![]() And some katydids look so much like leaves, complete with dried patches, chew marks, and holes, that you’ve probably walked right past them without realizing you’re being watched.Īnother group of cricket relatives, New Zealand’s wetas, includes enormous insects that can outweigh a mouse. Then there are the bush crickets, or katydids, which come in hot pink and other startling hues. To attract mates, they throw little rock concerts: They dig horn-shaped burrows, turning their homes into amplifiers that make their calls extra loud. These insects have big claws and live underground. One group of cricket relatives is the mole crickets. People also use the word cricket for many close Gryllidae relatives, and they’re an amazing bunch of insects. That’s just the so-called “true” crickets, members of the family Gryllidae. And if you visit the tropics, where there are more cricket species than anywhere else, you might spot this intricately patterned Nisitrus species. The snowy tree cricket is pastel green with wings shaped like tennis rackets. There’s the red-headed bush cricket, also known as the handsome trig-and it’s, well, pretty handsome for a cricket. But that somber insect has some pretty colorful relatives. If you’ve found a cricket in your house or yard, chances are that it’s black or brownish. They’re some of the smallest ears of any animal, but they’re highly sensitive. And cricket ears are tiny spots, just a fraction of a millimeter long, on their front legs just below the knees. When a butterfly lands and folds up its wings, it’s exposing its ears. Those cricket-eating parasitic flies, for example, have ears just below their head and neck. Those silent, safe crickets compensate for their lack of courtship songs by spending more time on the move, which improves their chances of running into potential mates. They’ve evolved wings more like a female cricket’s, which means they’ve lost the ability to chirp. Male crickets on Kauai have responded in a remarkable way. Those maggots burrow into their victim and devour it from the inside. Some crickets have evolved to stay silent.Ī particular fly species has invaded the island of Kauai in Hawaii, and it’s the stuff of cricket nightmares: It uses its incredibly sophisticated hearing system to find a singing cricket and drop maggots on it. The Old Farmer’s Almanac recommends that you count the number of chirps in 14 seconds and add 40 to get the temperature in Fahrenheit. The snowy tree cricket’s gentle calls seem to match the heat especially accurately. It’s such a proven phenomenon that you can use it to calculate the temperature. You can use cricket songs as a thermometer.Ĭrickets call more frequently when the weather gets hotter. Crickets also sing to intimidate rival males, and some of a male’s more romantic tunes may trigger nearby females to fight each other. Many of them have a whole repertoire of calls: There’s one for attracting females from afar, another for close-up courtship, and even a triumphal after-mating song. But crickets don’t just sing a pretty song and wait for the admirers to trickle in. So why do male crickets (usually) chirp? 4. And males of some cricket species never make a peep. There are exceptions: Some female mole crickets (relatives of “true” crickets) sing. Most female crickets lack those sound-making wing structures. That cricket in your house that’s endlessly chirping away? It’s probably a male. Scientists have even managed to recreate the sound of an extinct cricket relative, a fossilized Jurassic bush cricket (katydid), by examining the shape of its wings. ![]() They rub a scraping organ on one wing against a comb-like organ on the other.Įach cricket species has distinctive noise-making structures that produce unique sounds. Run your finger down the teeth of a comb and you’ll hear an almost musical rattle. There’s a persistent myth that crickets rub their legs together to make sound. How do crickets chirp? Old-timey illustrators sidestepped this question by drawing them playing tiny violins. They don't make sound the way you think they do. Interestingly, the name for the sport of cricket has a totally different origin: it comes from an Old French word for goal post. The word cricket comes from the Old French word criquet, and refers to the cricket’s song-people once thought that those repeated chirps sounded like “criquet … criquet … criquet.” Crickets were named for the sounds they make. Here are 11 surprising (and often adorable) facts about crickets. They’re living thermometers with ears on their knees, and they just might save the world. They’re insects that invade our homes, but they’re beloved around the world.
