Eucalyptus psyllid - Glycaspis brimblecombei

Eucalyptus psyllid - Glycaspis brimblecombei
Brisbane, San Mateo County, California, USA
April 30, 2016
Leaves of eucalyptus tree are covered with these white cases, which appear to be sugar. When I opened one of these cases, I found the pupa. Lerps are from Glycaspis brimblecombei. One of the lerps contained a pupa of a parasitoid wasp.

Adult Psyllaephagus bliteus
Added a photo of the adult wasp, which emerged from one of these lerps. It's ID was tentatively confirmed as Psyllaephagus bliteus on INaturalist http://www.inaturalist.org/observations/3153162.

lerps from G. brimblecombei; pupa = Psyllaephagus bliteus?
The parasitoid was introduced into CA in 2000 to combat the psyllid. This article from the Australian Journal of Entomology (2006) has dorsal and ventral images of the pupa, which seem to be a perfect match for yours. There are no other known parasitoids of this psyllid.

 
Parasitoid pupa
Ah, that's why the pupa didn't look like the photos of the psyllid. Thanks for the ID and info.
