Ministrymon janevicroy, the Vicroy's ministreak, is a butterfly in the family Lycaenidae. It is found from the southern United States (Texas) to Costa Rica (Guanacaste). There are disjunct populations on the Venezuelan islands of Curaçao and Isla Margarita. The habitat consists of dry deciduous forests and scrubs.
The length of the forewings is 9.1 mm for both males and females. Adults resemble Ministrymon azia, but have olive green eyes instead of the dark brown/black eyes. In Texas, adults have been recorded on wing from January to August.
The larvae possibly feed on Mimosa and Leucaena species. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Pebbly Ministreak is recorded against all the insects logged in Cumbres de Monterrey National Park (5 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.
