Very few with left with buds or open flowers.
This cactus was infected with a bacteria/fungus. Notice the necrotic areas around the areoles - second photo.
Extra-floral nectar was attracting a variety of insects - more than any neighboring cholla w/o infections. In the photo an odorius ant and a sap beetle are taking sweet exudate from the flower bud.

This buckhorn cholla was very active with a variety of insects apparently due to copious extra-floral nectar production. This may have been in response to insect or pathogen activity.

I found this bee apparently excavating a gallery into a branch of cholla. But I saw it leave several times and return so I think it was gathering resin/sap for use in its nest construction nearby. The cactus, Cylindropuntia acanthocarpa was infected with a bacteria/fungus. Notice the necrotic areas around the areoles. In response the plant was producing excess extra-floral nectar and also perhaps the resin material being gathered by the bee.
