Joshua Tree NP, Riverside County, California, USA May 9, 2008 Size: BL 13-14 mm
One last gray bee, found on Desert Milkweed (Asclepias erosa) roadside in Joshua Tree NP. It is somewhat similar to #535891, but I do see differences. The wing venation is not clear. Any help with this bee is much appreciated.l
