Well the black wasps left and new polinators have arrived. At first I thought they were bumble bees .... but they looked small ... so I took a good look and I am pretty sure they are carpenter bees. I do have a wood privacy fence ... but my neighbor has 3 or 4 piles of wood and I think that is where they are getting there fill.
A lot of the wood is from Wisconsin where he has a "cottage" ... so I am thinking he may have delivered them in his wood piles.
The good news is this second harvest has huge raspberries and many of them! I send the SO to pick and fraternize with the bees.
I have read ... that carpenter bees are not aggressive and they fly around like they are a little drunk! So it's all good.
