Speckled Wood

Description:

Females have brighter and more distinct markings than males. The wingspan of both males and females is 4–4.5 cm, although males tend to be slightly smaller than females. Males are highly territorial and will defend their territory against intruding males. Two basic strategies exist for finding females: some males will vigorously defend a perch and the immediate surroundings, waiting for females to pass by; others will patrol a larger territory.

Habitat:

is a butterfly found in and on the borders of woodland throughout much of the Palearctic ecozone.In North Europe, Central Europe, Asia Minor, Syria, Russia and Central Asia

Notes:

I think the specimen in the pictures is a male, since the color is not orange.
