Species family information

Although Bush-crickets and Grasshoppers are related, there are distinct differences between the two families. Crickets stridulate by rubbing their wings together at dusk, their 'ears' being on their front legs. (In contrast, Grasshoppers stridulate by rubbing their hind legs against their wings, their 'ears' being at the base of their abdomen.) Whereas Grasshoppers are mostly herbivores, Crickets are omnivores. Bush-crickets have long, thin antennae (in contrast to the shorter, stockier ones that Grasshoppers have). The members of the Grasshopper and Locust family have short, stout antennae and the sound producing tympana membranes on the side of the first abdominal segment. The back legs have three segments. They have ridges along the top edge of the thorax, called keels, which are useful for identification. Grasshoppers have a three stage life-cycle, egg, nymph (going through five moulting instar phases, during which the wings gradually develop), and adult, when final wing development occurs. The most notorious members of this family are the locusts, although these are only rarely found in Britain. We have a photograph-filled blog post about all the grasshoppers and bush-crickets that we have seen in the Cemetery that may be worth your time.

Category information

Insects evolved in the Ordovician from a crustacean ancestral lineage as terrestrial invertebrates with six legs (the Hexapoda). This was the time when terrestrial plants first appeared. In the Devonian some insects developed wings and flight, the first animals to do so. An early flying group was the Odonata from the Carboniferous, the damselflies and dragonflies, which have densely-veined wings and long, ten-segmented bodies. They are day-flying carnivores, with an aquatic larval stage, so are commonly seen flying near water. The carnivorous larvae are called nymphs. Odonata species are short-lived, damselflies surviving for 2-4 weeks, dragonflies for up to 2 months.

Some insect groups in the Cretaceous co-evolved with the flowering plants, and they have had a close association ever since. These groups are the Hymenoptera (bees, wasps, and ants), the Lepidoptera (butterflies and moths), the Diptera (flies), and the Coleoptera (beetles). The diversity of beetles is astonishing. Of all the known animal species on the planet, one in five is a beetle!
