. Oxygen consumption (V̇O 2 ) in six species of adult tiger beetles Cicindela spp. (Coleoptera: Cicindelidae) was correlated with body mass and temperature during rest. In beetles forced to run and/or right themselves continuously for 5–10 min at 25°C, V̇O 2 was approximately 7–12 times as high as in resting individuals; the difference increased with increasing mass. Resting and active VO 2 were similar to previous results for other beetles, although the slope of log V̇O 2 on log mass was lower. Detailed analysis suggests the existence of taxonomic and ecological correlates of resting metabolism. The possible ecological implications and adaptive advantages of these results for adult tiger beetles are discussed.
