Lethe ( Satyrodes) eurydice : In the summer of 2020 (July-Sept), thirty Lethe eurydice larvae were reared ex ova deposited on some Carex tuckermanii sedge plants, which had been transplanted from a drying vernal pool into containers on the author’s porch. Without exception, soon after a molt each larva turned around 1800 and devoured its shed cuticle ( Fig. 1). Typically a larva consumed its entire cuticle except the head capsule. Thereafter each larva invariably turned around again. One larva upon approaching a newly shed exuvia of another larva started eating the tail. However, this larva soon moved on, leaving most of the cuticle for the previous occupant to eat.
