Palm aphid - Cerataphis

Palm aphid - Cerataphis
Ann Arbor - Botanical Garden Conservatory, Washtenaw County, Michigan, USA
June 21, 2006
Size: ca. 2mm
This is presumably a whitefly larva ("pupa"), observed on a palm frond in a tropical plant conservatory. The plant was heavily covered in honeydew. The black color would be expected for a greenhouse whitefly that had been parasitized by Encarsia. This however does not appear to be GH whitefly, and I saw no evidence of parasitoid emergence. We otherwise have spiraling whitefly in this greenhouse, which looks totally different.

palm aphid
This is actually an aphid in the genus Cerataphis. They are often confused for whitefly pupae. Since it was found on palm, it is likely the palm aphid, C. brasiliensis. This species is common in Florida. More info at although this pub. uses an older name.

Mulberry whitefly ?????
There is a picture very similar to this one in Cranshaw (1). The insect name is Mulberry whitefly (Tetraleurodes mori).
However, I don’t know if there are many species of nymphs which look similar. For example, p 288, Cranshaw writes that Citrus blackfly nymphs are also black with a white wax fringe.

That's one strange looking pupa! What's with the white stuff around it?
