Information

NERC Act S41: Not listed
Local status: Primarily a migrant, arriving from North Africa, the Continent or even Scandanavia during spring and summer. Numbers vary each year.
It breeds here, but in the main does not over-winter here, though during mild winters some do survive through to the spring.
Size: Large.
Larval foodplant: Common Nettle
No. of broods: Certainly one here, possibly more, but hard to say due to continuous immigration.
Flight time(s): Migrants begin to arrive in late May and can continue to arrive throughout summer. Individuals bred from immigrants begin flying from about early July. (Egg to adult takes only 6 weeks).
Winter: Some emigrate in autumn, a few hibernate and others die. A few may survive in any of the life stages. During mild winters over-wintering adults may be seen flying on warm days.
Habits: Ivy flowers are a favourite in the autumn. Quite difficult to approach. Larvae are solitary and live in a distinctive tent formed from folded nettles leaves.
Habitats: Anywhere nectar or nettles can be found.
