Pillbug Lab Report

Pillbugs are also known as terrestrial isopods but non scientific names include sow bugs and woodlice. These terrestrial isopods are in the class of crustaceous, this class includes lobsters and crabs and is part of a larger group named arthropoda. Pillbugs have four pairs of mouthparts, and have multiple flexible joints. Pillbugs also have a flat and rounded back, wide head, 14 legs with 7 pairs all together, and they have the ability to roll into a ball when in danger. Pillbugs have 7 main “trunks”and have multiple overlain gills which allow the insect breathe. The diet of a pillbug consists of dead or decaying plant or animals, and pillbugs are both scavengers and omnivores. Due to their gills pillbugs live in areas with high humidity such as under fallen trees, logs, rocks, bushes, and wet leaves. In our hypothesis we state that if the pillbugs are accustomed to breathing water, then they will be drawn to the less sweet liquids. While completing this lab we used four liquids. We used water, milk, orange juice, and soda. To hold the liquids we used two q-tips. We used two petri dishes, one was to hold the pill bugs while they were not being used in the

Pillbug 2 was 56mm away from the water.50 mm away from the milk, 75mm awaY from the orange juice, and 3mm away from the soda. Trail three, bug one was 0mm away from the water, 55mm from the milk, 46mm away from the orange juice, and 80mm away from the soda. Trail three, bug two was 33mm away from the water, 75mm away from the milk, 25mm away from the orange juice, and 73mm away from the soda. Trial five, bug one, was 76mm away from the water, 51mm away from the milk, 65mm away from the orange juice, and 10mm away from the soda. For trial five, bug two, 75mm away from the water, 53mm away from the milk, 62mm away from the orange juice, and 7 mm away from the
