Protandrena (Heterosarus) subdilatipes
The flight season of Protandrena (Heterosarus) subdilatipes is June to July. Its foraging preferences are unknown, although it probably visits members of the Compositae. Little is known about its nesting habits. It is assumed that it nests in the ground as do other members of the subgenus Heterosarus.
Protandrena subdilatipes has only been recorded at the Grand Teton National Park.
Since the known population of Protandrena subdilatipes is on a National Park, the future of this bee is likely secure, although any species with such a limited distribution is at risk.
Little is known of the biology of this species. Studies of both the nesting and foraging habits would be valuable. Searches of Grand Teton National Park and surrounding areas should be done to confirm the distribution.
