At three stages in the life cycle there This is a classical example of how life tables can be used to describe and understand population fluctuations over time. Adults are on wing from October to December. After a fly larva hatches inside a caterpillar, it lodges in the caterpillar's salivary gland and waits for it to pupate in the soil. In recent studies, it has been argued that sunspot activity forces the Epirrita autumnata 9-10-year outbreak periodicity in the mountain birch forest of Fennoscandia.
