Notes

An infestation of scales was found on Cycas micronesica plants on Rota in the vicinity of the Swimming Hole by Nirmala Dongol and Dr. Irene Terry on 12 March 2007. Slide mounts of specimens (AM20070327.002.1 through 7) were made by Dr. Aubrey Moore and sent to scale specialist, Dr. Gillian Watson, who confirmed that these are Aulacaspis yasumatsui.
