Dioryctria reniculelloides, the spruce coneworm, is a moth of the family Pyralidae. The species was first described by Akira Mutuura and Eugene G. Munroe in 1973. It is found from Nova Scotia to Alaska, south in the east to New York, and south in the west to California and New Mexico. It was recorded from China in 2009.[One New Species and Three New Reco Rd Species of the Genus Dioryctria Zeller In China (Lepidoptera , Pyralidae , Phycitinae)] Occasionally abundant, often in conjunction with epidemics of the spruce budworm, the spruce coneworm (Dioryctria reniculelloides Mutuura & Munroe) occurs through most or all of the range of spruce in North America, feeding on new foliage and cones of spruce, and often balsam fir (Ives & Wong 1988).Ives, W.

[Coates et al. 1994] When abundant, it can be a serious pest "particularly on white spruce" (Hedlin et al. 1980).Hedlin, A.F.; Yates, H.O.; Tovar, D.C.; Ebel, B.H.; Koerber, T.W.; Merkel, E.P. 1980.
