The eastern pine looper, Lambdina pellucidaria, is a species whose immatures feed as loopers on yellow pine needles. It is also called the pitch pine looper and the yellow-headed looper. The loopers are mottled brown and gray with brown and gray mottled stripes along the body. The head is realtively large and has brown and black spots. The first three pairs of legs are yellowish. The two pairs of abdominal legs are mottled. These caterpillars grow to about 11/4 inch long and crawl about with a looping motion. Eastern pine loopers occur from August to November. When mature, the caterpillars descend to the duff and pupate there or in soil. Pupae are relatively slender and turn dark brown. The moths are mottled brown to gray and have a darker line across the wing as well as some darker wing veins. The wingspan is up to 11/2 inch wide. The moths emerge from the pupae the following May and lay oval, pale green eggs that turn yellowish to tan eggs in batches along pine needles until the end of June. This looper is found throughout North Carolina where it has one generation per year.

Host Plants

Skip to Host Plants

Eastern pine loopers feed on pitch pine, red pine, and other hard pines. It has also been reported to feed on oak (which seems like a stretch to me). These loopers chew out only a portion of a needle, which then turns brown. If an infestation is heavy and persists for 2 or 3 years, such defoliation may kill pines.

Residential Recommendations

Skip to Residential Recommendations

Rarely do eastern pine loopers become abundant enough to even be noticed, although at times they have caused local defoliation of pines. If a specimen trees is small enough to spray, it should be possible to eliminate the loopers with a single application of a pyrethroid or another pesticide labeled for caterpillar control in residential landscapes. Such pesticides are available in the garden section of big box stores and in plant centers and nurseries.
