Critically Endangered
Sardinian Green Bush-cricket
Tettigonia longispina
Sardinian Green Bush-cricket is a alasiwsiw.
The katydid
It was first described by Sigfrid Ingrisch in 1983.
Katydids are long-horned orthopterans. Most species sing from vegetation; a few are cave or ground specialists.
Grasshoppers, katydids, and crickets hear and sing. A species may be diagnosed by the song or by a mountain valley.
Range and habitat
Sardinian Green Bush-cricket is recorded from Italy.
GBIF currently lists 45 occurrence points. Those points follow where people logged the taxon — museum drawers and surveys included — not a closed range boundary.
Pins are Wikidata “endemic to” fields. Orange dots, when present, are GBIF occurrence tiles — survey bias included.
Habits
Katydids sing from shrubs or trees. Cave and ground forms in this family are the quiet exceptions.
Song, season, and a named mountain are how many of these insects were split. A silent valley after fire is an empty record.
