Habitat
Wetland forests, particularly bald cypress-gum (Taxodium-Nyssa) swamps and similar saturated, forested environments. Associated with standing water or seasonally flooded conditions in the southeastern United States coastal plain.
Distribution
Southeastern United States, from North Carolina south to Florida and west to Louisiana, concentrated in Atlantic and Gulf coastal plain regions.
Seasonality
overwinter and become active in spring. Multiple per year occur, with development from to adult taking approximately 30-40 days under favorable conditions. Activity extends through the growing season in warmer parts of the range.
Diet
Phloem-feeding on plant sap using .
