Wingspan 4.5 to 6 mm. Stigmella atricapitella has a black head and dark brownish wings with a bronzy sheen. The larva mine the leaves of various oaks in two generations. The first generation produce a short gallery with frass in thick line. The second generation mine is a longer gallery with the frass in a narrower line. The larva is a whitish-yellow and has dark prothoracic sclerites (which help distinguish it from S. roborella, with a pale head only).
