St. Lucia Isopods, also sometimes referred to as "Jelly Bean" isopods in the hobby are a must have if a display isopod is high on your list. It's easy to see where the common name jelly bean came from. This version of Armadillidium Vulgare has an assortment of bright vivid colors including various hues of orange, yellow, gold, light pinks and deep red along with some wild type colors ranging from gray to almost black. Even better, this genetic morph also has other variations within those colors such as defined segmented stripes, dalmatian patterns and some with infused gold metallic splotching. It should be noted all of these colors and characteristics can and do vary with each and every individual. Intensity and frequency of colors and patterns are all over the chart. The offspring will also come out the same variety of colors regardless of the coloration of the parents.
Armadillidium Vulgare is a very common isopod species and the one most people are referring to when the iconic term "pill bug" or "roly poly". They are native to Europe, most notably in the Mediterranean basin area but have established themselves nearly worldwide. They are a beginner friendly species being fairly flexible in their needs and tolerant of a variety of environmental conditions. Armadillidium Vulgare 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 of these beauties. 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 around the mid 70sF will suit them just fine. A. Vulgare prefers a temperate climate with good ventilation. 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. While this isopod is also a great bio custodian, it should be noted they have a reputation for munching on live plants as well. We can attest to this after trying several times to have various small plants in the enclosure with all being completely consumed in a few days or less.
Armadillidium Vulgare "Saint Lucia" is an easy species to keep and is fairly forgiving with the learning curves of new keepers or the occasional memory lapse. Their visually appealing variety of colors combined with the fact they are modestly day active instead of hiding the bulk majority of the time means this is an isopod you can actually enjoy and appreciate all hours of the day or night.
