Not to be confused with it's cousin Armadillidium Vulgare, this isopod does share the same genus but it's a separately classified species. It's scientific name "Nasatum" is actually derived from a rectangular protrusion on the head that resembles a nose. Hence one of the common names for this species "Nosy Isopod". This is one quick easy way to distinguish it from similar isopods. Taxonomy aside, A. Nasatum is just as easy if not easier to care for as A. Vulgare. Nastaum isopods on average can grow up to around .80 inch in length and have a slightly elongated build. You can likely find the common version in earth tone colors in your own back yard, but this version called "Peach" is from years of selective breeding and they do not occur naturally in the wild. When they are tiny babies they have little to no color and tend to stay hidden or buried in the substrate. Juveniles and sub adults are brightly colored and mature adults have a slightly deeper hue.
Armadillidium Nasatum is a common isopod species and the one most people are referring to when the iconic term "pill bug" or "roly poly" as they can roll up into a nearly perfect ball. But Nasatum falls short of a perfect sphere which is another distinguishing difference from other comparable species. They are native to Europe, but have established themselves nearly worldwide with the help of humans and agriculture. They are a beginner friendly species and can thrive in nearly all environmental conditions ranging from semi arid to sub tropical. This makes this isopod one of the few that can can serve as a valuable clean up crew for other animals that like it more on the dry side. As always, they still need some moisture and will quickly desiccate in a zero humidity environment. It should be noted that the newborns do require a bit higher humidity and are more sensitive to drying out during this stage of their life cycle. Armadillidium Nastum is a relatively outgoing isopod that can be seen exploring and moving about their enclosure at various times. As with most isopods, higher numbers means higher visibility.
A 6 quart gasket sealed storage bin or small glass aquarium is sufficient for a small starter culture. Standard or bioactive enclosures can be enhanced with natural botanical items to simulate the isopods habitat in the wild. This helps them feel secure which in turn promotes their natural processes like eating and breeding. Average room temperature in the low to mid 70sF will suit them just fine. Around one third to half of the enclosure should have damp (not wet) sphagnum moss with the remainder being a bit on the dry side, but not completely devoid of some moisture. They will often migrate between moist and dry areas at different times of the day. A few pieces of cork bark strategically placed over some of the moist side will help retain the humidity levels and reduce the frequency of watering needed to maintain a proper moisture gradient.
Isopods are detritivores. Their primary diet in nature is leaf litter and decayed wood. Both of these should always be available in abundance. They will also happily consume any other decomposing organic plant or animal matter they come across. As such it is vital to supplement your isopods with other food sources on a semi regular basis. They enjoy food options like squash, radishes, carrots and other veggies along with commercial isopod powdered food like Repashy. They also need some occasional protein in their diets which can be things like freeze dried minnows, shrimp, fish pellets, dried insects and other protein based food sources. Be sure to feed these on the drier side as they can spoil quickly in humid environments and attract unwanted pests.
Armadillidium Nasatum "Peach" is a very easy species to keep and is forgiving with the learning curves of new keepers or the occasional memory lapse. The range of orange-pink tones in an established culture is aesthetically pleasing and you won't always have to hunt for them to enjoy this as they are both day and night active.
