White Lerp Insect

Glycaspis sp.

Description:

Who can place so many eggs sacs on eucalyptus tree? I knew that eucalyptus trees were toxic to most insects but these trees are now affected for several seasons of drought. Ants and different kind of wasp were around the sacs (looking for food). Until I saw the pictures in the PC screen I noticed there were very small arthropods maybe the hatchings. There are dozens of leaves from different eucalyptus trees affected.

Habitat:

Semi desert

Thank you John La Salle for the new info.

Yes, they introduced an Australian parasitic wasp - Psyllaephagus bliteus.
Here is a reference

This work was done in California - not sure how widely the wasp has been spread since then.

Thank you very much for the info Jhon Lasalle. I remember back in 2001 this psyllid species hit most of the eucalyptus trees in Mexico. At the time they said they were going to breed a bug that eat them but I don't know if they did but it seems it is back maybe because of several drought seasons.

Definitely a Glycaspis sp. (Psyllidae) Might even be G. brimblecombei - a fairly notorious invasive psyllid species which can even defoliate eucalyptus trees in plantations.
Check out this paper and the references in it.

Apparently first hit Mexico in 2001.
These are Australian in origin.
