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]
The members of the Cerambycidae (Longhorn Beetles) family are named for their long antennae, sometimes exceedingly so. The antennae of males are usually longer than those of females, and often the antennae are attached to the head in a strange notch at the front of the eye. Styloxus fulleri is a smaller species, at about 12–13 mm in length.
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 adult beetle can be 11 to 28 mm (0.43 to 1.10 in) long, and it has a W-shaped third stripe on the elytra. The antennae of both sexes are dark brown to black. The male's antennae are two-thirds its body length, and the female's are one-half. The legs are reddish brown.
Phoracantha semipunctata was initially observed in the late 1980s in Setubal Portugal. [2] The beetle is classified as a species within the Phoracantha genus, situated within the Phoracanthini tribe of beetles under the Cerambycinae subfamily, which it shares with 11 other genera including Coptocercus, Allotisis, Thoris, Epithora, Skeletodes, Atesta, Paratesta, Steata, Coleocoptus, Phytrocaria ...
Darkling beetle is the common name for members of the beetle family Tenebrionidae, comprising over 20,000 species in a cosmopolitan distribution. Taxonomy [ edit ]
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 male beetle is smaller than the female and is much the same width for most of its length whereas the female is broadest in the posterior third of its length. [1] The larva is pale coloured, up to fifteen millimetres long, flattened and broadly ovate. The head is dark and much narrower than the prothorax. The antennae and legs are well ...
