Abstract
We examined the relationship between developmental stress and fluctuating asymmetry in a natural population of Drosophila pachea, a cactophilic fruitfly. Cactus host variation was found to exert significant influence on the size of legs and of wings of emerging adults, but stressors associated with reduced size did not show the predicted increase in fluctuating asymmetry for either leg or wing length. These findings underscore questions raised by other investigators as to the broad utility of fluctuating asymmetry as a measure of environmental stress
