Eucalyptus tree infested with lerp psyllid. I'm not sure what species this tree is, so I included pictures of the leaves and trunks as well as infected leaves. Notice that this tree has been tagged with two spray-painted blue dots for some reason. At least 3 eucalyptus trees in this park are infested.

Red Gum Lerp Psyllid infestation of eucalyptus tree. Ophelimus maskelli was co-existant on this tree. This tree is representative of at least a dozen or more eucalyptus trees in this park. I saw signs of lerp psyllid on all of them. Some of these trees were marked with spray-painted blue dots on the trunk - don't know what this means.

Infested Blue Gum Eucalytptus (Almaden Lake Park) This tree was infested with both lerp psyllids and Australian Tortoise Beetles. You can see at least two psyllids and some lerps in the first photo. The second photo is the tree itself. NOTE: This tree is representative of over 50 eucalyptus trees in this park. I closely inspected 6 of them and found evidence on all of them of chewing damage and lerp psyllid infestation.
