Help Identifying Turnip/Oriental Greens Leaf Pest

I have an outbreak of small caterpillars on my oriental greens and turnips. They're somewhat transparent and have brownish heads, and look nothing like the typical cole crop caterpillar pest that I normally deal with in spring and summer (loopers, imported cabbageworms, etc.). At their largest, they're less than 3/8" long and quite plump. The plants are in a bed that's been under an Agribon row cover since mid-October. The bed also includes various lettuces, kohlrabi, and arugula, none of which have been affected -- just turnips and oriental greens. Any ideas?

Maybe? I did a little reading, and there are cutworm species that feed on foliage, which these guys certainly do. They do extensive damage to the leaves, and I suspect that they're nocturnal, because, during the day, I find them hiding out at the base of the stems. They seem to be endless in supply -- they've been doing damage for six or eight weeks, and I continue to see teeny tiny ones as well as the larger ones as in my photo.

handpicking works, too

Oops. Meant to add that you could cage a plant or two, allow the critters to grow to adults, then post more pictures.

I'm a long-time hand-picker. :) I'd rather spend 30 minutes picking cabbageworm eggs and caterpillars off of leaves than spend 5 minutes spraying the same leaves with bt. I really, really dislike spraying anything. That being said, these guys are virtually impossible to remove by hand because of their numbers and the fact that they start out so small and tuck themselves away so securely. At this point, I've resorted to spraying with an insecticidal soap. I'll evaluate my progress this weekend, and I may try bt, as well. The suggestion to isolate a couple of plants and let them grow is a good idea.
