Hamon, A.B. 1979 Angreaceum scale, Conchaspis angraeci Cockerell (Homoptera: Coccoidea: Conchaspididae).. Entomology Circular, Florida Department of Agriculture and Consumer Services Division of Plant Industry 201: 1-2.

Notes: Notes are given on the morphology, distribution in the world and within Florida, food-plants and economic importance of Conchaspis angraeci Ckll., which infests the stems and leaves of the orchid Angraecum eburneum and numerous other ornamental plants and is reported to have caused considerable damage on orchids and on species of Hibiscus, Pittosporum and Coccoloba. No chemicals are registered for specific use against this pest, but compounds used against scale insects can be applied against the adult females, though treatment is best applied during the crawler stage before the formation of the wax scale. This is the only species of Conchaspis recorded from North America, and nothing is known of its life-history.
