See text Douglasiidae is a small Lepidopteran family.
[2][3][4] It includes around 32 species[2] of micromoth whose adults are collectively called Douglas moths, after British lepidopterist and hemipterist John William Douglas.
[2] They are primarily found in the Palearctic realm,[5] with some Nearctic species.
[4] The adults have a 6 to 15 mm wingspan, with a reduced hindwing venation and long fringes.
The larvae are leaf miners or borers, primarily in stems and petioles, belonging to Boraginaceae, Labiatae, and Rosaceae.
