Guides
Aulonothroscus
Aulonothroscus is a genus of small false click beetles (family Throscidae) containing more than 20 described species. These beetles belong to the superfamily Elateroidea but lack the prominent clicking mechanism of true click beetles (Elateridae). The genus was established by Horn in 1890 and has been documented primarily in northern Europe and Scandinavia based on available distribution records.
Aulonothroscus constrictor
small false click beetle
Aulonothroscus constrictor is a small false click beetle in the family Throscidae, characterized by the ability to flex and snap its body to produce a clicking sound similar to true click beetles (Elateridae). The species is native to North America and has been recorded across a broad geographic range including Canada and the United States. Like other members of Throscidae, it is a small, compact beetle with clubbed antennae.
Aulonothroscus punctatus
Aulonothroscus punctatus is a species of small false click beetle in the family Throscidae. The species is found in North America, with distribution records from Ontario and Québec in Canada. Very little detailed biological information has been published for this species.
Aulonothroscus validus
false click beetle
Aulonothroscus validus is a small false click beetle in the family Throscidae, first described by LeConte in 1868. Adults measure 2.5 to 5 mm in length. The species is distributed across North America, with records from Canada and the United States.
Throscinus schwarzii
Throscinus schwarzii is a species of small click beetle in the family Throscidae. Members of this family are generally minute to small beetles with clubbed antennae and a compact body form. Throscinus species are among the less commonly encountered throscids in North America.
Trixagus carinicollis
Trixagus carinicollis is a small false click beetle in the family Throscidae. It is found in North America, with records from Canada including Alberta, British Columbia, and New Brunswick. The species was described by Schaeffer in 1916.
Trixagus chevrolati
false click beetle
Trixagus chevrolati is a small false click beetle in the family Throscidae. The species is known from Central America and North America, with records extending into British Columbia, Canada. As a member of Throscidae, it belongs to a group of beetles commonly referred to as false click beetles due to their superficial resemblance to the click beetles (Elateridae), though they lack the prosternal spine and mesosternal notch that produce the characteristic clicking mechanism. The family Throscidae is relatively small and poorly studied compared to related families.
Trixagus mendax
Fake Californian Throscid Beetle
Trixagus mendax is a small false click beetle in the family Throscidae. It is native to North America, with records from the United States and Canada. The species was described by Horn in 1885. As a member of Throscidae, it belongs to a group of beetles often referred to as false click beetles due to their resemblance to Elateridae, though they are not closely related.
Trixagus sericeus
Silken Throscid Beetle
Trixagus sericeus is a small beetle in the family Throscidae, commonly known as the Silken Throscid Beetle. The species was described by LeConte in 1868 and occurs in North America, with records from British Columbia and other regions. Like other throscid beetles, it belongs to a group of small, often overlooked beetles associated with decaying wood and fungal habitats. The specific epithet 'sericeus' refers to the silky appearance of the integument.
