Colaspis crinicornis

Description

Colaspis crinicornis is a species of leaf beetle in the family Chrysomelidae. It is found in Central America and 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 has 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.
