French Jura: Orthoptera

July 17-21, 2012:
Much of this area of central France is rich in Orthoptera, especially crickets and grasshoppers. Most grassland and even roadside verges have a large number of individuals, often with a range of species represented. Sub-alpine grassland at the Foret du Risoux was particularly rich. Altogether, at least eight species of grasshopper and four species of cricket were seen and photographed during a five-day period of warm sunny weather. These are shown below.

An adult female Upland Green Bush-cricket (Tettigonia cantans) which is a relative of the Great Green Bush-cricket found in southern England but with broader more rounded wings - Lac de Bellefontaine. A male nymph is shown below.
