More open areas have a good variety of insects including the small copper butterfly and Roesel's bush-cricket.

Its song bears a strong resemblance to that of Roesel's Bush-cricket.

Roesel's bush-cricket is native to the United Kingdom.

Despite being native to Europe, Roesel's bush-cricket has made its way into North America.

Invertebrate species include the scarce Roesel's bush-cricket.

Roesel's bush-cricket is commonly found throughout southern and central Europe, as well as further North, in Finland, Latvia and Sweden.

Roesel's bush-cricket (Metrioptera roeseli) is a European bush-cricket, named after August Johann Rösel von Rosenhof, a German entomologist.

This orthopteran fauna is believed to be the richest in Hertfordshire and includes several species more associated with coastal sites, such as the lesser marsh grasshopper and the nationally scarce roesel's bush-cricket.

Notable Irish species include the freshwater pearl mussel, diving bell spider, Marsh Fritillary Butterfly, Kerry slug, Semilimax pyrenaicus, freshwater crayfish, the White Prominent moth, and Roesel's bush-cricket.

It has been forecasted that Roesel's bush-cricket will disperse even further across eastern Canada and the United States, more likely limited to areas where grasslands are left relatively untouched across the year so as to allow the eggs to hatch.
