Biology
The larvae feed on Ambrosia psilostachya and Artemisia douglasiana. They mine the leaves of their host plant. The mines extend principally along the midrib, with irregular projections branching out on either side. The larva spins a cocoon on the densely pubescent underside of the leaf, constructed of silk, and the whitish pubescence of the leaf. Mines have been collected in October, while adults appeared in April of the following year. Adults have also been collected from June to July and September to October. There are two generations per year.
