Isopods are classified under order peracarid crustaceans. Since isopods are crustaceans, they breathe through gill-like structures; however, isopods cannot survive underwater. Instead, they live on land in a damp habitat. In order to sustain that damp environment, they prefer dark surroundings. Because of their requirements, isopods are commonly found under rocks and other light-blocking objects. Furthermore, it also explains why they are most active during nighttime and why they are more visible when it rains.
If a pill bug happens to venture out into a bright and dry environment, like a building, they will most likely dry out and die. Isopods are decomposers, so their main sources of food are decaying wood and other plants. Other possible sources of food are decaying animals, scat, and live plants. This makes them a possible pest for growing foods, such as strawberries and potatoes, in the garden. When having isopods as pets, easy types of food to feed them can include dead leaves and rotting wood.
There are thousands of isopod species, one of them being woodlice. Moreover, Armadillidium vulgare is a species of woodlouse. It is known by multiple other names, such as “roly polies,” “pill bugs,” and “potato bugs. ” Pill bugs are native to Europe. They are oval-shaped with a dark colored shell, and they defend themselves by rolling into a ball. They either prefer a bright or dark environment depending on the temperature. The hotter the surrounding temperature is, the darker the environment that they prefer.
