Food
The host plant is often needed for identification of members of this genus (for the specialists):
Empoa albicans: Betula spp. (birches)
Empoa apicata: Ostrya virginiana (American hophornbeam)
Empoa aureotecta: Quercus spp. (oaks)
Empoa bella: Alnus incana rugosa (speckled alder)
Empoa casta: Quercus spp. (oaks), Ulmus americana (American elm)
Empoa gillettei: polyphagous; trees in 6+ families
Empoa latifasciata: Alnus spp. (alders)
Empoa platana: Platanus spp. (sycamores)
Empoa querci: Quercus spp. (oaks)
Empoa rubricola: Quercus rubra (northern red oak)
Empoa saffrana: Polyphagous. Recorded on Fagus grandifolia (American beech), Ostrya virginiana (American hophornbeam), and Ulmus americana (American elm)
Empoa scripta: Betula occidentalis (water birch) and B. papyrifera (paper birch)
Empoa spinosa: Betula glandulifera (bog birch) and B. glandulosa (American dwarf birch)
Empoa unifasciata: ?
Empoa venusta: Tilia americana (American basswood), Ulmus sp. (elm)
Empoa vestita: Ulmus spp. (elms)
Remarks
"[...] most species cannot be separated based on genitalia, only albicans and spinosa have distinct genitalia. We have limited barcode data, but what we do have suggests little or no differentiation within the gillettei complex at least. However, there is supposedly some association of the different colour forms with specific hosts. I think if the species are all truly distinct they must be very recently diverged." - J. Kits pers. comm. to S. Hendrix
