The Great Eastern Silverstripe is an orange, black-spotted fritillary butterfly of eastern Asia. It doesn't live in the United States; it's found in the Russian Far East, northeastern China, Korea, and Japan. It looks very much like the Pallas's fritillary (Argynnis laodice), but its forewing tips stick out more sharply.
