Banded feather-winged beetle

The Banded feather-winged beetle (Acrotrichis fascicularis) is a species in the genus Acrotrichis. It is currently classified as Least Concern on the IUCN Red List. Inhabits montane grasslands and shrublands and deserts and xeric shrublands within the Palearctic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Clouded Cosmet

Clouded cosmet refers to a microlepidopteran moth in the family Cosmopterigidae or related families, likely in the genus Mompha or Cosmopterix, characterized by wings bearing subtle clouded or mottled patterns that distinguish it from more distinctly marked relatives. Cosmet moths are small, delicate insects with narrow, lanceolate wings bearing metallic highlights and fine cross-lines. They inhabit woodland edges, hedgerows, fens, and riverbanks where their larval foodplants occur. Many cosmet moths are highly host-specific, with larvae mining leaves or boring in stems of specific plant genera such as Epilobium (willowherbs) for Mompha species or various herbaceous plants for Cosmopterix. Adults fly from late spring through summer in one or two generations depending on latitude, resting on foliage by day with wings folded roof-like over the body. The intricate wing patterns and metallic scale patches of cosmet moths make them objects of particular interest among lepidopterists, though their small size demands close examination under magnification for confident identification. Many species are locally distributed and associated with specific habitat types.
