Colaspis is a genus of leaf beetles in the subfamily Eumolpinae. It is one of the largest genera in the subfamily, containing over 200 species, and it is known from both North and South America. A number of species from this genus are considered to be pests, such as the grape colaspis. Some species are known from the fossil record from the Eocene of Colorado in the United States.
Colaspis pini, the pine colaspis, is a species of leaf beetle from North America. It is known to feed on pines in the southern United States, and is an occasional pest of Christmas trees. It was first described by the American entomologist Herbert Spencer Barber in 1937.
Colaspis hesperia is a species of leaf beetle from North America. Its range spans from Arizona to Texas and south to Mexico. The specific name, hesperia, is derived from the Greek for "western". It is closely related to Colaspis brunnea.
Colaspis louisianae is a species of leaf beetle from North America. It is distributed in Texas and Louisiana in the United States. It is close in appearance to Colaspis brunnea.
Tymnes is a genus of leaf beetles in the subfamily Eumolpinae. It is known from North America and Central America. There are at least nine described species in Tymnes.
Rhabdopterus weisei is a species of leaf beetle. It is found in North America. It was originally described under the name Colaspis subaenea by the American entomologist Charles Frederic August Schaeffer in 1919. However, this name was already used for a species described by Martin Jacoby in 1890, so Schaeffer renamed his species to Colaspis weisei the following year. It was later moved to the genus Rhabdopterus by Herbert Spencer Barber in 1943.
Anomoea nitidicollis is a species of case-bearing leaf beetle in the family Chrysomelidae. It is found in Central America and North America.
Colaspis arizonensis is a species of leaf beetle from North America. It is found in southeast Arizona and northwest Mexico. It was first described by the American entomologist Charles Frederic August Schaeffer in 1933.
Phratora americana is a species of leaf beetle in the family Chrysomelidae. It is found in North America.This species is known from Ontario, Quebec, and high elevations in the eastern United States of America. It feeds on willow species and varies in color from purple to blue or blue-green.
Colaspis costipennis is a species of leaf beetle from eastern North America. It is mostly found in coastal states; in the United States, its range extends from Louisiana and Georgia north to New Hampshire and Pennsylvania, and in Canada, it is reported from Ontario. It was originally described as a variety of Colaspis brunnea, but it is now recognised as a distinct species. It is included in the Colaspis suilla species group by Riley (2020).
Colaspis suilla is a species of leaf beetle. It is found in eastern North America.
Colaspidea is a genus of leaf beetles in the subfamily Eumolpinae. It is known from North America and the Mediterranean. It has recently been suggested that the Mediterranean species of Colaspidea are a sister genus to Chalcosicya, and that Colaspina forms a sister genus to the former two combined. It has also been suggested that the North American species of Colaspidea may represent a separate genus.
Colaspis viriditincta is a species of leaf beetle from North America. It is distributed in Arizona and Mexico. It was first described by the American entomologist Charles Frederic August Schaeffer in 1919. The specific name, viriditincta, is derived from the Latin for "green-tinged".
Colaspis crinicornis is a species of leaf beetle from North America. It primarily occurs in the Great Plains of the United States. It was first described by the American entomologist Charles Frederic August Schaeffer in 1933. Though it has not historically been considered a pest, population densities of the species have been increasing in corn and soybean over the last decade in southeastern Nebraska. A study has found C. crinicornis to be univoltine in the same region, and that it overwinters in soil as larvae. It has also been found that diets of corn or soybean leaves do not affect the consumption, longevity or fecundity of adult C. crinicornis.
Colaspis planicostata is a species of leaf beetle from North America. It is distributed in southern Texas and in Mexico. It is differentiated from Colaspis brunnea and related species in the United States by the color of the ventral surface, which is dark with a metallic green luster.
Colaspis pseudofavosa is a species of leaf beetle from North America. It is a post-harvest pest of blueberries in the southeastern United States, and also feeds on plants such as southern wax myrtles and pecans.
Colaspis brownsvillensis, the Brownsville milkvine leaf beetle, is a species of leaf beetle found in the state of Texas in the United States. It was first described by the American entomologist Doris Holmes Blake in 1976 from Brownsville, Texas, after which the species is named. It is a close relative of Colaspis nigrocyanea.
Colaspis viridiceps is a species of leaf beetle from North America. Its range spans from Arizona to New Mexico and south to Mexico. It was first described by the American entomologist Charles Frederic August Schaeffer in 1933.
Colaspis cruriflava is a species of leaf beetle found in the state of Arizona in the United States. It was first described by the American entomologist Doris Holmes Blake in 1977. The specific name, cruriflava, is derived from the Latin for "leg yellow".
Colaspis recurva is a species of leaf beetle from North America. It is found in coastal states, its range spanning from Virginia south to Florida west to Louisiana.
