Tree-killing bug invades Southern California, with no answer in sight
Akif Eskalen steps through the dense, damp leaves in a wooded neighborhood, scrutinizing the branches around him. He's looking for evidence of an attack: tiny wounds piercing the bark and sap dried around them like bloodstains.
The victims are box elders, sycamores and coast live oaks, all in some state of suffering. Eskalen approaches a tree riddled with 1-millimeter holes, as if someone used it for miniature target practice. It's time to nab a perp. He selects a hole, pulls out a large knife and expertly levers out a chunk of wood.
