Spuds 2: bugs

Nice crop of spuds here drying in the sun.  Closer inspection though and a load have small (1 mm) holes in them.  I cut one open and found a long centipede-type thing inside, brown and a bit horrible.  So I'm throwing those away and find its about a third of the crop,  Nightmare. Could this be the start of the potato famine on Banner Cross Rd?  Actually I guess I could have cut out the creepy-guy and be left with most of the potato,  I'll do that next year if things get tight.
