Analysis of Sow Bug Behavior in Selective Environments Abstract The purpose of this lab was to observe the behavior of sow bugs in different environments when given a choice of two different environments to be in. The observations were conducted through two different experiments. In the first experiment we observed the sow bugs preference of environment between a dirt environment and a sand environment. This was done by placing the sow bugs in an environment that featured isolated areas of sand and dirt in equally divided sections and recording what section they were positioned in every minute for 5 minutes. It was observed that the sow bugs spent more time in dirt environment than in the sand environment because the sow bugs had more recorded positions in the dirt environment. In the second experiment we observed the sow bugs behavior in an environment that contained two different levels of illumination. This was observed by placing the sow bugs in an environment that equally shared two sections each having a different level of illumination and recording the environmental position of the sow bugs in 1 minute intervals for five minutes. In general the position of the sow bugs was more often in the environment that had the higher level of illumination. It can be concluded from the observations and records of the 1st experiment that sow bugs prefer to spend more time in and environment that consist of dirt rather than one that consist of sand. From the observations and records of the 2nd experiment it can be concluded that sow bugs prefer an environment with higher levels of illumination rather than one with a lower level of illumination. Introduction Sow bugs also known as woodlice or pill bugs are small round topped insects with 7 pairs of legs. Sow bugs belong to the Class Crustacea other crustaceans include lobsters, crabs, and shrimp. Dr. Jonathan Wright of
