Cave crickets (Family Rhaphidophoridae) often live in perpetual darkness and have particularly impressive antennae, which are many times longer than the body. Many grasshoppers are day-active, whereas crickets and bush-crickets tend to be more active in the evening and at night (with some exceptions), so using their antennae to sense their surroundings may be more important. This could in part relate to the time of day that they are active. Crickets and relatives have more than 30, while grasshoppers and relatives have fewer. The number of segments in the antennae also differs.

Grasshoppers vs crickets: Antennae A pretty meadow grasshopper (Chorthippus parallelus) © Getty Images You can spot the difference by looking at antennae length and segmentation, diet, song production, mating position, egg-laying tactics and the unusual placement of the ears. What's the difference between a cricket and a grasshopper? This branch includes the world’s heaviest insect: the giant weta (Genus: Deinacrida) of New Zealand. The ‘cricket’ branch includes true crickets, scaly crickets, mole crickets, ant-crickets (which are adapted to live in ant nests), bush-crickets (or katydids), leaf-rolling crickets and wetas. The branch to which true grasshoppers belong also contains groundhoppers, monkey-grasshoppers, stick-grasshoppers (which are superficially stick-insect like), gaudy grasshoppers and bladder grasshoppers. Each branch contains a fascinating assortment of insects. How do insects fly? The miracles of insect flight revealedĬrickets, however, are thought to have split from grasshoppers before the age of the dinosaurs, at least 250 million years ago the two groups belong to very distinct branches within the order Orthoptera.Sea insects: why are there so few insects in the ocean?.Most species also use sound as part of their mating behaviour and share a life-cycle in which the newly hatched individual looks like a miniature version of the adult, but without the wings. These include back legs modified for jumping, ‘primitive’ biting mouthparts and slightly hardened forewings, which act as covers for the transparent, fan-like hind-wings. Members of the order Orthoptera have certain things in common. Technically speaking, they are both members of the same insect order: the Orthoptera. Before considering the differences, it is best to start with the similarities. One question that I’m often asked is: ‘What is the difference between a cricket and a grasshopper’. ![]() My encounter with an enormous adult female great green bush-cricket ( Tettigonia viridissima) while on holiday in Devon as a teenager cemented my fascination with them, a fascination that I have been lucky enough to develop as part of my career. ![]() Grasshoppers vs crickets: what's the difference between these two jumping insects?Ĭrickets, bush-crickets and grasshoppers have been favourites of mine since early childhood.
