Dicymolomia metalliferalis is a moth of the Crambidae family. It is found in western North America, from southern Vancouver Island and Washington through Oregon to California and western Arizona.[2]

The wingspan is about 16 mm. Adults have fine black wavy lines on the hindwings.[3]

The larvae have been recorded feeding on decaying seed pods of Lupinus species (Lupinus albifrons and Lupinus latifolius). They first feed from within a chamber of sparse silk formed in the cavity of a partially intact fruit. Later, they create purse-like cases. Pupation takes place within this case. The larvae have a salmon-orange body and a yellow-brown to red-brown head.[4] The species overwinters in the larval stage within the seedpod of hostplant.
