Life cycle ⁷

Appears to be two to three generation a year in the Prairie Provinces of Canada. Eggs are laid in the soil near germinating seeds or where there is an abundance of decaying vegetative matter. They hatch at temperatures as low as 10˚C. The larvae is extremely polyphagous attacking a wide range of host plants that include bean,corn,melon,maize,etc. After about one to two weeks, the larvae are fully developed and pupariate in the soil. Metamorphosis in the puparium lasts 1-2 weeks .Upon completion of two to three generations it over winters in puparium.
