The common walkingstick or northern walkingstick (Diapheromera femorata) is a species of phasmid or stick insect found across North America. The average length of this species is 75mm (3 in) for males and 95mm (3.7 in) for females. The insect is found in deciduous forest throughout North America, where it eats many types of plant foliage. Even though the common walkingstick is a generalist it does tend to prefer foliage from oak and hazelnut trees. Outbreaks of these insects sometimes occur in local areas; however, the insects have no wings, and dispersal from tree to tree is limited.
