Identification

Adult female is round or oval and has a reddish color with a black pattern. Field characteristics are enough to distinguish this species. It is distinct morphologically from all other N. American soft scales except E. tiliae, which lacks the distinct dorsal pattern of E. kunoense. E. kunoense has a broad internal "lip" of the body margin where the adult female attaches to the host.

Range

Introduced from the orient. Has been in California since at least 1896. As of 1988, was known only in Bay Area counties (Alameda, Santa Clara, Contra Costa) and Lake, Butte, and Sacramento counties. (1)

Season

One generation per year (March - May). (1)

Food

Stone fruit trees; apple trees; pear trees. (1)
