The Details:
Vulgare morph displays a range of bright oranges.
Vulgare is a surface isopod that thrives in temperate environments with a moderate moisture gradient. Keep one side moist to maintain humidity. Armadillidium does not tolerate excessive moisture. Good ventilation is essential.
 
Not sexually dimorphic.
 
AKA "Pill Bug," thus rolls into a ball ("arma") to retain moisture when the habitat is too dry, as well as a defensive posture.
 
NOTE: Color morphs are a product of unnatural selection and captive stock that produces numerous variations in the standard color pattern. In the case of Armadillidium vulgare, the wild/original color is dark grey.
