Mine got smashed around a bit, Columbus, POR & Fuggles copped the brunt of it. Squished & shredded. Will sing to them to tonight, hopefully they'll recover.
HBHB I found some of those when I pulled some rhizomes. There is a larva which feeds off hops for five years while they develop, becoming a giant beetle, but I only just read briefly about them and don't know much else. They look a bit similar but I'm not a'tall sure.
Hey HBHB, they're just witchety grubs - at least that's what we've always called them. I think you've got ones that live in wood/trees (the ones the kooris eat) and ones in the ground. I believe they generally just eat whatever crap in the ground, including dead/dying roots. If they're in higher numbers they might be savaging the roots of the hops(?). I grew up in the country and they're everywhere in the soil (country SE of Melb); and all manner of plants still grow happily in spite of them.
Hope that helps
Also - 2 weeks slack and no pics.
My Columbus (shout out to Ninegrain!) rhizomes shot out of the ground ~2 wks ago. Still pretty small, and there's no sign of the Chinook waking up yet.
