Figure 2. Pupa of the Indianmeal moth, Plodia interpunctella (Hübner). The larva crawled up two shelves and then onto a stack of food envelopes before pupating on the inside of an military C-ration toilet paper packet in the senior author's house. This shows how larvae have the ability to migrate to distance locations and thus confuse identification of the source of the infestation.
