Description

Wing span: 60 - 74 mm

One of the first butterflies to be seen in the spring, the Brimstone is also one of the longest-lived in its adult form, with some individuals living for 10 or 11 months.

It is mainly found in England. In Ireland it is only common in the Burren.

It can be found anywhere that the larval foodplant grows, which is usually damp woodland.

The main flight periods are March to June, then a second generation flies from late July to October or November, before entering hibernation.

The primary larval foodplants are Purging Buckthorn (Rhamnus catharticus) and Alder Buckthorn (Frangula alnus).

Favourite nectar sources are Thistles, Knapweeds, Scabious and Teasels.

Male Brimstones can be found well away from breeding sites, often being seen on road verges and hedgerows.

This species is of Least Concern on the UK list.
