Conotelus mexicanusObserver
aubreymooreDescription
Photo of this beetle caught on a sticky trap was sent to me by Dr. James McConnell. Several of these beetles were flying around the endangered tree, Serianthes nelsonii growing in the Guam Plant Extinction Prevention Program nursery at the University of Guam.
This appears to be a new island record for Conotelus mexicanus, which has been reported from Hawaii and the Commonwealth of the Northern Mariana Islands.

Encarsia noyesiObserver
aubreymooreDescription
Reared from lemon leaves infested with two whitefly species: Aleurocanthus sp. and Aleurothrixus floccosus (https://www.inaturalist.org/observations/160823226).
This parasitoid probably emerged from Aleurothrixus floccosus. See (https://www.inaturalist.org/observations/166507793).
Image scale: 240.5 pixels/mm.
Possibly a new island record for Guam.

Genus AleurocanthusObserver
aubreymooreDescription
My son, Jonoe Moore, gave me some leaves from his lemon tree this morning. Infested with orange spiny whitefly or citrus blackfly. Indicated by black spiny immatures on lower leaf surfaces.
There is also a second whitefly species here, probably Aleurothrixus floccosus. Made a separate observation for this (https://www.inaturalist.org/observations/166507793).
No signs of parasitism, but I will try to rear some out.
Two parasitoids were reared. One looks like Eretmocerus sp. ((https://www.inaturalist.org/observations/166497059). The other looks like Encarsia noyesi ((https://www.inaturalist.org/observations/166497059) and probably emerged from what I am calling Aleurothrixus floccosus ((https://www.inaturalist.org/observations/166507793).
