The quest for understanding how organisms interact with their environment has always been a cornerstone of ecological studies. Among the myriad of creatures studied for such interactions, pill bugs offer a fascinating glimpse into preference-based habitat selection. Known scientifically as Armadillidium vulgare, these small, terrestrial crustaceans are commonly found in moist environments, such as gardens or beneath house foundations. Typically measuring around ¾ inch in length, pill bugs have a lifespan of up to two years and primarily feed on vegetables.
Notably, they are distinguished by their harmless nature, as they do not transmit diseases. This study aims to explore whether pill bugs exhibit a preference for wet or dry environments, thereby contributing to our understanding of their habitat selection behaviors.
The central hypothesis of this investigation posits that when presented with a choice between a moist and a dry environment, pill bugs will demonstrate a preference for the wet environment. This hypothesis is rooted in the natural history of pill bugs, which suggests a predilection for moist conditions to maintain their hydration levels and perhaps, more broadly, their survival and reproductive success.
To test this hypothesis, an experimental setup was devised using two petri dish halves, one moistened and the other left dry, connected by an opening to allow free movement between the two environments.

Ten pill bugs were introduced into this setup, with an equal number initially placed in each dish. The experiment was designed to observe the movement of these pill bugs over a nine-minute period, allowing them to choose between the wet and dry environments.
The distribution of pill bugs between the two environments was recorded at regular intervals to assess their preference.
The observational data collected during the experiment revealed a dynamic preference pattern among the pill bugs. Initially, all ten pill bugs congregated in the wet environment, indicating a strong initial preference for moisture. However, this preference was not absolute, as evidenced by the migration of one pill bug to the dry environment at the 4:30-minute mark, followed by two more at six minutes. Despite these movements, by the conclusion of the nine-minute observation period, all pill bugs had returned to the wet environment, underscoring their overall preference for moist conditions.
The findings of this study strongly support the hypothesis that pill bugs prefer wet over dry environments. This preference was demonstrated by the unanimous return of all pill bugs to the wet chamber by the end of the experimental period. The temporary migration of a few pill bugs to the dry environment suggests a complexity in their habitat preference that warrants further investigation. The experiment's outcome not only sheds light on the adaptive behaviors of pill bugs, enabling them to seek out environments conducive to their survival and well-being but also highlights the importance of considering environmental preferences in the study of organism behavior.
Potential limitations of this study include the artificial nature of the experimental setup and the limited observation period, which may not fully capture the range of behaviors pill bugs exhibit in more natural settings. Future research could extend the observation period, vary the environmental conditions, or explore the preferences of pill bugs for other environmental factors, such as light or soil type.
