Insects
of Sandbar Willow
Salix interior (Sandbar Willow)
(According to Robertson, short-tongued bees suck nectar and/or collect pollen, while other insects suck nectar. Primarily Robertson is the source of observations for staminate flowers, while observations for shrubs of this willow with unspecified gender are from Krombein et al. and Wilhelm & Rericha. Sandbar Willow often blooms later than other willows.)
