Scott- We generally went with NABA common names. Note that M. gryneus was once a separate species. However, siva and gryneus have been found to hybridize in w. Texas and New Mexico. Most now consider siva to be a subspecies of gryneus. Both NABA and the USGS site give gryneus the common name of Juniper Hairstreak. I guess that makes sense since all the host plants are from the genus Juniperus. But, it is confusing. Perhaps they should have adopted Juniper Hairstreak for the siva subspecies and leave Olive Hairstreak for gryneus.
