MorphologyRead full entry
Common walkingsticks have very elongated bodies that are almost cylindrical. The abdomen and thorax are long and the abdomen bears a pair of single segmented cerci that resemble palps and serve as a clasper. The head is small but bears antennae that are about 2/3 the length of the body. Legs are slender and the tarsi are five segmented.
Adult males average 75 mm in length, while females are slightly larger at about 95 mm. Nymphs of the first five instars reach average lengths of about 11, 18, 25, 34, and 46 mm, respectively.
A distinguishing feature is the supra-anal plate, which is a small and membranous lobe above the anus. Their maxillae each contain a lacina with a tridentate structure. The species is apterous. Members of Diapheromera femorata exhibit square-shaped heads. Males are brown, whereas females have a hint of green to their brown color. There are other distinguishing characteristics that separate the two sexes; the femurs of males tend to be banded, their seventh abdominal segment is longer than their ninth, and they feature cerci that lack spines.
Average length: Males 75mm, Females 95mm mm.
Other Physical Features: ectothermic ; heterothermic ; bilateral symmetry
