Criocerinae
Guides
Criocerini
shining leaf beetles
Criocerini is a tribe of leaf beetles in the subfamily Criocerinae, family Chrysomelidae. Members are commonly known as shining leaf beetles. The tribe includes at least two genera: Crioceris and Lilioceris. These beetles are herbivorous and associated with monocot plants, particularly members of Liliaceae and related families.
Lemini
shining leaf beetles
Lemini is a tribe of leaf beetles within the subfamily Criocerinae, characterized by their often metallic or shiny appearance. Members are placed in the family Chrysomelidae, a large group of herbivorous beetles commonly known as leaf beetles. The tribe was established by Gyllenhal in 1813 and contains multiple genera distributed across various regions.
Lilioceris
lily leaf beetles, air potato leaf beetles
Lilioceris is a genus of leaf beetles (Chrysomelidae) in the subfamily Criocerinae, first described by Edmund Reitter in 1912. The genus contains over 100 species, with approximately 80 species occurring in Asia. Several species are notable agricultural and horticultural pests, particularly of plants in the lily family (Liliaceae). Lilioceris lilii (lily leaf beetle) is a serious pest of native and cultivated lilies in Europe and North America, while L. cheni has been successfully deployed as a classical biological control agent against the invasive air potato vine (Dioscorea bulbifera) in Florida. Species range from 4–10 mm in length with elongated, narrow bodies and distinct shoulders between the elytra and pronotum.
Oulema
Cereal leaf beetles
Oulema is a genus of leaf beetles in the family Chrysomelidae, subfamily Criocerinae. The genus contains approximately 100 species distributed primarily in temperate to tropical regions. Several species are economically important agricultural pests, most notably Oulema melanopus (cereal leaf beetle), which has been introduced to North America and causes significant damage to wheat and other small grain crops. The genus can be distinguished from the closely related Lema by pronotum shape and the converging angle of frontal grooves.
Oulema concolor
Oulema concolor is a species of leaf beetle in the family Chrysomelidae, first described by J.L. LeConte in 1884. It is distributed across Central America and North America. The genus Oulema belongs to the subfamily Criocerinae, commonly known as cereal leaf beetles and their relatives. As with many Oulema species, detailed biological information remains limited in published literature.
Oulema elongata
Oulema elongata is a species of leaf beetle in the family Chrysomelidae, described by R. White in 1993. The species belongs to the subfamily Criocerinae, a group commonly known as cereal leaf beetles and allies. Members of the genus Oulema are typically associated with monocot plants, particularly grasses. Very few observations of this species have been documented, with only two records in iNaturalist as of the knowledge cutoff.
Oulema maculicollis
Oulema maculicollis is a leaf beetle in the family Chrysomelidae, subfamily Criocerinae. The species is native to North America. As a member of the genus Oulema, it belongs to a group of leaf beetles commonly known as cereal leaf beetles, though specific ecological details for this species remain poorly documented in available sources.
Oulema margineimpressa
Oulema margineimpressa is a species of leaf beetle in the family Chrysomelidae, subfamily Criocerinae. It was described by Schaeffer in 1933 and is known from North America. Members of the genus Oulema are commonly referred to as cereal leaf beetles, though specific ecological details for this species remain poorly documented.
Oulema palustris
Marsh Cereal Leaf Beetle
Oulema palustris is a North American leaf beetle in the family Chrysomelidae. The species is a specialist herbivore associated with thistles, with larvae functioning as leaf miners and adults feeding externally on foliage. The specific epithet 'palustris' refers to marshy habitats, though the species' exact habitat preferences require further documentation.
