Pocadius basalis
Pocadius basalis is a species of sap beetle in the family Nitidulidae, first described by Schaeffer in 1911. The species is documented from the southwestern United States, with recent records extending its known range. As a member of Nitidulidae, it belongs to a family commonly associated with fermenting or decaying plant materials, though species-specific biology remains poorly documented.
Psilopyga fasciata
Psilopyga fasciata is a small sap-feeding beetle in the family Nitidulidae, first described from Mexico by Sharp in 1891. The species has undergone taxonomic revision and is currently treated as a synonym of Oxycnemus fasciatus. Records indicate presence in Middle and North America, though specific biological details remain poorly documented in available literature.
Stelidota coenosa
Stelidota coenosa is a small beetle in the family Nitidulidae, commonly known as sap beetles. It feeds on fermenting plant sap, overripe fruit, and other decaying organic matter. The species occurs across North America and is frequently encountered in agricultural settings, particularly where fruit crops are present. It is one of several Stelidota species that can be challenging to distinguish without close examination.
Stelidota geminata
strawberry sap beetle
Stelidota geminata, commonly known as the strawberry sap beetle, is a species of sap-feeding beetle in the family Nitidulidae. This small beetle has a broad host range and is widely distributed across Central America, North America, Oceania, South America, Europe, and temperate Asia. Research indicates it functions as a chemical 'generalist' in host-finding behavior, responding to a wide variety of host volatiles rather than specializing on specific chemical cues. It is known to be associated with fermenting fruit, particularly strawberries (Fragaria spp.), and exhibits both phototactic flights and host-orienting flights when locating food sources. The species has been introduced to various regions outside its native range and is considered a pest of strawberry crops.
Thalycra concolor
Thalycra concolor is a species of sap-feeding beetle in the family Nitidulidae. The species was described by LeConte in 1850 and is known from western and central North America. Like other members of the genus Thalycra, it is attracted to lights at night and associated with fermenting plant materials.
Urophorus
Urophorus is a genus of sap-feeding beetles in the family Nitidulidae, containing at least two described species. The genus is characterized by association with fermenting plant material and fruit. Urophorus humeralis, commonly known as the pineapple beetle, has been documented as a pest of pear fruits in Chinese orchards. The genus is distinguished from related nitidulids by morphological features, though specific diagnostic traits require detailed examination.
