Contarinia undescribed-species-on-milkweed
An undescribed species of gall midge in the Contarinia ( Cecidomyiidae) that forms galls on milkweed plants (Asclepias spp.). The has not been formally described in scientific literature but has been documented in field observations. As with other Contarinia species, it likely has a narrow association with milkweed. The informal designation indicates ongoing taxonomic work is needed.

Identification
Cannot be reliably distinguished from other Contarinia without examination of genitalia or larval . Field identification relies on association with distinctive milkweed galls and plant confirmation. Formal description and diagnostic characters have not been published.
Habitat
Associated with milkweed plants (Asclepias spp.), which occur in prairies, meadows, roadsides, and disturbed open across North America. Specific microhabitat preferences within these systems are unrecorded.
Distribution
Documented from milkweed where observed; precise range undefined due to undescribed status. Likely restricted to regions where Asclepias occur in North America.
Diet
Larvae feed internally within milkweed tissues, inducing gall formation. Specific feeding mechanics and tissue preferences unrecorded.
Host Associations
- Asclepias - induces galls on milkweed plants; specific Asclepias unconfirmed
Life Cycle
As with other Cecidomyiidae, likely has complete with , larva, pupa, and stages. Larval development occurs within milkweed galls. Specific duration of stages and number of per year unknown.
Behavior
are likely short-lived and weak-flying. Larvae are sedentary within galls. Mating and oviposition unrecorded.
Ecological Role
Acts as a gall-forming herbivore on milkweed. Galls may alter plant resource allocation and provide microhabitats for other organisms. Specific ecological impacts unstudied.
Human Relevance
No documented economic or agricultural significance. Potential interest for milkweed conservation and monarch butterfly management, though impacts on plant unknown.
