The Pine Beetle is a small insect known for infesting and damaging pine trees. These beetles bore into the bark, disrupting the tree's ability to transport water and nutrients. This can lead to tree death, especially in large infestations. There are several species of Pine Beetles, with the most notable being the Mountain Pine Beetle. This species has caused significant damage to forests in North America, particularly in the western United States and Canada. Their population can increase rapidly, especially during warm weather, leading to widespread tree mortality.
