Eubaphe mendica
(Walker, 1854)
Beggar, Beggar Moth
Eubaphe mendica, commonly known as the beggar or beggar , is a small geometrid moth to eastern North America. The exhibits a to trivoltine with active from late spring through early autumn. are specialized feeders on maple and violet species. The "beggar" likely derives from the moth's drab, worn-looking appearance.

Identification
Distinguished from similar small geometrid by its combination of small size (wingspan under 30 mm), drab brownish-gray with indistinct patterning, and pale . The worn, faded appearance is characteristic. More precise identification requires examination of or association with larval plants. Similar in the Eubaphe and related larentiines may require dissection for confirmation.

Distribution
Eastern North America. Documented from Canadian provinces including Alberta, Manitoba, and Saskatchewan, and from the United States including Vermont. The core range appears to be the northeastern and north-central United States and adjacent Canada.
Seasonality

Ecological Role
function as primary consumers, feeding on leaves of maple and violet. Their role in as for birds, , and other is likely but not quantified. They contribute to through and subsequent decomposition.
Human Relevance
No significant economic or ecological impact. Occasionally encountered by naturalists and enthusiasts. Not considered a pest of ornamental or agricultural plants despite feeding on maple. The "beggar" reflects its unassuming appearance rather than any human interaction.
