Lethe eurydice Massachusetts, USA Frank Model
The genus Lethe includes 113 species from temperate and subtropical regions of Asia, and 5 North American species which some workers place in a separate genus Satyrodes. Almost all species are marked with wavy lines and a series of conspicuous ocelli which on the ventral surface are centred with white. The forewings of most have concave outer margins, and elongated hindwings. Two of the North American species - appalachia and eurydice however have noticeably more rounded wings.
Lethe eurydice is distributed across the north-eastern states of the USA, and south-eastern Canada.
This species can be found in open sedge marshes and woodland / fen mosaics in the Upper Austral and Canadian zones.
The egg is greenish-white and is deposited singly in the vicinity of sedges. The larva is green with lighter and darker coloured stripes along the back and sides. It feeds nocturnally on sedges Carex and Scirpus ( Cyperaceae ). The pupa is green with lighter stripes along the abdomen, and has a large point on the thorax and prominent palpi.
Adult behaviour

The adults rarely take nectar, but are sometimes observed at sap runs, or imbibing moisture from the ground.
