Definition
Dicallomera pumila is a species of moth belonging to the family Erebidae, subfamily Lymantriinae.
Overview
The species is placed in the genus Dicallomera, which comprises a small group of tussock moths. Records of D. pumila have been reported from parts of the Palearctic region, notably in Central Asia and adjoining areas of Eastern Europe. The taxonomic authority for the species is generally cited as (Staudinger, 1892). As with other lymantriine moths, the adult is nocturnal and is attracted to light sources.
Etymology/Origin
The generic name Dicallomera derives from Greek elements: “di‑” meaning “two” and “kallos” meaning “beauty,” combined with “mera” meaning “part” or “segment,” possibly referring to distinctive wing patterns or morphological features of the type species. The specific epithet pumila is Latin for “dwarf” or “small,” likely indicating the relatively modest size of the moth compared with related taxa. Precise historical justification for the naming has not been documented in accessible primary literature.
Characteristics
- Morphology: Accurate detailed measurements for D. pumila are not widely published. Available sources suggest a moderate wingspan of roughly 20–30 mm, with forewings exhibiting muted brownish‑gray coloration and subtle patterning typical of many tussock moths.
- Life cycle: Like other Lymantriinae, the species undergoes complete metamorphosis (egg, larva, pupa, adult). Caterpillars are expected to be setose (hairy) and may feed on a variety of deciduous shrubs, though specific host plants for D. pumila have not been conclusively recorded.
- Behavior: Adults are nocturnal and are attracted to artificial lights. Flight period information is limited; observations indicate activity during the warmer months, but precise phenology varies with local climate.

Note: Detailed biological and ecological data for Dicallomera pumila are scarce in the publicly available literature. Consequently, some aspects of its description are based on inference from closely related taxa, and accurate information is not confirmed for those points.
