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.
Asian long-horned beetle larvae do not pupate before they reach a critical weight, so additional larval instars can occur. [ 2 ] Pupation usually occurs in spring at the end of the larval tunnel in the sapwood , eclosion occurs 12–50 days later, and adults will chew out of the tree approximately one week after eclosion.

Rhagium mordax, the black-spotted longhorn beetle, [1] is a species of long-horned beetle. [2] This beetle is found throughout Europe and to Kazakhstan and Russia. [2] Larvae develop in silver fir, hazel, European weeping birch, European beech, and the European chestnut. [2]
Oemona hirta, the lemon tree borer, also known as the whistling beetle or the singing beetle, is a longhorn beetle endemic to New Zealand. [1] Its larvae are generalist feeders, boring into the wood of a wide variety of trees, native and introduced.
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.
The body is elongated and flattened and slightly haired. Elytrae have 2 or 3 parallel ridges. The antennae of females are not longer than half of the body and those of males are about two-thirds of the body length. The egg is white and elongated, and is around 0.5 mm × 1.9 mm in size. The larva is white, flattened and up to 28–39 mm long.
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 [1] 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 ...
The citrus long-horned beetle (A. chinensis; syn. A. malasiaca) has been introduced from Asia to Europe and North America. It is a pest of citrus and other fruit and nut trees. It infests forest trees and ornamentals. It attacks over 100 species of trees, shrubs, and herbs from many plant families. Damage from its wood-boring larvae can kill ...
