Though the vast majority of woodboring beetles are ecologically important and economically benign, some species can become economic pests by attacking relatively healthy trees (e.g. Asian longhorn beetle, emerald ash borer) or by infesting downed trees in lumber yards. Species such as the Asian longhorn beetle and the emerald ash borer are ...

The cottonwood borer (Plectrodera scalator) is a species of longhorn beetle found in the United States east of the Rocky Mountains that feeds on cottonwood trees. [3] It is one of the largest insects in North America, with lengths reaching 40 millimetres (1.6 in) and widths, 12 mm (0.47 in). It is the only species in the genus Plectrodera. [4]
Bark beetles enter trees by boring holes in the bark of the tree, sometimes using the lenticels, or the pores plants use for gas exchange, to pass through the bark of the tree. [3] As the larvae consume the inner tissues of the tree, they often consume enough of the phloem to girdle the tree, cutting off the spread of water and nutrients.
Megacyllene robiniae, commonly known as the locust borer, is a species of longhorn beetle endemic to eastern North America. It is a serious pest of Robinia pseudoacacia , the black locust tree, with which it is sympatric .
The emerald ash borer (Agrilus planipennis), also known by the acronym EAB, is a green buprestid or jewel beetle native to north-eastern Asia that feeds on ash species (Fraxinus spp.). Females lay eggs in bark crevices on ash trees, and larvae feed underneath the bark of ash trees to emerge as adults in one to two years.
The alder borer's antennae are banded white and black. The male's antennae are longer than the body; the female's are shorter. The male's antennae are longer than the body; the female's are shorter. Long and narrow, the body of R. funebris may grow to be 38 millimetres (1.5 in).
Prionus laticollis, also known as the broad-necked root borer or broad necked prionus, is a root-boring longhorn beetle described by Dru Drury in 1773.
