Roesel's bush-cricket (Metrioptera roeseli)

Metrioptera roeseli - Roesel's bush-cricket Roesel's bush-cricket (Metrioptera roeseli) is a European bush-cricket

Roesel's bush-cricket adult is 15 - 18 mm long. It is brown with a very pale margin ('c' or 'u' shape) to the sides of the pronotum (saddle like structure behind head) this margin is entire, unlike its very close relative the bog bush-cricket.

Its forewings usually reach midway along its abdomen at rest. However there is a macropterous form of this insect (f. diluta), in which the wings reach beyond the tip of the abdomen. This form appears predominantly during hot summers and enables the species to extend its geographical range rapidly while conditions are suitable.

In Britain Metrioptera roeseli was formerly found only near coasts of southeast England but recently has spread further inland.
