Argyresthia pseudotsuga is a moth of the family Yponomeutidae. It is found in North America, including Washington.
Adults emerge in April.
The larvae feed on Pseudotsuga menziesii.[2] They mine the twigs and tips of their host plant. The larvae enter the twigs at a node mining in a spiral pattern around the new wood, or directly into the wood. They continue feeding until late fall when they move to the base of the twig and construct a pupal chamber. Pupation takes place around the end of January.[3]
