Found this to be a good description:
Red Wigglers vs Earthworms
"An earthworm eats soil. It gets it's nutritional needs from the living things in the soil (fungi, protozoa, bacteria, etc)."...."..a red wiggler eats decaying matter. Red wigglers like manure, vegetable matter, rotten fruit, etc."...."A red wiggler worm is segmented just like a nightcrawler, but it is smaller (which is why you generally do not find it in a bait shop)."
It looks to me that you have earthworms Wayne. Probably not going to very effective at breaking the contents of your bin down for you.
