Contacyphon setulipennis
This record describes Contacyphon setulipennis (species). Recorded family: Scirtidae. Recorded order: Coleoptera.
Identification and Appearance

Coloration is not reliable for identification; positive identification is only possible based on dissected specimens. Most of the images on the guide page here should be treated as general suggestions, not accurate identifications. Klausnitzer characterizes the species as having an elytra with a longitudinal spot, and the apex are light brown. Tetrault's characterization of setulipennis (as diffusus ) says: Apical patch very distinct and Variable in size and elytral maculation. The darker side margins of the elytra are at times confluent with the subapical oval markings. Epler's characterization of setulipennis (as C. sp.2) is: Usually yellow-brown with darker markings at base of elytra, discal area and laterally (but may be unmarked). This species' habitus is also illustrated with a photo of a specimen. Dets. Brad Barnd (mostly vouchered) Epler considers members of the Cyphon variabilis complex to be externally similar and identification is possible only by dissection appears to be the most common species of [ Contacyphon ] in Florida, based on material collected by black light also, the most widely distributed [ Contacyphon ] sp. in FL Type locality: Seneca Lake, New York

About Primitive Winged Insects: the wider group
Order-level background for Coleoptera, the group containing Contacyphon setulipennis. Species-specific details appear above.
Group overview
Coleoptera is the largest order of insects with over 400,000 described species, representing ~25% of all known animal species and ~40% of all insects. In the U.S. alone, nearly 30,000 beetle species have been identified.
Ecological role of the group
Beetles are prominent decomposers, especially in forests, breaking down dead wood and recycling nutrients. As predators, they reduce populations of pest insects. Many species are also important pollinators of flowering plants.
Economic and practical significance of the group
Beetles have major economic significance: leaf beetles (Chrysomelidae) and weevils (Curculionoidea) are among the most destructive agricultural pests globally, costing billions annually, while predatory species like ladybugs provide natural pest control.
