Solitary butterfly settling for seconds only on the vegetation between trees and close to the river bank.
No interactions present.
Oblita has a dark (nearly black) ground colour and pale (nearly white) markings. Tircis has a brownish colour and cream markings.
Unless it is a photographic artifact this photo looks to me like it is brown and cream which suggests tircis.
