Pyrrhalta is a genus of beetles in the leaf beetle family, Chrysomelidae. Species are distributed throughout much of the world, including much of the Northern Hemisphere and the Australian region.

== Description == Pyrrhalta is a genus of leaf beetles within the subfamily Galerucinae of the family Chrysomelidae, distributed across the Holarctic, Oriental, and Australian regions.  Members of this genus are characterized by an elongated body shape, typically measuring between 4.5 and 6.5 mm in length. The coloration varies among species, often presenting hues ranging from yellowish to brown, with some exhibiting distinctive markings on the elytra. The head and thorax are generally covered with fine, dense hairs. The antennae are moderately long, usually extending to about half the body length, and are filiform in structure. The legs are slender, adapted for clinging to foliage, with tarsal claws that may exhibit a bifid structure. The pronotum is typically narrower than the elytra and may display punctate or smooth textures, depending on the species.
