Specimen type: Photograph
Observation notes: None.
Status: Resident

Coordinator notes: Difficult to determine the species with 100% confidence, however according to a recent study in 2016 (Schmidt and Layberry), the timing, location, and ventral hindwing marginal/submarginal markings are most c/w C. lucia, although could be C. ladon or an early C. neglecta. The range limit of C. ladon in the study was along the far southern border of Ontario, and were limited to only a few individuals. The darker hindwing markings usually aren’t present in C. neglecta, favoring C. lucia, since their ranges overlap where your sighting was located. -jmgesell
