This habitat/food is clearly top notch for these worms since this is also where I’ve seen some pretty amazing densities as well (although I’ve had pretty good luck in my own systems too). The absolute BIGGEST Red Worms I’ve seen (more like 4 or 5 inches) were living in various old outdoor manure (horse manure + stall bedding) heaps. There are two main factors that seem to play a role: 1) Nutrition, and 2) Moisture content. Red Worms are quite small in general, but 1 inch would definitely be below the adult average (likely more like 3 inches). I have rabbit manure in there and also feed them fermented vegetable scraps in hopes they will grow by fishing season. What am I doing wrong, I have just built a large 4ft x 8 ft x 12 inche bin for them in hopes that they were just crowded. I have noticed in raising my red wigglers, I have plenty of them but they just won’t get very large, maybe 1 inch long. My favorite are the red wigglers cause they are a better size to fish with, the others grow too big for my hook. The genus Microchaetidae is classified and grouped through a key that details anatomic features of each genii.Bentley, I currently have red wigglers, european night crawlers, african night crawlers and alabama jumpers. In 1886, Benham accepted the change in taxonomy “as valid for the species described by Rapp, and relegated the original name microchaetus to the synonymy of rappi”. Originally classified as Lumbricus microchaetus by Rapp, it was proposed by Beddard in 1886 that the name should be changed to Microchaetus rappi and “the specimen previously described by Rapp should also be recorded under this new name”. microchaetus.Īccording to Plisko, taxonomic problems in regards to M. In the same paper, Beddard requested and received specimens of large earthworms for careful dissection and study.Īfter dissection, he decided that the species of worm should be Microchaeta rappi rather than L.
