The ambrosia beetles (such as Xyleborus) feed on fungal "gardens" cultivated on woody tissue within the tree. Ambrosia beetles carry the fungal spores in either their gut or special structures, called mycangia, and infect the trees as they attack them. Once a beetle chooses a tree, they release spores of this fungus along tunnels within the tree.
The three most species-rich families of woodboring beetles are longhorn beetles, bark beetles and weevils, and metallic flat-headed borers. Woodboring is thought to be the ancestral ecology of beetles, and bores made by beetles in fossil wood extend back to the earliest fossil record of beetles in the Early Permian ( Asselian ), around 295-300 ...
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]

Xanthogaleruca luteola, commonly known as the elm-leaf beetle, is a beetle species in the family Chrysomelidae that is native to Europe but invasive in other parts of the world. [ 2 ] [ 3 ] Description
The size of the holes varies, but they are typically 1 to 1.5 millimetres (5 ⁄ 128 to 1 ⁄ 16 in) in diameter for the most common household species, although they can be much larger in the case of the house longhorn beetle. Adult beetles that emerge from wood may also be found in the summer months.
As larvae they eat wood of dead and dying pines, [3] their host plants are mainly ponderosa pine and Douglas fir. [2] They lay eggs in bark crevices of these trees. [3] The larvae bore tunnels through the sapwood and heartwood. [3] They have a life cycle of several years long. [3]
The Curculionidae are a family of weevils, commonly called snout beetles or true weevils. They are one of the largest animal families with 6,800 genera and 83,000 [ 1 ] species described worldwide. They are the sister group to the family Brentidae .
