In response to the unprecedented spread of bark beetles in the Rocky Mountains and other parts of the western United States, the U.S. Forest Service formed the Western Bark Beetle Research Group (WBBRG) in 2007—a collaboration between scientists from three research stations that pools knowledge and resources to better understand the threat and eventually develop a strategy to combat it.

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.
Dutch elm disease was spread by elm bark beetles, yet the tree mortality was caused by a pathogen. [4] Chestnut blight is a fungus spread through wind dispersal and rain splatter; the blight traveled up to 50 miles in a year by natural means. [5] Insect pests, once they reach the adult phase, have the ability to disperse by flight.
The metallic green and brown insects are known to feed on more than 300 species of plants, including roses, ornamental trees and vegetables.

Trogossitidae, also known as bark-gnawing beetles, are a small family in the superfamily Cleroidea. Many taxa formerly within this family have been removed (as of 2019) to other families, such as Lophocateridae , Peltidae , Protopeltidae , Rentoniidae , and Thymalidae . [ 1 ]
Juniperus scopulorum is a small evergreen tree that in favorable conditions may reach as much as 20 metres (66 feet) in height. [4] However, on sites with little water or intense sun it will only attain shrub height, and even those that reach tree size will more typically be 4.6–6.1 metres (15–20 feet) tall in open juniper woodlands.
