So I was checking out my garden today, and the blueberry flowers looked a little "brown".  On closer inspection, about half of all the flowers have been cut in two places, two neat slits about 1/8" long radiating out from close to the base.  Something is obviously harvesting the nectar without entering the flower.

I'm pretty sure I don't have carpenter bees, so it's something else.  Do wasps do that?  Or whatever the things that look like small black honeybees?  I've seen both of those, as well as the usual bumble bees.  The bumblebees enter the blueberry flowers in the usual way, and pollinate.

I hope whatever it was didn't steal so much nectar that the bumblebees gave up.  I guess I'll know in a couple of weeks.

On a more promising note, this year it looks like two of my cornus mas will set fruit.  I got fruit from one last year, and liked it very much.  It would be exciting to get fruit from two and be able to compare.
