A pair of mating D. femorata in the Hudson Highlands region of New York. The common walkingstick is a slender, elongated insect that camouflages itself by resembling a twig. . The sexes differ, with the male usually being brown and about 75 mm (3 in) in length while the female is greenish-brown, and rather larger at 95 mm (3.7 i
The Phasmatodea (also known as Phasmida or Phasmatoptera) are an order of insects whose members are variously known as stick insects, stick bugs, walkingsticks, stick animals, or bug sticks. They are also occasionally referred to as Devil's darning needles , although this name is shared by both dragonflies and crane flies. [ 1 ]
Medauroidea extradentata, commonly known as the Vietnamese or Annam walking stick, is a species of the family Phasmatidae. They originate in Vietnam and are found in tropical forests there. They eat a variety of foliage, though in captivity they commonly eat blackberry bramble, hawthorn, oak, red maple, and roses.
Dryococelus australis, also known as the Lord Howe Island stick insect, Lord Howe Island phasmid or, locally, as the tree lobster, [2] is a species of stick insect that lives in the Lord Howe Island Group. It is the only member of the monotypic genus Dryococelus. Thought to be extinct by 1920, it was rediscovered in 2001. [3]
It is the largest insect in North America, growing up to 7 inches in length. [6] [7] [8] Giant walkingsticks exhibit sexual dimorphism, with females generally being significantly larger than males. [9] Giant walkingsticks have spines on their middle and hind legs; males have only a single, larger spine on each hind leg.
The Phasmatidae are a family of the stick insects (order Phasmatodea). They belong to the superfamily Anareolatae of suborder Verophasmatodea. [1] Like many of their relatives, the Phasmatidae are capable of regenerating limbs and commonly reproduce by parthenogenesis. Despite their bizarre, even threatening appearance, they are harmless to humans.
Timema cristinae, or Cristina's timema, is a species of walking stick in the family Timematidae. This species is named in recognition of the person who first found and collected it, Cristina Sandoval. [1] It is found in North America, in a small region of southern California, US. [2] T. cristinae is one of the smallest species of stick insects. [1]
Compared to other stick insects (order Phasmatodea), the genus Timema is considered basal; that is, the earliest "branch" to diverge from the phylogenetic tree that includes all Phasmatodea. To emphasize this outgroup status, all stick insects not included in Timema are sometimes described as "Euphasmatodea."
