Heliozela aesella is a moth of the family Heliozelidae. It was described by Vactor Tousey Chambers in 1877. It is found in the United States, including Illinois, Iowa, Kentucky, Massachusetts, Minnesota, New York, Ohio and Wisconsin and Quebec in Canada.
Adults are on wing from late April to early May in one generation per year. The larvae feed on Vitis species. Full-grown larvae cut out a case and drop to the ground. Pupation takes place within this case after overwintering. Larvae and galls can be found in late May. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Heliozela aesella is recorded against all the insects logged in Dallas (23 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
