Distribution
Records indicate presence in northern Europe (Denmark, Norway, Sweden) and North America (Vermont, United States). The likely has a broader Holarctic distribution given its taxonomic affinities, but specific range documentation is incomplete.
Life Cycle
Larvae are root-maggots, developing within plant roots or stems. This is the primary known trait for the , though specific plants and developmental details vary by and remain incompletely documented.
Ecological Role
Larvae function as herbivores or stem/ root borers in their plants. Their ecological impact on plant has not been quantified.
Human Relevance
Some may be minor agricultural pests due to larval feeding on crop roots, though Chirosia is less economically significant than related anthomyiid such as Delia.
