Adults measure 3.5–4 mm in length and display distinctive coloration with black or brown elytra marked by yellow to orange patterns. The species has been documented across a restricted range in western North America, from Washington through Nevada to northern California. Like other members of Coccinellidae, it is presumed to be predatory, though specific ecological details remain poorly documented.
Nipus
Nipus is a genus of lady beetles in the family Coccinellidae, established by Casey in 1899. The genus comprises at least four described species distributed in North America: N. biplagiatus and N. niger (both described by Casey, 1899), and N. occiduus and N. planatus (both described by Gordon, 1970). These beetles are part of the diverse Coccinellidae family, which includes many species valued for predation on pest insects.
Scymnus compar
dusky lady beetle
Scymnus compar is a small lady beetle (Coccinellidae) described by Thomas L. Casey in 1899. It belongs to the subfamily Scymninae, a group commonly known as dusky lady beetles due to their typically subdued coloration compared to the brightly spotted species familiar to most observers. The species is documented from North America, with specific records from Ontario, Canada. Like other members of its genus, it is presumed to be a predator of small soft-bodied insects, though direct observations of its biology remain limited.
Scymnus garlandicus
garland lady beetle
Scymnus garlandicus, commonly known as the garland lady beetle, is a small dusky lady beetle in the family Coccinellidae. It belongs to the subfamily Scymninae, a group of minute lady beetles often characterized by their diminutive size and inconspicuous coloration. The species was described by Casey in 1899 and is recorded from North America. Like other members of Scymnus, it is presumed to be a predator of small soft-bodied insects, though specific biological details remain poorly documented.
Scymnus kansanus
Kansas Lady Beetle
Scymnus kansanus, commonly known as the Kansas lady beetle, is a small dusky lady beetle in the family Coccinellidae. It was described by Thomas Casey in 1899. The species is recorded from North America, with specific distribution records from Canada (Ontario and Québec) and the United States. It belongs to the genus Scymnus, a diverse group of small lady beetles often characterized by their subdued coloration and association with scale insects and other small prey.
