Guides

  • Scymninae

    Scymnine lady beetles, Minute lady beetles

    Scymninae is a subfamily of minute lady beetles within Coccinellidae, comprising at least 170 described species globally. Members are recognized as efficient biological control agents, particularly in agricultural systems. The subfamily is taxonomically diverse, represented by 5 tribes, 15 genera, and 138 species in the Indian subcontinent alone. Species within Scymninae exhibit morphological characteristics distinct from other coccinellid subfamilies, including specific arrangements of coxal lines and genitalia structures.

  • Scymnus americanus

    American scymnus lady beetle

    Scymnus americanus is a small lady beetle in the family Coccinellidae, commonly known as the American scymnus lady beetle. It is one of numerous species in the genus Scymnus, a group often referred to as dusky lady beetles due to their typically subdued coloration compared to the more familiar brightly colored lady beetles. The species is documented from North America, with records from Ontario and Québec in Canada.

  • Scymnus apicanus

    apicanus lady beetle

The species is known from North America and has two recognized subspecies: S. a. apicanus and S. a. pseudapicanus. Like other members of its genus, it is presumed to be a predator of small soft-bodied insects, though specific ecological studies are limited.

  • Scymnus caurinus

    northwestern lady beetle

    Scymnus caurinus, commonly known as the northwestern lady beetle, is a species of dusky lady beetle in the family Coccinellidae. It is a small predatory beetle native to western North America, with records from the Canadian provinces of Alberta, British Columbia, and Saskatchewan. As a member of the genus Scymnus, it belongs to a group of lady beetles generally associated with aphid predation, though specific prey relationships for this species remain poorly documented. The species was described by Horn in 1895.

  • Scymnus difficilis

    dusky lady beetle

    Scymnus difficilis is a minute lady beetle in the family Coccinellidae, described by Casey in 1899. Adults measure approximately 1.8–2.1 mm in length.

  • Scymnus horni

    dusky lady beetle

    Scymnus horni is a small lady beetle (family Coccinellidae) first described by Gorham in 1897. It is classified as a 'dusky lady beetle,' a common name applied to several Scymnus species with generally dark or inconspicuous coloration. The species has a notably broad geographic distribution spanning three distinct regions: Central America, North America, and Oceania. Like other members of Scymnus, it is presumed to be a predator of small soft-bodied insects such as aphids and scale insects, though specific prey records for this species are not documented.

  • Scymnus iowensis

    Iowa lady beetle

    Scymnus iowensis, commonly known as the Iowa lady beetle, is a small species of dusky lady beetle in the family Coccinellidae.

  • 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.

  • Scymnus marginicollis

    dusky lady beetle

    Scymnus marginicollis is a species of dusky lady beetle in the family Coccinellidae, first described by Mannerheim in 1843. It is recognized as a member of the subfamily Scymninae, a group of small lady beetles often referred to as 'dusky' or 'scymnine' lady beetles due to their typically dull coloration compared to the brightly colored Coccinellinae. The species is known to occur across North America with two recognized subspecies: S. marginicollis marginicollis and S. marginicollis borealis.

  • Scymnus nebulosus

    Nebulous Lady Beetle, dusky lady beetle

    Scymnus nebulosus, commonly known as the nebulous lady beetle, is a small dusky lady beetle in the family Coccinellidae. It is found in North America and Oceania. The species is part of the Scymnus genus, which includes numerous small predatory beetles often referred to as dusky lady beetles due to their typically dark or dull coloration compared to the more brightly colored lady beetles in other genera.

  • Scymnus nevadensis

    Nevada lady beetle

    Scymnus nevadensis is a small dusky lady beetle in the family Coccinellidae, commonly known as the Nevada lady beetle. The species was described by Weise in 1929. It is known from North America, though specific details about its biology and ecology remain poorly documented.

  • Scymnus tenebrosus
