Scaralina metcalfi

Scaralina metcalfi is a species of planthopper in the family Fulgoridae. It is found from Arizona in the United States south to the Sierra Madre Occidental in Mexico. It is one of four species that were, for several decades, erroneously grouped together under a single name, Alphina glauca; this name is now treated as a synonym of S. marmorata.

Biology

Scaralina metcalfi typically occurs at higher elevations, above 1000 meters, and is associated with oaks. Of the three co-occurring species in the area where it is found, it is much rarer than the other two species, and may feed on a rarer host oak species.

Distribution

Scaralina metcalfi is found in a subset of the Madrean Sky Islands in Arizona down into Chihuahua. In Arizona, its range is overlapped by the ranges of Scaralina aethrinsula and Scaralina cristata, and all three species can be found together.
