud and can be heard from over 100 feet away.
One of my favorite singing insects so far is the Handsome Trig (Phyllopalpus pulchellus). As you can see below, it sure is a handsome insect... just look at those contrasting colors! For an excellent description of this species, just translate the Latin name. Pulchellus is translated as "beautiful," and Phyllopalpus means "leaf-feeler." The Handsome Trig, also known as the Red-headed Bush Cricket, uses its palps (the fingerlike appendages near the mouth) to investigate its surroundings. These palps also vibrate rapidly when the insect is threatened. This species is another tiny insect (1/4 - 1/3 inch) that produces an enormous sound. I photographed this Handsome Trig near Logansport, Indiana.
