illapertus

Illapertus is a genus of long-horned beetles in the family Cerambycidae. The genus was first described by British entomologist Charles Joseph Gahan in 1890. The name "Illapertus" is derived from the Latin words "illa" meaning "not" and "apertus" meaning "open", referring to the closed space between the wings of the beetles.

Illapertus beetles are typically large in size, with a length ranging from 15 to 30 millimeters. They are characterized by their elongated bodies and long antennae. The beetles are typically dark brown to black in color with white markings. They are found in tropical and subtropical regions of Central and South America.

Illapertus beetles are known to feed on a variety of plant materials, including wood and plant sap. They are typically nocturnal and are attracted to light sources. They are also known to be polyphagous, meaning they can feed on multiple plant species.

There are several species within the Illapertus genus, including I. confluens, I. morosus, and I. claytoni. Each species can be distinguished by their unique color patterns and appendages. Illapertus beetles are considered to be relatively minor pests, but they can cause significant damage to certain plant species. They are often collected by entomologists and beetle enthusiasts for their unique appearance and characteristics.
