- Eudesmia menea(Lunar Eudesmia)
Eudesmia is a of lichen moths in the subtribe Eudesmiina of the Erebidae. The genus was erected by Jacob Hübner in 1823 and contains approximately 15 described distributed primarily in the Americas. These belong to the Arctiinae, a diverse group known for aposematic coloration and chemical defenses. The genus name Eudesmia is also used in botany for a subgenus of Eucalyptus, but these are unrelated .

Identification
Members of Eudesmia can be distinguished from other Lithosiini by their placement in the subtribe Eudesmiina, though specific diagnostic morphological features for the are not well-documented in accessible sources. As lichen moths, they likely exhibit cryptic coloration typical of the group. -level identification requires examination of genitalia and wing patterns; several species have distinctive banded or spotted forewing patterns (e.g., Eudesmia quadrifasciata, Eudesmia trisigna).

Distribution
of Eudesmia occur in the Americas, with records from the southwestern United States through Mexico and into Central and South America. Specific distribution data varies by species: Eudesmia arida occurs in arid regions of the southwestern United States, while Eudesmia menea and Eudesmia ruficollis have broader Neotropical distributions.

Misconceptions
The name 'Eudesmia' is shared between an insect () and a plant subgenus (eucalypts), which are entirely unrelated taxonomically. This can cause confusion in literature searches and database queries.
