Field observations on the natural history and development of Eubulus parochus (Herbst) in north central Vermont, U.S.A. are described. The weevil's associations with its host tree, butternut (Juglans cinerea L.), and the fungus causing mortality of the tree throughout its range in North America are discussed. Decline of butternut may threaten the future existence of E. parochus. Alternative host tree species are unconfirmed, but suspected, since the weevil's reported geographic range extends beyond the range of J. cinerea.
