Species of the Week: The Pearl Crescent

Photo by Sarah Wray

This week’s #SpeciesOfTheWeek is the Pearl Crescent (Phyciodes tharos). Commonly found throughout the park, they get their name from a dark marginal patch containing light crescents on their hindwing. Pearl Crescents are commonly mistaken for Northern Crescents, as they were considered the same species until quite recently. Pearl Crescents do, however, have more black markings on their hindwings in comparison to Northern Crescents, which have more orange. A fun fact about the Pearl Crescent is that three different generations of this butterfly emerge every year in Ontario! This Pearl Crescent was spotted near the McParlan House, so be sure to keep an eye out when hiking along Hogg Bay!
