Undulambia rarissima
Munroe, 1972
Gold-lined Undulambia Moth
Undulambia rarissima is a small crambid described by Eugene G. Munroe in 1972. It is known from limited records in Florida, with active during two distinct periods: January through May and again in September. The is considered rare, as reflected in its specific epithet. Larval biology remains poorly documented, though there is tentative association with Polystichum ferns.

Identification
Distinguished from by combination of small size (13 mm wingspan), Florida distribution, and specific periods. Undulambia polystichalis, a related also associated with ferns, differs in distribution and . examination may be required for definitive identification. The specific epithet "rarissima" (meaning very rare) reflects its scarcity relative to other Undulambia species.
Appearance
A small with a wingspan of approximately 13 mm. exhibit the characteristic patterning typical of the Undulambia, which includes undulating or wavy transverse on the . The "Gold-lined" suggests pale or golden longitudinal markings.

Associated with supporting Polystichum ferns, suggesting mesic or shaded environments. Specific microhabitat requirements are undocumented.
Distribution
to Florida, United States. Known from limited collection records with no confirmed observations outside this region.
Seasonality
active January–May and September. Bimodal pattern suggests possible partial multivoltinism or cohort related to .
Diet
possibly feed on Polystichum (ferns). This association is tentative and requires confirmation.
