Speckled Wood - Pararge aegeria


The appearance of this butterfly changes from the north to the south, forming a "cline", where individuals in the north are dark brown with white spots, whilst those in more southerly locations are dark brown with orange spots.

Identification difficulty

As its names suggests, this butterfly is primarily found in woodland but can be found anywhere there is sufficient scrub to provide the shaded conditions that this butterfly favours and this includes habitats such as gardens and hedgerows.

When to see it

April to October.

Life History

This species is unique among the butterflies of the British Isles in that it can over-winter in two stages, as both a larva and pupa. As a result, there is a mixed emergence with adult butterflies on the wing from April through to September, with a few adults being seen as early as March or as late as October, especially at southern sites. There are two or three generations, depending on location and weather conditions and adults of later generations are generally darker than those emerging earlier in the year. The larval food plants are grasses.
