The Speckled Wood (Pararge aegeria) is a butterfly found in and on the borders of woodlands throughout much of Europe. In Northern and Eastern Europe where subspecies P. a. tircis occurs it is brown with pale yellow or cream spots and darker eyespots. In southwestern Europe the subspecies P. a. aegeria has a colour which is more orange in the background. The two forms gradually intergrade into each other. The speckled wood also occurs in North Africa and on the Atlantic island of Madeira. Molecular studies suggest that the African and Madeiran populations are closely related and distinct from European populations of both subspecies, suggesting that Madeira was colonized from Africa and that the African population has a long history of isolation from European populations. 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. The caterpillar is green with a short, forked tail and feeds on various species of grass including Yorkshire Fog. The chrysalis (pupa) is green or dark brown. The species is unique in its ability to overwinter in two totally separated developmental stages, as pupae or as half-grown larvae. This leads to a complicated pattern of several adult flights. |
