This species overwinters as young larvae, feeding mainly on Oak, Alder, Hazel and other deciduous trees. Adults are partially predatory and feed on caterpillars and other insects as well as on fruits. Eggs are laid in August. Adult Forest bugs can sometimes be found in the early Spring, which suggests that a secondary breeding cycle may be possible.
