Coordinator notes: This is the Julia Orangetip...a male...(has gray-green marbling on the underside of the hindwing). You might find Sara (aka Southwestern Orangetip=A. thoosa) in your area also...so keep snapping photos. It has blackish-green or inky looking marbling on the underside of the hindwings. Julia is probably another new early record for the species in western Colorado. Mike
