Oniscus Asellus, also known as “Common Woodlouse”, is an isopod that is large (one of the largest) in the British Aisles.  They can also be found throughout Europe and in the United States.  Our stock comes from New Jersey.  I found them back in 2016 under a slab of bark.  They are easy to raise and breed readily if kept cool (basement temp) and well fed.  If you are looking to purchase Oniscus Asellus, check out our healthy supply.
