Well, that is some pretty interesting information on the site posted that talks about tumbleweed. One of the most fascinating parts of it is how a species of the Witchety Grub, the cossid, can actually help to break the tumbleweed loose by borrowing into the root of the tumbleweed, and it breaks off at the hole. Have you read this site yourself, gotta do it if you haven't, fascinating. I like how the raw grub tastes like butter, but cooked tastes like pork rind. Wish I had this species of grub growing here, it would certainly be on my dinner plate. Have a great day. Cindi
