Comparing Sounds, Structures, and Living Environments: Grasshoppers vs. Crickets
In the world of insects, two of the most intriguing creatures are crickets and grasshoppers. Both are known for their distinctive sounds and agile movements, but a closer look reveals significant differences between these fascinating creatures.
Crickets, belonging to the suborder Ensifera, are smaller and more compact than their counterparts, the grasshoppers. They are found in various families, including the true crickets (Gryllidae), mole crickets (Gryllotalpidae), and bush crickets (Tettigoniidae). On the other hand, grasshoppers, part of the Caelifera suborder, are easily recognisable by their long hind legs, designed for powerful jumps. They primarily belong to the Acrididae family, commonly known as short-horned grasshoppers.
One of the most noticeable differences between crickets and grasshoppers is their sound-producing behaviour. Crickets, particularly field crickets and tree crickets, are famous for their chirping noise, which they create by rubbing their front wings together. In contrast, grasshoppers produce sounds by rubbing their hind legs against their wings.
Crickets and many bush crickets exhibit sound-producing behaviour to attract mates, with sound production most active at night. Interestingly, grasshoppers are primarily herbivores, feeding on leaves, stems, and grasses, while crickets have a more varied diet, eating plants, fungi, and other insects.
Mole crickets, a distinct family from most crickets and grasshoppers, burrow underground using their front legs like shovels. They are not related to bats, as no bat species belongs to the family Gryllotalpidae. Wood crickets forage at night under leaf litter.
Grasshoppers, on the other hand, are not known for burrowing. Instead, they are often found hopping around fields and meadows. Some grasshopper species, like the meadow grasshopper and migratory locust, produce sounds, but they are not as well-known for their chirping as crickets.
The oak bush cricket and great green bush cricket are examples of the diverse world of crickets. Crickets and grasshoppers follow the same developmental pattern, going through incomplete metamorphosis from egg to nymph to adult, with no pupal stage.
In the dark, damp environments of caves, cave crickets can be found, often wingless. These creatures, like many other aspects of crickets and grasshoppers, continue to fascinate scientists and nature enthusiasts alike.
