Ecology. This species frequently occurred in the field. Plants affected by this species are Tritium aestivum (wheat), Oryza sativa (rice), Sacharum officinarium (sugarcane), and Echinochloa colonum (jungle rice). This species is hemimetabolous and moults 8-11 times to become adult (pers. obs.). Global distribution. Ukraine, France, Spain, USA, India, West Bengal, Kashmir, Pakistan, Mali ( Cigliano et al. 2020 ). Remarks. Gryllus bimaculatus is variable in size with colour variations. During this study we collected this species from dry parts of Nagarparkar and confirm its presence in dry barren areas. Chopard (1969) reported that G. (Gryllus) bimaculatus causes severe damage to potato plants.
