Abstract

The cuticular hydrocarbons of four groups of grasshoppers were identified and quantified by capillary column gas-liquid chromatography (GLC) and GLC-mass spectrometry (GLC-MS), including samples of: 1) a modern species, M. sanguinipes (Fabricius), 2) a morphologically similar extinct species, M. spretus Walsh, 3) 650- year old fragments recovered from a receding glacier in southwestern Montana, and 4) 140-year old whole bodies from a glacier in northwestern Wyoming.
