Bucculatrix quadrigemina is a moth in the Bucculatricidae family. It is found in North America, where it has been recorded from California. The wingspan is 7–10 mm. The forewings are creamy white, more or less yellow or ocherous tinged. The hindwings are pale to dark fuscous. Adults have been recorded on wing from January to June and in October. The larvae feed on Althaea rosea. They mine the leaves of their host plant. The mine is very long and linear. Older larvae live freely, causing many holes in the leaf. Pupation takes place in a white cocoon.
