Scardia amurensis
Zagulajev, 1965
Scardia amurensis is a tineid with a trans-Pacific distribution, occurring in the Russian Far East, Japan, and eastern North America. have a wingspan of approximately 40 mm. The larvae feed on bracket fungi, specifically of Globifomes and Fomes.

Identification
Distinguished from other Scardia by geographic origin and association with the Russian Far East type locality. In North America, separation from native Scardia species requires examination; the disjunct trans-Pacific distribution pattern is notable.

Appearance
have a wingspan of approximately 40 mm. Specific coloration and pattern details are not documented in available sources.
Habitat
Associated with forested environments where fungi occur. Specific microhabitat requirements for larvae and are not documented.
Distribution
Russian Far East (Amur region, Primorskii Krai), Japan, and possibly adjacent parts of China. Introduced or native in eastern North America with records from Georgia, Maryland, Mississippi, New Jersey, North Carolina, South Carolina, Texas, and West Virginia.
Diet
Larvae feed on bracket fungi: specifically recorded from Globifomes graveolens and Fomes . feeding habits are not documented.
Host Associations
- Globifomes graveolens - larval food sourcebracket fungus
- Fomes - larval food source of bracket fungi
Ecological Role
Larval stage contributes to decomposition of bracket fungi in forest .
Human Relevance
No documented economic or medical significance. North American records suggest possible introduction via human activity, though natural mechanisms are unknown.

Trans-Pacific distribution
The disjunct occurrence in both East Asia and eastern North America is unusual for a tineid . The North American may represent an introduction, though this has not been formally assessed.
