The logic of [breeding two different isopod genus together](https://postpods.co.uk/blogs/isopods-useful-articles/breeding-isopods-for-profit) is likely to have been carried over from other exotic hobby communities. For example, hybridising (i.e. cross breeding) in the ball python community is common and has led to many fantastic morphs being produced in the captive bred community.
Unfortunately, we are unaware of any scientific papers, articles or hobby news reporting positively that different isopod genus/species are capable of crossbreeding. While isopods are often observed attempting mating behaviors with other isopods, the act is only mechanical with no genetic success; just like a dog enthusiastically humping its favourite toy.
There are still so many gaps in our knowledge when it comes to isopod genetics alone and the interplay between their morphological and/or behavioural design appear to make different isopod genus/species incapable of hybridising. For example, the Porcellio isopod genus is very diverse with the range of species. If a P. ornatus was housed with a P. scaber nothing would happen where breeding is concerned. Even introducing a few isopods from another species rarely results in successful breeding or stable colonies.
Not only are isopods genetically different, preventing fertilization as often their genitalia are incompatible, inhibiting successful copulation. Additionally, isopods come in many different shapes, sizes, different parts of the world, have different behavioural features and tolerances. It is likely two different isopod genus/species are essentially foreign from one another. Males and females of different species often have incompatible reproductive structures, further preventing successful mating.
Cohabiting two different isopod genus/species together will likely only serve to cause one or both colonies to die off as the females may become too stress which may lead to her aborting her eggs or die due to stress. Furthermore, it may cause one type of isopod to out compete the other or lead to aggression and cannibalism. Introducing other isopods can also lead to unexpected interactions and stress within the habitat.
There are a handful of subspecies that can hybridise – the most prominent example is that of Oniscus asellus asellus and Oniscus asellus occidentalis. Both asellus asellus and asellus occidentalis have uniquely presenting penile papillae, and interestingly, the offspring of the two subspecies has penile papillae unique from either parent species!
While it may appear a fun and exciting experience to see if crossbreeding different isopods is possible, we generally recommend avoiding it. Isopods are fascinating creatures, and while crossbreeding may seem intriguing, their diversity is best appreciated by observing their natural behaviors and unique traits.
Introduction to Breeding Isopods
Breeding isopods is an exciting venture for invertebrate enthusiasts, offering a window into the fascinating world of these unique crustaceans. Isopods belong to the subphylum Crustacea and include over 10,000 different species, with terrestrial isopods being especially popular in the hobby. To successfully breed isopods, it’s important to understand their natural biology and the conditions they need to thrive. Creating a suitable habitat that mimics their environment—complete with the right substrate, moisture, temperature, and plenty of hiding places—sets the stage for breeding success. Female isopods play a vital role in the process, carrying fertilized eggs in a brood pouch until the young are ready to emerge. With careful attention to their needs, breeding isopods can be both rewarding and educational, allowing you to observe the full life cycle of these remarkable creatures.
Creating the Ideal Isopod Habitat
A well-designed isopod habitat is the foundation for a healthy, thriving colony and successful breeding. Start by providing a substrate mix that includes sphagnum moss and leaf litter, which not only offers essential hiding places but also serves as a food source. Good airflow is crucial—ventilation holes in your isopod enclosures help prevent bacteria growth and keep the environment clean. Whether you choose a plastic or glass container, maintaining a temperature between 70-80°F (21-27°C) will keep your isopods comfortable and active. Housing isopods in a suitable habitat with plenty of cover and moisture encourages natural behaviors and breeding, helping your isopod colony flourish.
Isopod Care and Nutrition
Proper isopod care and nutrition are key to maintaining a vibrant isopod colony. Isopods are natural recyclers, feeding on decaying organic matter like leaf litter and rotting wood. Supplement their diet with small pieces of fruits, vegetables, and commercial foods such as Repashy Morning Wood to ensure balanced nutrition. Always provide enough food for your isopods to finish within 24 hours, and promptly remove any uneaten food to prevent mold and bacteria growth. Fresh water and regular misting help maintain the humidity levels that isopods need. Some isopod species, like dwarf striped isopods, are especially popular for their manageable size and simple care requirements, making them a great choice for both beginners and experienced keepers.
Selecting Isopod Species for Breeding
Choosing the right isopod species is an important step in any breeding project. There are many different species of terrestrial isopods, each with their own unique traits and care requirements. Armadillidium species, such as the striking zebra pillbug, and Porcellio species, like the rough woodlouse, are favorites among breeders. Pill bugs and woodlice are also commonly bred for their hardiness and interesting behaviors. When selecting a species, consider features like differently coloured segmental plates, which can add visual interest to your colony—Porcellio silvestri females, for example, are known for their distinctive coloration. Researching the specific habitat, diet, and breeding habits of your chosen species will help ensure a successful and enjoyable breeding experience.
Buying Isopods for Breeding
Starting or expanding your isopod colony often begins with buying isopods from a reputable source. Whether you choose to buy isopods from a pet store, online breeder, or at a reptile show, it’s important to select healthy individuals and to ask about their care and breeding history. Understanding the needs of the specific species you’re interested in will help you provide the best environment for breeding. Pairing male isopods, such as those from the Armadillidium vulgare species, with healthy female isopods can result in a new generation of young isopods to grow your colony. With careful selection and proper care, buying isopods is a great way to kickstart a successful breeding program and enjoy the fascinating process of raising these remarkable invertebrates.
