The time needed for the juvenile flies to emerge can vary from 10 days at 25 °C to 80 days at 10 °C or less. The smaller females typically emerge a few days before the males. The fitness of the resulting juveniles is greatly dependent on the quality of the dung in which they were placed.
What causes phenotypic plasticity in yellow dung flies?
Much phenotypic plasticity in yellow dung flies is a result of food (dung) availability in the larval stage, which is often mediated by conspecific competition. Less dung results in more competitors, and more drying results in decreased growth rate and adult body size.
How long does it take for fly larvae to emerge?
