In males of Isochaetes beutenmuelleri the strongest marking is a orange round spot toward outside edge of the forewing; this spot is surround by a darker color. A male is pictured.
Females are darker overall, and have the round spot brown and the surrounding area darker brown (Covell, 2005).
The larvae go through eight instars, and feed on oak and beech leaves, leaving a "shiny silken runway" as they go (Wagner, 2005).
