Southern Rocky Mountain Orangetip
Anthocharis julia

Observation date: June 02, 2022
Submitted by: Cascade Colors
Specimen type: Photograph
Observation notes: Did this used to be called Sara Orangetip, or was the Sara Orangetip split into multiple species? I have a butterfly field guide and the 'Sara Orangetip' is the only one listed for this region.
Status: Resident

Coordinator notes: Yes...these orange-tips use to be known as Sara (A. sara julia) but they are evidently genetically distinct and know name the Julia Orangetip. Another species occurs in the canyon and plateau country in western Colorado, related to Sara...this is Thoosa although the genetic evidence is less supportive of separation from Sara. Not a very common butterfly in the Front Range Foothills...very local. Mike
