(insect activity is unspecified; information is limited to bees; observations are from Smith et al.)
Anthophoridae (Eucerini): Melissodes communis communis (Smh), Svastra obliqua (Smh)
Members of the genus, commonly known as rosinweeds, are herbaceous perennial plants growing to 0.5–4 m tall, with yellow (rarely white) flowerheads. The name of the genus comes from the Ancient Greek word for a North African plant whose identity has been lost, though it is known its gum or juice was prized by the ancients as a medicine and a condiment.
