• The viability of eggs and newly hatched larvae of Luciola cruciata (Coleoptera) were investigated in terms of individual differences in egg size. The mean egg weight decreased with the aging of a female, and also decreased seasonally through the oviposition period. Heavy, middle and light eggs showed high hatchability at low, middle and high temperatures, respectively. When the eggs developed at a favourable temperature, they maximized their larval size and the tolerance of newly hatched larvae to starvation. Such phenomenon may be a physiological one but has been previously overlooked due to the rearing of such insects under uniform conditions. The different viability of eggs in relation to temperature seems to be well adapted to the changing temperatures experienced in the natural habitat and may maximize the survival value of all the eggs of an invdividual female owing to the decrease in egg size.
