Habitat
Based on the sole Astyleiopus variegatus, the is associated with deciduous forest containing red buckeye, specifically rich, moist, east-facing slopes in the southeastern United States.
Distribution
United States, with records from Vermont and the southeastern Ozark Highlands of Missouri. The distribution aligns with that of its documented plant, red buckeye (Aesculus pavia).
Seasonality
have been observed in early spring (April), based on rearing records from wood collected the previous year.
Diet
Larvae are wood-borers; the single known is red buckeye (Aesculus pavia). feeding habits are not documented.
Host Associations
- Aesculus pavia - larval Dead branches; documented in MacRae and Rice 2007 as a new larval record
Life Cycle
Complete with wood-boring larval stage. Larvae develop in dead branches and emerge as the following spring, based on rearing observations.
Behavior
Larvae bore into dead wood of plants. are associated with early spring activity.
Ecological Role
Decomposer; contributes to nutrient cycling through wood decomposition in forest .
