Eteobalea sexnotella
(Chambers, 1878)
Eteobalea sexnotella is a small in the Cosmopterigidae, native to North America. are active from January and March through September, with a wingspan of approximately 17 mm. The is notable for its larval association with two Trichostema plant species, where larvae develop within stem galls.

Images
Appearance
A small with a wingspan of approximately 17 mm. Specific coloration and pattern details are not documented in available sources.
Habitat
Associated with plants Trichostema dichotomum and Trichostema suffrutescens, which occur in various open in eastern North America. The larval stage develops within stem galls on these plants.
Distribution
Recorded from New Hampshire south to Florida, west to Arkansas and Texas, and north to Ontario, Canada.
Seasonality
active in January and from March through September. Larval activity within stem galls presumably overlaps with or precedes adult periods, though specific timing is not documented.
Diet
Larvae feed on Trichostema dichotomum and Trichostema suffrutescens, developing within stem galls. feeding habits are not documented.
Host Associations
- Trichostema dichotomum - larval plantlarvae develop in stem galls
- Trichostema suffrutescens - larval plantlarvae develop in stem galls
Life Cycle
Larvae develop within stem galls on plants. Details of , pupal, and longevity are not documented.
Behavior
Larvae induce and inhabit stem galls on plants. activity spans multiple months with a notable January record.
Ecological Role
As a gall-forming herbivore, larvae modify plant stem tissue, potentially affecting plant growth and providing microhabitat for associated organisms.
