(Banks, 1901)

moth fly

Pericoma signata is a of moth fly in the Psychodidae, described by Banks in 1901. It is found in eastern North America. The wing length measures approximately 2 mm. Like other moth flies, are characterized by their hairy bodies and wings, giving them a -like appearance. The species belongs to a family commonly associated with moist and organic matter.

Identification

Pericoma signata can be distinguished from other moth flies by its small size (2 mm wing length) and its documented occurrence in eastern North America. Definitive identification to level in the field is challenging and typically requires microscopic examination of morphological features such as wing venation, genitalia, and specific setal patterns. The Pericoma is part of the Psychodinae, which can be separated from other psychodid subfamilies by features of the wing venation and structure.

Appearance

have a wing length of 2 mm (0.079 in). As a moth fly, the body and wings are covered in dense setae (hairs), creating a fuzzy, -like appearance. The wings are typically held roof-like over the body when at rest. Coloration and specific pattern markings for this are not detailed in available sources.

Habitat

Specific preferences for Pericoma signata are not documented. Moth flies in the Psychodidae generally inhabit moist environments including stream banks, seeps, drains, and areas with decaying organic matter. Larvae typically develop in wet substrates rich in organic material.

Distribution

Eastern North America. The was described from this region and documented occurrences are limited to this geographic area.

Ecological Role

As a member of Psychodidae, the likely contributes to nutrient cycling through larval processing of organic matter in moist . may serve as prey for small . Specific ecological roles for this species are not documented.

Human Relevance

No direct human relevance documented. Moth flies are generally considered nuisance pests when they occur in large numbers near human structures, particularly in bathrooms and drains where larvae develop in biofilm. Pericoma signata is not specifically noted as a pest .

Similar Taxa

Other Pericoma species share the general moth fly of hairy bodies and wings, small size, and similar preferences. Microscopic examination is required for definitive separation.
Other Psychodidae genera (Telmatoscopus, Psychoda, etc.)These share the -level characteristics of -like appearance and small size. They can be distinguished by features of wing venation, antennal structure, and genitalia.
