Dioryctria sylvestrella, the new pine knot-horn or maritime pine borer, is a moth of the family Pyralidae. It is found in Europe, parts of Asia and North Africa. The adult is a small mottled brown and white insect with a wingspan of 28 to 35 mm. The moth flies in a single generation from June to October and is a pest of maritime pine and several other species of pine, on which the caterpillars feed.
The Phycitinae are a subfamily of snout moths. Even though the Pyralidae subfamilies are all quite diverse, Phycitinae stand out even by standards of their family: with over 600 genera considered valid and more than 4000 species placed here at present, they unite up more than three-quarters of living snout moth diversity. Together with the closely related Epipaschiinae, they are apparently the most advanced lineage of snout moths.
Dioryctria auranticella, the ponderosa pineconeworm moth, is a moth of the family Pyralidae. The species was first described by Augustus Radcliffe Grote in 1883. It is found in western North America from southern British Columbia south to California and Arizona, east to South Dakota and New Mexico.

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. Occasionally abundant, often in conjunction with epidemics of the spruce budworm, the spruce coneworm 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. When abundant, it can be a serious pest "particularly on white spruce".
