Title: Cryptic coloration and choice of escape microhabitats by grasshoppers (Orthoptera: Acrididae)

Abstract: Cryptic coloration is found in many Orthoptera, especially in Acrididae, showing a great variety of forms. In a grasshopper assemblage in southeastern Brazil, preferences for escape places were detected; grasshoppers tended to escape to backgrounds in which they seem to be more cryptic. Coloration was measured using the Simpson diversity index, to quantify 'aspect diversity' (diversity of colours and shapes of patches along the insect's body). A weak positive correlation was found between grasshoppers' aspect diversity and diversification in use of escape places (use of many backgrounds to escape). Grasshoppers xith similar colour patterns tended to use the same structures (leaves, sandy soil, stones) to escape. (C) 1997 The Linnean Society of London.
