Coastal Green Hairstreak
Callophrys dumetorum

Observation date: April 10, 2010
Submitted by: Nancy Hamlett
Specimen type: Photograph
Observation notes: On Deerweed (Acmispon glaber) at the Claremont Colleges' Bernard Field Station, in a transitional area between native sage scrub and non-native grasses. We have been calling all the green hairstreaks at the field station Callophrys affinis, but I am wondering if some (or all) of them might be Callophrys dumetorum. I am submitting photos of three different individuals, of which this is #1.

Coordinator notes: This is what was called Callophrys perplexa until the ICZN ruled that the correct scientific name is dumetorum and what was called dumetorum the Coastal Green Hairstreak goes back to being Callophrys viridis. Some believe Callophrys viridis=C. dumetorum (the two are conspecific) This seems to be ruled out in Oregon where both entities occur. Since this issue confounds even scientists and BAMONA has not yet adjusted the matter, your question was a good one!-Ken Davenport
