Argyresthia flexilis is a moth of the Yponomeutidae family. It is found in northern Montana and probably the adjacent parts of Canada.
The wingspan is about 11 mm. The forewings are yellowish-white and the hindwings are smoky. Adults are on wing in late June.[2]
The larvae feed on Pinus flexilis.[3] Late instar larvae tie needles into a bundle and mine two or more of them, starting below the middle of the needle, and mining toward the apex. The frass is ejected through the mine entrance. Full-grown larvae construct a new bundle within which pupation takes place in a dense, white cocoon.
