The Speckled Wood (Pararge aegeria) is a butterfly found in the woodlands throughout much of Europe. It is brown and has pale yellow or cream spots and darker eyespots. The depth of color is variable with groups from some areas having brighter colors than in other areas. 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. The chrysalis is green or dark brown.
