Hi When I was growing up I was told that worms would come to the surface of the ground after it rained so that they would not drown. Well , after all these years the sudden realization is that this was not true. The truth of the matter is that what they are really doing is looking for a sex partner and a nice level flat place to mate. Lumbricus terrestis is commonly known as the Nightcrawler, Lumbricus rubellus is the amazing Redworm and is nature's best composter as well as nature's best fishing bait. http://www.hky.com/~wormwrld/worms.htm http://scarab.msu.montana.edu/extension/insec010.htm The environmental requirements for the nightcrawler and red wriggler was found at the following web site . http://www.gnv.fdt.net/~windle/environ.htm The various species of earthworms have different environmental requirements which are necessary for their propagation and continued health. These requirements will inevitably dictate whether one particular "family" of worms will be suitable for culture in any given circumstance. For instance, though many people may be interested in the possibility of raising Lumbricus Terrestris (The Nightcrawler, or Dew Worm) in the house as a source of fishing bait, this is simply not very plausible when we consider that this particular worm prefers temperatures in the area of 5-10 degrees Celsius. During the heat of the day, this large member of the earthworm family retreats to the depths of his burrow, venturing out only in the late evening, or early morning, the coolest available times. (Burrows have been found to extend to a depth of over 12 feet.) Thus, if we wish to culture this animal in the confines of our homes, we will require the ability to refrigerate at least a part of the available space. Even then, however, the number of additional considerations will eventually convince most people that nightcrawlers should be "harvested" rather than "cultured." On the other hand, the two most commonly-used worms for vermicomposting, Eisenia Foetida and Lumbricus Rubellus, are the most popular precisely because of the ease in replicating the environmental conditions they prefer. Perfectly suited to an indoor existence, the culturing of these animals presents next to no problem, requiring only a minimum of effort, and presenting no hardship for those of us who share their place of residence. The fact is, in the absence of the normal hazards these worms usually face in their outdoor habitats, they are found to grow faster, stay healthier, live longer, and reproduce at an increased rate indoors. Thus, indoor culture turns out to be heaven for them, and a great benefit to the "landlord" who will have a great new way to convert his organic waste materials into a wonderful "food" for his plants, lawn, and garden. These "requirements" can be broken into three main areas, this website goes into quite a bit of detail regarding moisture, temperature and aeration. Click on the link above to learn about these conditions. Hope you enjoy the websites about worms , you will find sufficient information to answer all your questions about worms.
