The family Yponomeutidae are known as the ermine moths, with several hundred species, most of them in the tropics. The larvae tend to form communal webs,[1] and some are minor pests in agriculture, forestry, and horticulture. Adult moths are minor pollinators.
- Certain members of the unrelated snout moths (Pyralidae) are also known as "ermine moths." Spilosoma lubricipeda is an unrelated moth with the common name "white ermine."

Taxonomy
The traditional morphology based taxonomy of Kyrki (1990) divided Yponomeutidae into six subfamilies, but this circumscription is not found to be monophyletic in molecular phylogenetic analyses.[2][3] van Nieukerken et al (2011) split off Praydidae, Attevidae and Argyresthiidae as separate families, and Sohn (2013) elevated Scythropiinae to family to contain Scythropia.[2][3]
The two remaining subfamilies are:[2]

Characteristics
Ermine moths are small to medium-sized moths varying in wingspan from 8 to 31 mm (0.3 to 1.2 in). The heads mostly have smooth scales, the haustellum is naked and the labial palps are curved upwards. The maxillary palps usually consist of one or two segments. The wings are long, often with fringes on the trailing edges of the hindwings. The colour is usually white, pale grey or drab, often with many dark speckles.[4]
Adult ermine moths are mostly nocturnal.
The larvae are leaf-webbers, leaf skeletonizers, leafminers or needleminers and are found on a variety of host plants. Some cause economic damage to crops and trees.[4]

Etymology
The word Yponomeutidae comes from the Ancient Greek ὑπό (ypo) meaning under and νομός (nomós) meaning food or dwelling, thus "feeding secretly, or burrow".[5]
