Male, Beauchêne disarticulation, MHNT Macrodontia cervicornis (Linnaeus, 1758), also known as the sabertooth longhorn beetle, is one of the largest beetles, if one allows for the enormous mandibles of the males, from which it derives both of the names in its binomen: Macrodontia means "long tooth", and cervicornis means "deer antler".
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 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.
Adult beetles are 8–30 mm long reddish-brown to black, while males are generally smaller and lighter in colour. [3] [4] 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.
Tetropium fuscum, the brown spruce longhorn beetle, is a species of beetle in the family Cerambycidae. [1] It was described by Johan Christian Fabricius in 1787. [1] Tetropium fuscum is native to Europe and Northern Asia, and has been introduced to Nova Scotia, Canada. [2] Brown spruce longhorn is a pest of spruce trees.
