Hemlock, balsam fir, and white spruce are most at risk. When ideal conditions exist in mature and over-mature stands, their population builds to epidemic levels causing severe defoliation and tree mortality. Western hemlock is relatively intolerant to defoliation compared with other tree species. Similar Insects and Diseases: See New Mexico fir looper. Mature caterpillar present from August to October. The Eastern Hemlock Looper prefers fir as a host tree but it is also a defoliator of Spruce, Larch and occasionally deciduous trees like Maple, Birch and Poplar while the Western Hemlock Looper attacks Western Hemlock, Red Cedar, Spruce and Douglas-fir. The phantom hemlock looper, Nepytia phantasmaria, is sometimes unusually abundant in western hemlock looper outbreaks, and outbreaks of the phantom hemlock looper or the western black-headed budworm, Acleris gloverana, sometimes coincidentally occur at other locations. The Hemlock Looper has one generation per year and overwinters as an egg. Small numbers of hemlock looper occur naturally in all fir and spruce forests in Nova Scotia. The larger larvae are very messy feeders, moving about "nipping" foliage (which later dies) and, when disturbed, dropping from the trees onto undergrowth where defoliation is often heaviest. 18 Elkins Lane The native hemlock looper (Lambdina fiscellaria Guenée) also appears to have played a role in previous population declines of this conifer. The ground beneath heavily infested trees may also be covered with a mat of "nipped" or partly chewed needles. We consider this species to be distinct from the curve-lined looper, Lambdina fervidaria, which has a paler caterpillar that prefers to eat oaks, Quercus species.
