An ecological survey of Acridoid grasshoppers (Orthoptera) in the Niger-Delta region of Nigeria

An ecological survey of acridoid grasshoppers was conducted in the Niger Delta region of Nigeria from January to November 2001. A total of 34 taxa distributed in 3 families, 12 sub-families and 27 genera were encountered. The family Acrididae had the highest number of species (28), followed by pygomorphidae with 5 species. The family Tetrigidae was represented by only one species. Several species showed ecological plasticity and were found in all the locations while many others showed ecological restriction.
