Diomus xanthaspis
Diomus xanthaspis is a small lady beetle species in the family Coccinellidae, first described by Mulsant in 1850. It is native to North America, with records from Brazil (Bahia) as well. The genus Diomus comprises minute lady beetles, many of which are poorly documented in terms of their biology and ecology. This species remains among the lesser-known members of the family, with very few observations recorded.
Microweisea misella
Micro Lady Beetle
Microweisea misella is a minute lady beetle (Coccinellidae) native to North America. Adults measure only 1–1.5 mm in length and are darkly colored. The species is a specialized predator of armored scale insects (Diaspididae), particularly on blueberry and other shrubs and trees. It has been documented across southern Canada and much of the United States, and is associated with urban and agricultural habitats where scale infestations occur.
Nephus atramentarius
dusky lady beetle
Nephus atramentarius is a small lady beetle species in the family Coccinellidae. It was originally described as Scymnobius atramentarius by Boheman in 1859. The species is found in North America. It belongs to the genus Nephus, which contains minute lady beetles often associated with scale insects.
Psyllobora parvinotata
Small-spotted Fairy Lady Beetle, small-spotted psyllobora
Psyllobora parvinotata is a minute lady beetle in the tribe Psylloborini, distinguished by its reduced spot pattern compared to congeners. Adults measure 2.75–3.40 mm and exhibit pale, often faint markings on the elytra. The species occurs in the southeastern United States, with records from Florida to Louisiana. It belongs to a genus whose members are specialized feeders on powdery mildews and other plant-pathogenic fungi.
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 louisianae
Scymnus louisianae is a small lady beetle (Coccinellidae) described by J. Chapin in 1973. It belongs to the subfamily Scymninae, a group of minute lady beetles often associated with scale insect and mealybug prey. The species is documented in North America with a notable concentration of observations. Like other Scymnus species, it likely serves as a biological control agent for agricultural and forest pests.
Scymnus pacificus
Scymnus pacificus is a small lady beetle (Coccinellidae) described by Crotch in 1874. Adults measure approximately 2.0–2.8 mm in length. The species occurs in western North America, with records from California extending eastward to western Texas, Colorado, and Utah. As a member of the genus Scymnus, it belongs to a group of minute lady beetles often associated with scale insect and mealybug predation, though specific ecological data for this species remain limited.
Scymnus securus
Coastal Marsh Scymnus
Scymnus securus is a small lady beetle (Coccinellidae) described by Chapin in 1973. It belongs to the subfamily Scymninae, a group of minute lady beetles often associated with wetland habitats. The species is known from coastal marsh environments in eastern North America, with confirmed records from Ontario, Canada. It is among the less frequently documented Scymnus species, with limited observational data available.
Zilus horni
Eastern Velvethead Ladybug
Zilus horni is a minute lady beetle in the family Coccinellidae, measuring approximately 1.40–1.60 mm in length. The species is native to eastern North America, with records from Maryland to Florida and west to Wisconsin and Louisiana. It was described by Gordon in 1985 and named in honor of American entomologist George H. Horn. The specific epithet commemorates Horn's contributions to coleopterology.
