Taxonomic affinities.

The morphologically closest species is the Nearctic Empria multicolor , from which Empria candidata can be distinguished by the following characters: femora predominantly and most other parts of legs at least partly black (legs are almost entirely yellowish in Empria multicolor ), tarsal claws simple or with a minute inner tooth (with a long subbasal tooth in Empria multicolor ), shallowly emarginated clypeus (deeply emarginated in Empria multicolor ), and postocellar area more than 1.6 times wider than long (less than 1.5 in Empria multicolor ) (see also Smith 1979).

Host plants.

Betula ( Lorenz and Kraus 1957; Verzhutskii 1981), Betula pendula Roth (under the name Betula verrucosa in Verzhutskii 1966).
