Large antennae on a longhorn beetle. Antennae (sg.: antenna) (sometimes referred to as "feelers") are paired appendages used for sensing in arthropods. Antennae are connected to the first one or two segments of the arthropod head. They vary widely in form but are always made of one or more jointed segments.
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.
Batocera laena is a species of flat-faced longhorn beetle in ... beetle reaching about 45–60 millimetres (1.8–2.4 in) of length. The length of the antenna may ...
The proportion of longhorn beetle species that act as pollinators is unknown. The fact that two species of longhorn species from distinct subfamilies ( Lepturinae and Cerambycinae ) found on different continents both with significant roles as pollinators could suggest that some capacity for pollination may be common among longhorn beetles.
The body is elongated and oval, typical for longhorn beetles. The head angles forward, showing most of the mouth parts. The thread-like antennae are half to three-quarters of the body length, longer in males. The prothorax is smoothly curved with no spines, narrower than the elytra. The elytra have four ridges and slightly tapering sides. [4]
The adult cottonwood borer is a large longhorn beetle with a black-and-white coloration and black antennae as long or longer than the body. [5] The white portions are due to microscopic masses of hair. [6] The larvae have legless, cylindrical, creamy-white bodies with a brown-to-black head and grow up to 38 millimetres (1.5 in) long.

Batocera wallacei is a huge long-horn beetle reaching about 80–85 millimetres (3.1–3.3 in) of length in the males, while the females are smaller. The length of the antenna may reach about 215–230 millimetres (8.5–9.1 in) in the males. The basic colour of the body is greenish-brownish or grey with whitish dorsal patches on the elytra.
