Are angleworms eating my potatoes?
I planted several rows of red potatoes and as I dug them up, some had been eaten on. Small areas only about 1/4 inch deep. I only found three grubworms in the whole area, but lots of angleworms.

Wireworms, flea beetles, potato tuberworm and white grubs are all soil-dwelling pests that feed on potato tubers.
I doubt it is the angleworms that you mention.
