Chrysoclista
Chrysoclista is a genus of small moths within the family Elachistidae, though its familial placement has been historically disputed. The genus was described by Henry Tibbats Stainton in 1854 and contains approximately twelve described species distributed across the Holarctic region. Species within this genus exhibit metallic coloration, reflected in the name derived from Greek roots meaning 'golden' and 'hair'. The taxonomy of Chrysoclista has been contentious, with various authors assigning it to Agonoxenidae, Cosmopterigidae, Elachistidae, or Momphidae.
Epimartyria
Epimartyria is a genus of small, primitive moths in the family Micropterigidae, established by Walsingham in 1898. The genus contains three described species: E. auricrinella, E. bimaculella, and E. pardella. These moths represent an ancient lineage of Lepidoptera that retains chewing mouthparts as adults, a characteristic of the family Micropterigidae.
Eriocrania
Birch leaf-mining moths
Eriocrania is a Palearctic genus of small, diurnal leaf-mining moths in the family Eriocraniidae. Adults are active in early spring (March–May), flying in sunshine around host trees. Larvae are specialized miners of birch leaves (Betula spp.), forming large blotch mines with distinctive frass patterns. The genus exhibits pronounced population fluctuations between years and has been extensively studied for its ecological interactions, including competition with other leaf-miners and responses to environmental stressors such as urbanization and pollution.
Eriocranioidea
Eriocranioid moths
Eriocranioidea is a superfamily of primitive moths comprising a single family, Eriocraniidae, with six extant genera. These small, metallic moths are restricted to the Holarctic region and are among the earliest Lepidoptera to emerge in spring. Adults are primarily day-flying and possess a functional proboscis used for drinking water or sap. The larvae are leaf miners, predominantly feeding on trees in the order Fagales.
Heliozelidae
Shield-bearing Moths, Shield Bearer Moths
Heliozelidae are a family of small, primitive monotrysian moths in the order Lepidoptera. Adults are typically metallic, day-flying moths with shiny smooth heads and wingspans of 4–5 mm. Larvae are specialized leaf miners that feed between leaf epidermises, creating distinctive blotch or serpentine mines. A defining family trait is the larval habit of cutting oval shield-like cases from the mined leaf tissue, which are used for pupation; these shields are attached by silk to bark, leaves, twigs, or other substrates. The family has gained attention due to several invasive species that have expanded their ranges, particularly in Europe.
