Having identified that a wormery contains worms the next thing to consider is which worms are best suited to living there. There are over 8,000 species of worm across the globe and they live almost anywhere except where it is very hot, very cold and very dry. Compost worms have certain characteristics, both biological and ecological, which make them more suitable to living in a wormery colony. These characteristics include being; tolerant to being handled surface dwellers that don't mind their habitat being disturbed regularly able to cope with changes to temperature highly reproductive, otherwise you will have a long search for enough worms able to consume a large volumes of food relative to their size
Eisenia fetida or Rubellis terrestris - the Tiger Worm, also known as Brandling or Redworm, are normally the type of worm found in a wormery. If you have a compost bin, you will probably have seen Tiger Worms in there, especially around the top. They are pinkish/red in colour with a distinctive striped appearance, the red being separated by yellow/beige bands. You may also find Eisenia Andrei, similar to the Tigerworm but of a uniform red colour, and Eisenia rubellus Dendrobaena venata Lumbricus rubellus (Redworms).
Other creatures and unusual things crop up in the wormery as well. Amongst other things you will find Nematodes, which look like small white strings. They are not harmful and will form part of the microculture. You should also see orange worm egg capsules which are 1-2mm and each hatch about 5 baby worms. It's a nursery too!
When you buy a brand new wormery your supplier will supply you with the worms as well. If you build your own or buy a second hand wormery and need to find some worms to start a new colony a good place to look is in a compost heap or to pay a visit to your local farm or stables, worms love manure!
