Cordulegastridae nymphs will almost entirely conceal themselves in sand or silt, exposing only their eyes to see, antennae for sensing prey, and the tip of their abdomen to breathe dissolved oxygen. [11] Nymphs will consume any prey they can capture, going as far as eating smaller larvae of the same species. [12]
Megalopyge opercularis is a moth of the family Megalopygidae.It has numerous common names, including southern flannel moth for its adult form, and puss caterpillar, asp, Italian asp, fire caterpillar, woolly slug, opossum bug, [3] puss moth, tree asp, or asp caterpillar.
The females emit pheromones, which the male can detect through his large, plumose (feathery) antennae. Males can fly for miles to reach a female. Males can fly for miles to reach a female. After the moths mate, the female spends the majority of the remainder of her life laying eggs, while the male may mate several more times.
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 ]
The antennae are flabellate, and are covered in specialised chemoreceptors, likely to detect females over long distances. [ 7 ] Adult male Strepsiptera have eyes unlike those of any other insect , resembling the eyes found in the trilobite group Phacopina .
Antennae can also locate other group members if the insect lives in a group, like the ant. The common ancestor of all arthropods likely had one pair of uniramous (unbranched) antenna-like structures, followed by one or more pairs of biramous (having two major branches) leg-like structures, as seen in some modern crustaceans and fossil ...
The longhorn beetles (Cerambycidae), also known as long-horned or longicorns (whose larvae are often referred to as roundheaded borers), are a large family of beetles, with over 35,000 species described. [2] Most species are characterized by antennae as long as or longer than the beetle's body.
The female body is 15–36 mm (5 ⁄ 8 – 1 + 3 ⁄ 8 in), and the male is 9–32 mm (3 ⁄ 8 – 1 + 1 ⁄ 4 in) long. Both sexes have long, black, bristle-shaped antennae, which are rather close together. [6] [7] The body of the male is black, except for the orange middle part of the abdomen. The wings are yellowish-translucent and the ...
