Unknown Strain
An unknown strain house cricket is an Acheta domesticus whose source line has been lost, undocumented, or mixed beyond recognition. The insects may still be ordinary domestic house crickets, but the term gives no dependable information about growth speed, adult size, disease history, color inheritance, or suitability for large-scale production. Most will look like typical tan or brown house crickets, with occasional blackish, pale, striped, or spotted individuals depending on age, molt stage, and ancestry. It is a practical record label rather than a morph name.
Unknown-strain crickets can be used as feeders or breeding stock when they are active, well fed, and free of obvious mites, mold, or foul odor. Quarantine is useful before adding them to an established colony, since house cricket densovirus and other problems have affected feeder operations in the past. Provide a warm bin, cardboard hides, dry feed, and safe moisture, then watch hatch rate and survival before relying on the line for regular supply.
