As borboletas Grande Imperador têm um período de voo curto, de Abril a Maio, durantes o qual não se alimentam. Os machos voam rapidamente em busca de fêmeas. As fêmeas descansam durante o dia e atraem um grande número de machos. Após o acasalamento, as fêmeas voam ao início da noite para colocar os ovos em grupo em diferentes plantas arbustivas. As lagartas eclodem no final de Maio e inicialmente alimentam-se em grupo. Hibernam como pupa.

The adult emperor moths are only on the wing for a couple of months at the most, and during this time they do not feed. They appear in April and are day-flying, the males flying about rapidly in their search for females. Females rest during daytime and an un-mated female can attract a large number of males if she is found resting. Having mated, the females fly off in the early part of the night to lay their eggs in batches on a number of different species of plants. These include meadow sweet, heather, hawthorn, bramble and birch. The caterpillars hatch in late May and initially feed in groups. They overwinter as pupae.
