Bucculatrix tetradymiae

Bucculatrix tetradymiae is a moth in the Bucculatricidae family. It is found in North America, where it has been recorded from the Mojave desert in California.

The length of the forewings is 3.2-3.8 mm. The forewings are lustrous white with distal half dominated by roughly equal-sized postmedial and submarginal blotches partially separated by white at the anal angle and the costa. The hindwings are grey. Adults have been recorded on wing in April.

The larvae feed on Tetradymia axillmis. Young larvae probably mine the leaves, while older larvae feed externally. Pupation takes place in a white cocoon, which is fixed lengthwise against axillary spines of the host plant.
