Habitat Preferences of Black onion fly Through Different Life Stages
The larvae of black onion fly typically reside in decaying organic matter, like compost or rotting vegetation, where nutrients are abundant for growth. In search of the larvae, one should probe into such decomposing materials. Adult black onion fly individuals are commonly found in areas with ample vegetation, particularly near fruits or flowers from which they feed on nectar. To find adult black onion fly, one could explore gardens, orchards, or fields with flowering plants during warm periods of the day when these insects are most active. Pupae are often located close to larval feeding sites, sheltered within the soil or leaf litter, requiring a careful search through these substrates to locate them.
