Listrus is a genus of soft-winged flower beetles in the tribe Listrini. [1] [2] These beetles are pollinators and often found in flowers during spring and summer. [3]
Adult Listrus are around 3 mm in body length. They are cylindrical, often gray, and sometimes have a pattern of spots on their elytra. [3]
Listrus includes the following species:
Zopherinae is a subfamily of beetles, commonly known as ironclad beetles. Together with the subfamily Usechinae, they have been treated historically as a family, but have recently been joined by several additional taxa, making the Zopheridae a much larger composite family, and the Zopherinae are now only a small component within it, consisting of seven genera in the tribe Zopherini and one, Phellopsis in its own tribe (Phellopsini).
Gymnetini is a tribe of fruit and flower chafers in the family Scarabaeidae. According to Catalogue of Life (2023), there are 32 genera in Gymnetini, mostly New World.
Acratini is a tribe of primitive weevils in the family of beetles known as Brentidae. There are about 12 genera and at least 110 described species in Acratini.
Medon is a genus of rove beetles in the family Staphylinidae. There are at least 60 described species in Medon.
Eutrichapion is a genus of pear-shaped weevils in the beetles family Brentidae. There are about eight described species in the genus Eutrichapion.
Apioninae is a subfamily of pear-shaped weevils in the family of beetles known as Brentidae. There are at least 20 genera and 80 described species in Apioninae. They feed on living vegetation and sometimes on galls, making them occasional pests or tools of biological control.
Apostasimerini is a tribe of flower weevils in the family of beetles known as Curculionidae. There are over 240 genera and nearly 1700 described species in Apostasimerini.
Linogeraeus is a genus of flower weevils in the family of beetles known as Curculionidae. There are at least 60 described species in Linogeraeus.
