Garden Pests and Diseases: What are these worms - are they destroying my dahlia tubers?, 0 by todgor

Well something is - it wasn't particularly wet this June like the last two (which would cause rot), but many of my plants are stunted, and coming up late. Some did not come up at all, so I dug them up. Many were just empty husks, but others were filled with wet gelatinous goo, and these creepy little worms. Are the worms the cause? Or the cleanup crew after the tubers got some biological pest? What are they? The only thing I could come up with similar is cabbage maggots, but they are not supposed to be active in blazing hot weather like now.
