Lysimachia (Accessed 2/2015).

Frequency in NYC: Infrequent. 

Origin: Native. 

Habitat: Swamps, moist to wet, part-shade of undisturbed open woods. 

Notes: Pollen and oils from petal glands used by the melittid bee Macropis nuda (Macropis steironemati?) to provision larva, however these bees are apparently rare (Cane et al. 1983). The Halictid bee Lasioglossum versatus also collects pollen. Larvae of the blurry-patched nola moth, Nola cilicoides (Noctuidae), feed on fringed loosestrife (Hilty 2006
