Radish showing egg. winter also as adult flies, hibernating in sheltered nooks about the field and in outbuildings. As the warm days of spring advance, the flies emerge from their hibernating quarters and also from the pupal cases in the soil, and seek their host plants for the purpose of egg deposi- tion. The eggs are deposited close about the plant, the female fly working herself down below the surface, if the soil will permit, and placing the egg right against the plant root (see Pig. 3). The eggs are often placed above ground on leaves or developing buds.
