''Chelone glabra'' (white turtlehead) is a plant. Its classification has in the past been controversial,〔http://vnps.org/princewilliamwildflowersociety/changes-in-taxonomy-of-chelone-glabra-and-the-traditional-scrophulariaceae-figwort-family/〕 but as a result of DNA sequence studies, it is now regarded as belonging to family Plantaginaceae (the plantain family).〔http://www.amjbot.org/content/92/2/297.full〕 ==Description== ''Chelone glabra'' is a herbaceous plant found in wetlands and riparian forests of eastern North America with opposite, simple leaves, on stout, upright stems. The flowers are white, borne in late summer and early fall. It has been used as a method of birth control by Abenaki people. Its native range extends from Georgia to Newfoundland and Labrador and from Mississippi to Manitoba.〔(【引用サイトリンク】 Chelone glabra )〕 It is the primary plant that the Baltimore Checkerspot Butterfly will lay its eggs on (although the butterfly to some extent will use a few other species).〔(''Euphydryas phaeton'' (Drury, 1773) ), ''Butterflies and Moths of North America''〕 ''C. glabra'' is also a foodplant for the sawflies ''Macrophya nigra'' (Norton) and ''Tenthredo grandis'' (Norton) (Hymenoptera: Tenthredinidae), (Stamp, 1984).〔Stamp, N.E.

''Oecologia'' 63:275–280.〕 A flea beetle in the genus Dibolia (Coleoptera: Chrysomelidae) has also been shown to feed on ''C. glabra'' (Wilcox, 1979).〔Wilcox, J.A. (1979).
