  abstract = {{I}ncreasing the ecological relevance of studies relating to the performance of organisms has been a central issue for functional biologists over the last few years. {O}f particular concern are changes in performance throughout the life cycle as selective forces act differently on various life stages. {W}e addressed this issue experimentally by following ontogenic variations in the escape performance of crickets threatened by artificial predatory signals. {W}e measured their performance under natural settings, which is a necessary approach yet one that is undocumented in insects. {W}e analysed numeric film sequences obtained using a high-speed video camera at 1000 frames s(-1) to quantify wild cricket performance and behaviour in the field. {W}e detected significant differences in cricket escape performance throughout ontogeny. {E}scape performances were higher in juvenile crickets than older instars. {C}omplementary behavioural measurements for escaping crickets suggest that these variations may be related to the lower predatory risk perceived by large adults than by juveniles. {W}e expect that our analysis of size-refuge will also improve our understanding in the development of performance, given its importance in community and population ecology theories.},
