Ministrymon janevicroy, commonly known as the Pebbly Ministreak, is a small butterfly in the family Lycaenidae. It occurs in parts of Mexico and Central America, typically in dry forests, scrublands, and open habitats where its larval host plants grow. Adults are active during the day and are often seen perching with wings closed, which displays the cryptic underside pattern that blends well with bark or dry vegetation. Males may patrol or perch in search of females.
