Douglasiidae
family of insects

Douglasiidae is a small Lepidopteran family. It includes around 32 species of micromoth whose adults are collectively called Douglas moths, after British lepidopterist and hemipterist John William Douglas. The largest genus in the family is Tinagma. They are primarily found in the Palearctic realm, with some Nearctic species. 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.
Genera
There are three extant genera:
Klimeschia Amsel, 1938 – Palearctic
Protonyctia Meyrick, 1932 – Ecuador
Tinagma Zeller, 1839 (=Douglasia Stainton, 1854) – Palearctic and Nearctic
One genus is known from the fossil record:
†Tanyglossus Poinar, 2017 Cenomanian, Burmese amber, Myanmar; its placement in the family Douglasiidae was contested by Yagi (2026).
Begin with the source’s own compact description: “Douglasiidae” is family of insects. The dossier treats that line as a proposition to test through Douglasiidae, family and insects, not as a finished interpretation.
Why this record matters
The phrase “family of insects” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 8, 2026. The linked authority identifier is Q1078371. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1938, 1932, 1839 and 1854.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
