Comadia redtenbacheri
In 3 days ~30% in a week ~50%
Comadia redtenbacheri, also known as the agave redworm moth, is a moth in the family Cossidae. It is found in North America, where it has been recorded in Mexico and southern Texas. The length of the forewings is 12–14 mm for males and 13–16 mm for females. Adults have been recorded on wing from April to May and in September. The moth lays its eggs near the base of the Agave leaves. It is widely used in its larval form as the "worm" in mezcal. The rising popularity of mezcal could potentially subject the moth to overharvesting. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Comadia redtenbacheri is recorded against all the insects logged in Big Bend National Park (21 verified sightings from 2019 to 2026), 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.
