FIELD GUIDE DESCRIPTIONS: Beadle and Leckie (2012) under Eucosma tocullionana. ONLINE PHOTOS: TECHNICAL DESCRIPTION, ADULTS: TECHNICAL DESCRIPTION, IMMATURE STAGES: de Groot, P. 1998.

ID COMMENTS: The pale orange fascia in the median area is edged with silver. Also note the pale orange scales on the dorsum of the head.

DISTRIBUTION: In North Carolina, Pinus strobus is largely restricted to the Blue Ridge and upper Piedmont, although scattered populations are known farther to the east. All of our records for E. tocullionana are within the general range of < i>P. strobus.

FLIGHT COMMENT: Adults in North Carolina have mostly been collected in late April through mid-May, during or shortly after pollen is shed. We have one record in July. This species is univoltine (de Groot, 1998).

HABITAT: Eastern White Pine tolerates a wide range of site conditions and can be found in both mesic and dry forest communities. It is most frequent at low to mid-elevations in the mountains.

FOOD: Although Eastern White Pine (P. strobus) is the primary host species, specimens have been collected outside of North Carolina from spruces (Picea spp.), Balsam Fir (Abies balsamea), Eastern Hemlock (Tsuga canadensis) and Virginia Pine (P. virginiana). The use of these secondary hosts is questionable and might reflect misidentified specimens (de Groot, 1998).

OBSERVATION_METHODS: Adults are active shortly after dark and come to lights.

NATURAL HERITAGE PROGRAM RANKS: GNR [S3S5]

STATE PROTECTION: Has no legal protection, although permits are required to collect it on state parks and other public lands.

COMMENTS: Eastern White Pine reaches its southern limits in northern Georgia and populations of E. tocullionana in western North Carolina are near the southern limit of this species' range. The status of North Carolina populations is uncertain -- we have relatively few records for what should be a common species, at least based on its host plants. However, it appears to be fairly widely distributed in our Mountains and also present in the western Piedmont, indicating that it is unlikely to be limited by habitat.
