Definition
Trichaea pilicornis is a species of moth in the family Crambidae, subfamily Spilomelinae.
Overview
- Taxonomy:
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Insecta
- Order: Lepidoptera
- Family: Crambidae
- Subfamily: Spilomelinae
- Genus: Trichaea
- Species: T. pilicornis
- Authority: The species was first described by Francis Walker in 1865.
- Distribution: Records of T. pilicornis exist from parts of the Neotropical region, including countries such as Brazil and Panama. Precise range limits are not comprehensively documented; further field surveys are required for a complete distribution map.
- Habitat: Like many crambid moths, it inhabits forested areas where host plants for its larvae are available. Specific habitat preferences have not been thoroughly studied.
Etymology / Origin
- The generic name Trichaea derives from the Greek word trich‑ (“hair”) combined with a suffix often used in zoological nomenclature, possibly alluding to the setaceous (hair‑like) scaling of members of the genus.
- The species epithet pilicornis combines the Latin pilus (“hair”) and cornu (“horn”), literally meaning “hair‑horned.” This likely refers to the moth’s noticeably pilose (hair‑bearing) antennae or other horn‑like structures observed by the original describer.
Characteristics
- Adult morphology: Adults possess a wingspan of approximately 20–30 mm. The forewings are generally pale yellowish‑white with distinct brown or grey transverse lines and a subtle discal spot; hindwings are lighter with fewer markings.
- Antennae: The antennae are filiform and bear fine setae, consistent with the implication of the name pilicornis.
- Life cycle: Detailed information on the larval stage, host plants, and phenology of T. pilicornis is not presently available in the primary literature; such aspects remain to be documented.
- Behavior: Adults are nocturnal and are attracted to light, a common trait among crambid moths.

Note: While the taxonomic placement and basic description of Trichaea pilicornis are supported by entomological databases such as the Global Information System on Pyraloidea (GlobIZ), many ecological and biological details remain insufficiently documented. Further research is required to confirm the species’ full distribution, life history, and conservation status.
