On the Internet and in the literature you will find a lot of (sometimes contradictory) information about two different types of compost worms: the Eisinia Fetida and the Eisinia Hortensis. In this table I try to get all the information in a row. Will you help me to separate the wheat from the chaff and make the overview complete and accurate?
