An email from a grape grower a few weeks ago helped solve a mystery I posted about a few years ago--what caused tunnels moving in from the tips of blackberry canes. Small native bees were present in grape vines along with their larvae.
This interesting observation made me wonder...are we creating native bee habitat when we prune perennial crops? It would be interested to see if there's a positive effect on twig dwelling bees in these fields!

We've posted lots of information about blueberry pollinators at the Entomology Portal, including results from our experiments over the last several years.
Which bees are the best blueberry pollinators?
Does bee diversity change how pollinators behave in blueberries?
