Name: Todd Thiesen Eastern Washington (Zone 7a) Keep movin on.
I have a cane borer in my raspberries. It is not the "raspberry cane borer" as the double row of holes is absent. I suspect crown borers as I caught this gal hanging on a leaf. But the etymology seems wrong. The larvae are eating their way up the cane. Not down. My understanding is the crown borer just hangs out in the crown, not up to the very tips of the canes, where I found these guys. Suggestions anyone?
