Stenolophus
Seedcorn Beetles
Stenolophus is a large genus of ground beetles in the family Carabidae, comprising over 190 described species distributed across the Palearctic, Nearctic, Near East, and North Africa. Commonly known as seedcorn beetles, several species are significant agricultural pests of corn and other crops. The genus includes both univoltine and potentially multivoltine species depending on geographic location.
Stenolophus binotatus
Stenolophus binotatus is a ground beetle species in the family Carabidae. It occurs in North America, with records from the United States. The species has been documented in blacklighting surveys in Kansas during early spring. It belongs to the genus Stenolophus, commonly known as seedcorn beetles.
Stenolophus comma
Common Stenolophus Beetle, seedcorn beetle
Stenolophus comma is a small ground beetle commonly known as the Common Stenolophus Beetle or seedcorn beetle. Native to North America, it is primarily associated with agricultural habitats where adults feed on germinating seeds and seedlings of row crops. The species has been extensively studied in Iowa, where it completes two generations annually and overwinters as adults in soil and crop residues.
Stenolophus humidus
Humid Harp Ground Beetle
Stenolophus humidus is a ground beetle species in the family Carabidae, first described by Hamilton in 1893. It belongs to the genus Stenolophus, a group commonly known as seedcorn beetles. The species is documented from North America, with records from both Canada and the United States. Like other members of its genus, it is likely associated with open, moist habitats.
Stenolophus infuscatus
Stenolophus infuscatus is a species of ground beetle in the family Carabidae. It occurs in North America. As a member of the genus Stenolophus, it belongs to a group of small to medium-sized carabid beetles commonly known as seedcorn beetles, which are frequently encountered in agricultural and disturbed habitats.
Stenolophus lecontei
LeConte's Seedcorn Beetle
Stenolophus lecontei is a ground beetle in the family Carabidae, commonly known as LeConte's Seedcorn Beetle. It is distributed across North America, with records from both the United States and Canada. The species is closely related to Stenolophus comma, with which it shares the common name "seedcorn beetle" and similar ecological associations. Adults have been observed at blacklight in early spring, suggesting nocturnal activity patterns.
