Could you please help me to identify this bug I have never seen one of these before. It was on our ceiling and was terrifying my young son (unfortunately the bug didn’t survive). It was about one inch long excluding legs and feelers. I would like to be able to tell my son what it is and whether or not it is harmless. We live in San Diego, California.
The Eucalyptus Tree Borer, Phoracantha semipunctata, is harmless to you, but will do considerable damage to your eucalyptus trees. This insect was introduced to southern California from Australia where it has multiplied due to the absence of natural predators. Young bore into the wood of Eucalyptus trees and have destroyed many stands of this common tree.
