Bucculatrix mirnae

Bucculatrix mirnae is a moth in the Bucculatricidae family. It is found in the Azapa Valley in northern Chile.

The length of the forewings is 2.78–3.33 millimetres (0.109–0.131 in). The forewings are covered with light reddish-brown scales. The hindwings are creamy white.

The larvae feed on Baccharis salicifolia. They mine the leaves of their host plant. Older larvae feed externally, skeletonizing the leaves. Pupation takes place in a cocoon, mostly spun on either twigs or dry leaves of the host plant.
