Osmia 4 wks in
The BOBs, Blue Orchard Bees, are hard at work. After 4 weeks they've already complete 7 new tubes of larvae. Interestingly, for four so far, they cleaned out the natal tubes and are using them again. In addition the BOBs took over one of the O. californica tubes. Hmm... not sure how that will work out in the end. These bees only work for 6-8 weeks so you want them to work the blooms on the fruit trees. Our citrus have a very large number of blooms. Unfortunately, the plum tree isn't doing as well. The jasmine is blooming as are the tall, purple irises.
