Euphydryas chalcedona

Observation date: June 15, 2019
Submitted by: gasigr
Specimen type: Photograph
Observation notes: Flowers along 8 Dollar Mountain Road. 1 and 5/8 inch wingspan.
Status: Unknown
Verified by: Ken Davenport
Verified date: December 09, 2019
Coordinator notes: Based on Warren (2005), these were provisionally viewed as chalcedona but colon was not entirely ruled out. E. colon wallacensis largely occurs east of the Cascades and I have collected those along the East Umpqua River north of Crater Lake National Park. This individual is similar to Sierra Nevada populations.
