Malumphy, C.P., Sanchez, M.D., & Hamilton, M.A. 2015 First report of lesser snow scale Pinnaspis strachani (Cooley) (Hemiptera: Diaspididae) killing Varronia rupicola (Urb.) Britton in the British Virgin Islands. Entomologist's Monthly Magazine 151: 285-288
Notes: Varronia rupicola (Urb.) Britton (Syn. Cordia rupicola Urban) (Boraginaceae) is a woody shrub native to the islands of Puerto Rico, Vieques, and Anegada in the Caribbean that is threatened with extinction. On 26 July 2013, there was found a V. rupicola plant at Setting Point on Anegada exhibiting severe dieback due to a massive infestation of scale insects. A sample consisting of a branch smothered in hundreds of male and female scales was submitted to Fera where the pest was identified as Pinnaspis strachani (Cooley) (Hemiptera: Diaspididae).
