Monochamus is a genus of longhorn beetles found throughout the world. They are commonly known as sawyer beetles or sawyers, as their larvae bore into dead or dying trees, especially conifers such as pines. They are the type genus of the Monochamini, a tribe in the huge long-horned beetle subfamily Lamiinae, but typically included in the Lamiini today.
Tachypleus tridentatus, commonly known as the Chinese horseshoe crab, Japanese horseshoe crab, or tri-spine horseshoe crab, is a species of horseshoe crab found in Southeast and East Asia, with records from China, Indonesia, Japan, South Korea, Malaysia, the Philippines, Taiwan, and Vietnam.

It has been recorded in Eastern and Northern Europe and Northern Asia. It is a vector of the nematode Bursaphelenchus mucronatus. Larvae burrow into the wood of various conifer species and can be a tree pest, as feeding damage reduces the value of the timber.
Spotted pine sawyer is a common name for several insects and may refer to:
