What Do Bark Beetles Eat?

Bark beetles are a group of insects that primarily feed on the inner bark of trees.

• Inner Bark of Trees: Bark beetles bore into trees and consume the phloem, cambium, and xylem layers. These layers provide nutrients and water necessary for their survival.
• Fungi: Some bark beetles carry symbiotic blue-stain fungi which they cultivate and consume. This provides additional nutrients to the beetles.
• Dead or Dying Wood: Bark beetles often inhabit and feed on dead, dying, or weakened trees, as the wood is easier to penetrate and consume.

How do Bark Beetles Eat?

Bark beetles feed on the inner bark of trees, specifically the phloem, cambium, and xylem layers.

• Bark beetles bore into trees using their mandibles.
• They create tunnels, called galleries, where they lay eggs.
• The larvae also feed on the tree's inner bark.
• They extract nutrients from the tree's tissues, causing damage or even killing the tree.

What do Bark Beetles Drink?

Bark beetles, like many insects, primarily consume plant matter. They are known for boring into the bark of trees to feed on the phloem (inner bark), xylem, and cambium layers.

• Tree Sap: This is the primary source of nutrients for bark beetles. It's a fluid transported in xylem cells of a tree.
• Water: Bark beetles can also consume water, usually absorbed from the tree tissues they inhabit or from the surrounding environment.
