Vulgare "sunset" is a variation of the orange gene in vulgare; it was separated later, although separately, from the "orange vigor" variety. Both mutations were founded in the US. In comparision, "sunset" vulgare isopods are a bit deeper of a red, don't produce as much oranges and the yellow speckling on their back appears to stand out more.
Vulgare do well in temperate and semi-arid environments. They are not recommended for tropical due to issues molting in high humidity. They enjoy eating many soft bodied plants.
