Acer rubrum [sic--likely a mistake?]

Pouch-like leaf swellings, diameter 1/12 inch, scale insect, summer

Plant Galls and Gall Makers

Diaspidiotus liquidambaris (Kotinsky, 1903)

Cryptophyllaspis liquidambaris
Chemnaspidiotus liquidambaris 
Diaspidiotus liquidambaris
Cryptophyllaspis (Diaspidiotus) liquidambaris

Hosts: Liquidambar styraciflua, Acer rubrum

Biology: Causing the formation of pit galls on the leaves, each gall being occupied by a single female the scale of which fills the opening of the gall (Ferris, 1938a).

Structure: Scale flat, white, exuviae central. Scale of the male exposed upon the leaves, white, elongate oval, exuvia toward one end (Ferris, 1938a). Colour photograph by Gill (1997).

ScaleNet: A literature-based model of scale insect biology and systematics

Small bead galls between the veins on the upper (occasionally lower) side of Liquidambar styraciflua leaves. They strongly resemble the galls induced by Vasates quadripedes on Acer rubrum, and are likely to be confused with that species by those unable to distinguish the hosts. The host record on Acer rubrum reported in Felt and repeated on ScaleNet seems likely to be a mistake.
