Tychius picirostris
This record describes Tychius picirostris (species). Recorded family: Curculionidae. Recorded order: Coleoptera.
Identification and Appearance
Length 1.8-2.4 mm. The upperside is covered in grey hair-like scales but if worn the black body beneath darkens the appearance. Distinguished from other species in the genus by the antennal funiculus having only 6 segments (7 in other Tychius species). Unless identified by a recognised expert, photographic evidence is required and the specimen should be examined with a microscope. In the comments box, state the key or ID method used. Note the beetle's size and describe the identifying characters. It is advisable to retain the specimen in case further checks are needed. Develops in flower heads of Trifolium species.

About Primitive Winged Insects: the wider group
Order-level background for Coleoptera, the group containing Tychius picirostris. 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.
