Pedilus lugubris was found associated with Epicauta murina feeding on Lathyrus venosus foliage and with E. fabricii feeding on Lupinus perennis flowers. Epicauta cinerea and E. funebris were found feeding on foliage of Anemone canadensis and Physalis heterophylla, respectively. This is the first reported association of P lugubris with any species of Epicauta, and the first reported use of Lathyrus venosus by E. murina, of Lupinus perennis by E. fabricii, of Anemone canadensis by E. cinerea and of Physalis heterophylla by E. funebris.
