Species Scardia amurensis - Hodges#0311.1

0311.1

Scardia amurensis Zagulajev, 1965

"Though highly variable in size, amurensis specimens are very large with a wingspan of up to 40 mm." (1)

"The forewing cream marking are extended along the entire length of the dorsal margin and over the terminal area; the terminal margin has a few rusty-brown spots" (1).

Palearctic in origin: Amur and Primorskii Regions in far-eastern Russia, Japan, possibly adjacent parts of China (Robinson 1986; Baryshnikova 2008). In North America, it occurs in the eastern United States. Landry et al. (2013) include records from Texas, Mississipi, Georgia, North Carolina, South Carolina, Maryland, New Jersey, and West Virginia (1). Additional records from Tennessee and Ohio on BugGuide. MPG includes records of Daviscardia coloradella from Indiana and Maine, but these almost certainly represent misidentifications of Scardia amurensis (2).

"Fomes fungi (Robinson 1986) and possibly other bracket fungi. One specimen from Maryland reared from Globifomes graveolens growing on fallen Fagus grandifolia (USNM) (1).

"This species was initially discovered mixed among specimens of the Nearctic Scardia anatomella (Grote, 1881) in the USNM, while selecting specimens of the latter for barcoding. Careful examination of additional anatomella revealed several older records of S. amurensis from the southeastern U.S., with the earliest from eastern Texas in 1967 (USNM). Thus the introduction of this species into North America took place several decades ago, but the species has remained unrecognized. The species may be common in other U.S. collections, though misidentified, as evidenced by series collected in the 2000s in Georgia (ADAM) and in Maryland (USNM)" (1).
