oa Journal of the Entomological Society of Southern Africa - Ecological studies on solitary Acrididae in England and South Africa
Short-horned grasshoppers commonly occur in habitats of small extent, separated by different environments, and not constant for long periods. Colonisation of new suitable areas appears to be carried out by individuals frequently moving across non-suitable areas. Movement to suitable areas appears to be partly done by directive movements in response to visual stimuli, more probably to colour than to shadow.
