Crickets are found on the soil, hiding under dead plants or on live plants. They only occur where there is plant material to eat, and they are most diverse and abundant in humid areas with lots of plants. Most crickets can live for a year or more, but usually can't survive more than one winter. Male crickets chirp by rubbing their front wings together, as their wings have special structures for this.
• Crickets are medium-sized to large insects with larger, stronger back legs than the other two pair, and most are brown, although some are black or, in the case of tree crickets, are green with whitish wings.
• Unlike katydids, crickets often look flat, though they have rounded heads with long, thin antennae and wings bent down the sides of their bodies.
• Both males and females have ears, which are smooth round structures on their lower legs.
