Eastern eyed click beetle

The Eastern eyed click beetle (Alaus oculatus) is a member of the Elateridae family, recognizable by the two large, black, eye-like spots on its pronotum. These spots serve as a defensive mechanism, mimicking a larger creature to deter predators.

This beetle is primarily found in wooded areas and orchards, specifically targeting hardwood trees. Adult beetles are often spotted on the bark of standing dead or decaying trees, which provides the ideal habitat for their reproductive cycle.

The life cycle begins when eggs are deposited into cracks in the bark or damp soil. The larvae, often called wireworms, live inside decaying wood. They are known for being opportunistic feeders, consuming rotting wood matter as well as other small soil-dwelling insects.

In terms of damage, Alaus oculatus is not considered a primary pest for healthy trees. However, they can exacerbate structural damage in decaying wood. When present in large numbers, their tunneling activities accelerate the breakdown of wood, potentially compromising the stability of an already weakened tree.

Management strategies focus on orchard sanitation rather than chemical intervention.

• Removing deadwood and decaying stumps from the garden area.
• Pruning damaged branches to prevent wood decay.
• Improving overall tree health to make trees less attractive to wood-boring insects.
