Hence, a lot of our information on earthworm life histories goes back to these periods. This situation is not improving since the type of normal history studies that involve observations of basic biology of organisms such as earthworms are not made by naturalists as they were in the nineteenth and early twentieth century.
Other families of earthworms besides lumbricids have rarely been studied in detail but likely differ in terms of time of development.
Our knowledge of the life cycles of even quite common species of temperate and tropical species of earthworms is still very inadequate, and there are many species about which we know very little of their life cycles.
