Our summer fundraiser has arrived, and we need your help!
We depend on donations to keep Butterflies and Moths of North America online and free. If everyone who uses this resource makes a donation, we could cover our ongoing costs, develop new features, upgrade the system, and maybe even remove those pesky ads. Please make a one-time or recurring donation to show your support for this valuable source of information. Thank you!
Observation notes: Only one seen at this location, weedy stream side at forest edge, bordering large meadow. Interesting mix of Argynnii and Bolorians here, too, A atlan tis, A cybele, B bellona.

Coordinator notes: cannot be identified with certainty without examining the genitalia : This is certainly P. lupini because P. acmon only occurs in lowland coastal western U.S. All inland populations are lupini and the group is still under study. The name "Lupine Blue" is a misnomer because it does not feed on lupine, the host across its range are buckwheats (Eriogonum spp.). The habitat description fits lupini and buckwheat was likely part of the flora there. P. acmon feeds only on legumes according to Paul Opler who has been studying the group for years.
