In this analysis we studied, in laboratory conditions, the impact of warming and hatching dates on key life history and physiological traits in a cannibalistic damselfly, Ischnura elegans. Larvae were reared in groups from hatching to emergence through one or two growth seasons, depending on the voltinism. Larvae were equally divided by hatching dates (early and late) and temperature treatment (current and warming). Early and late hatched groups were not mixed. This data set includes: survival until emergence and emergence success data development time (from hatching to emergence, in days) mass of adult insects growth rate (mass of adult insect/development time in days) protein content (μg of protein/μl of prepared homogenate) phenoloxidase activity (PO, value of activity curve slope) PO activity/protein (value of activity curve slope/(μg of protein/μl of prepared homogenate) insects voltinism (univoltine/semivoltine)
