Serica anthracina
Serica anthracina is a small scarab beetle in the family Scarabaeidae, described by LeConte in 1856.

It belongs to the genus Serica, a large and taxonomically challenging group of chafers commonly known as May beetles or June beetles. Adults are distinguished from close relatives by subtle morphological differences, particularly in antennal structure. The species has a restricted distribution in the southeastern United States.
Serica atracapilla
Serica atracapilla is a small scarab beetle in the family Scarabaeidae, distributed across eastern and central North America. Adults measure approximately 10 mm in length and are characterized by their chestnut-brown coloration and polished, shining upper surface lacking any silky or pruinose luster. The species has been recorded from 19 U.S. states and 7 Canadian provinces, indicating a broad geographic range within the Nearctic region.
Serica campestris
Serica campestris is a small scarab beetle species in the family Scarabaeidae, first described by Dawson in 1919. Adults measure approximately 8.5 mm in length and are characterized by their very dark mahogany coloration with a bare, polished, and shining upper surface that lacks any sericeous or pruinose luster. The species is known from a limited distribution in the central United States.
Serica vespertina
Serica vespertina is a small scarab beetle in the family Scarabaeidae, measuring approximately 8.5 mm in length. It is characterized by its uniformly light brown, polished, and shining appearance. The species is distributed across North America, with two recognized subspecies showing distinct geographic ranges in the eastern and central United States.
Serica vespertina accola
Serica vespertina accola is a subspecies of scarab beetle in the family Scarabaeidae, described by Dawson in 1921. It belongs to a genus of small, brownish beetles commonly known as May beetles or June beetles. The subspecies is documented from North America, though specific details about its biology and ecology remain limited in available sources.
