The exact number is not known as not all of them have been discovered yet! Oak beetles are attracted to trees that are severely compromised. Several species, such as the mountain pine beetle (Dendroctonus ponderosae), attack and kill live trees. Many adult beetles eat plant-based foods or other insects, and some can cause considerable damage to decorative plants and gardens. A similarly aggressive species in Europe is the spruce ips Ips typographus. The beetle typically lives in tropical forests and jungles. The larvae tunnel under the bark as they eat and grow, producing winding tunnels between the bark and the sapwood of the tree.
