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 ]
Up to 15 pairs of long legs are attached to the rigid body. Together with the antennae they give the centipede an appearance of being 75 to 100 mm (3 to 4 in) in length. [ 6 ] The delicate legs enable it to reach surprising speeds of up to 0.4 meters per second (1.3 ft/s) running across floors, up walls and along ceilings. [ 7 ]
When the cockroach has recovered from the first sting, it makes no attempt to flee. The wasp clips the antenna with its mandibles and drinks some of the haemolymph before walking backwards and dragging the roach by its clipped antenna to steer it to a burrow, where an egg will be laid on it. The wasp larva feeds on the subdued, living cockroach.
Adults are large-bodied and black, with very long antennae; in males, they can be up to twice the body length, but in females they are only slightly longer than body length. Both sexes have a white spot on the base of the wings, and may have white spots covering the wings. Both males and females also have a spine on the side of the prothorax. [2]
In most insect legs, including the posterior four legs of a mantis, the coxa and trochanter combine as an inconspicuous base of the leg; in the raptorial legs, however, the coxa and trochanter combine to form a segment about as long as the femur, which is a spiky part of the grasping apparatus (see illustration). Located at the base of the ...
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.
The long thin body is very hard to make out from real sticks which provides these insects with a way to hide in plain sight. As well as looking like a small branch in a tree, stick insects also behave like a part of the tree, performing swaying motions to give the appearance of moving in the breeze as the rest of the plant may.
The Peltoperlidae, also known as roach-like stoneflies or roachflies, are a family of stoneflies. The family Peltoperlidae comprises 11 genera and 46 known species. [2] Species are semivoltine, meaning their lifecycles last one to two years. Adults of the family usually emerge in late spring or early summer, April through June.
