Mixed Strain
A mixed strain discoid roach colony is a group of Blaberus discoidalis assembled from more than one source or line. This large tan to brown tropical roach is widely cultured as a feeder insect for reptiles, amphibians, arachnids, and insectivorous birds, and also kept by some invertebrate hobbyists. Adult discoids have wings but do not climb clean smooth plastic or glass well, and the pale white stage seen after molting is temporary rather than a color morph.
Mixed strains are useful when production, vigor, and feeder size matter more than preserving a locality or selected line. Colony management centers on warmth, ventilation, dry stacking material such as egg flats, and a steady supply of grains, vegetables, and safe moisture that will not drown nymphs. New stock should be quarantined before mixing to limit mites, mold, and disease problems. If you sell or trade roaches for breeding, describe them as mixed rather than implying a maintained strain.
