Phyllophaga rossi
Saylor, 1939
Phyllophaga rossi is a of scarab beetle in the Scarabaeidae, described by Saylor in 1939. It belongs to the Phyllophaga, commonly known as May or June beetles, a large group of soil-dwelling scarabs whose larvae feed on plant roots. The species is recorded from Arizona, USA, within the Nearctic region. Like other members of its genus, it is presumed to have a subterranean larval stage and aerial stage, though specific biological details for this species remain poorly documented.

Identification
Phyllophaga rossi can be distinguished from other Phyllophaga based on morphological features described in the original 1939 description by Saylor. As with many , identification relies on examination of male genitalia and external body characters including size, coloration, and punctation patterns. The species is part of a taxonomically challenging where species-level identification typically requires examination and comparison with .
Habitat
Recorded from Arizona, USA. The likely inhabits areas suitable for root-feeding scarab larvae, including soils in association with vegetation that supports larval development. Specific microhabitat preferences are not documented.
Distribution
Nearctic region: USA (Arizona). Distribution records indicate presence in North America with confirmed occurrence in Arizona.
Life Cycle
Presumed to follow the typical Phyllophaga pattern of a three-year with subterranean larval stages feeding on roots, in soil chambers, and of . This inference is based on -level characteristics and has not been confirmed for P. rossi specifically.
Ecological Role
As a member of a root-feeding scarab , the likely contributes to soil nutrient cycling through burrowing activity and serves as prey for soil-dwelling and . Larval root-feeding may influence plant composition, though specific impacts are unrecorded.
