Berosus aculeatus
Berosus aculeatus is a species of hydrophilid beetle first described by John Lawrence LeConte in 1855. It is native to the eastern United States and Cuba, with records spanning from Florida to New England and west to Iowa and Wisconsin. The species is distinguished by its prolonged elytral apices—a diagnostic morphological feature. Like other members of the genus Berosus, it is associated with aquatic or semi-aquatic habitats, though specific ecological details remain poorly documented.
