Armadillidiidae is a family of woodlice‚ a terrestrial crustacean group in the order Isopoda. Unlike members of other woodlouse families‚ members of this family can roll into a ball‚ ability they share with the outwardly similar but unrelated pill millipedes and other animals. It is this ability which gives woodlice in this family their common name of pill bugs‚[1] doodle bugs‚ or roly polies. The best-known species in the family is Armadillidium vulgare‚ the common pill bug. The Classification

are cold-blooded‚ which means their body temperature is regulated by the surrounding environment (Grzimek). Like other invertebrates‚ pillbugs are ectothermic‚ meaning their body temperature varies with the environment (Pillbug Profile). Since Armadillidiidae vulgare (Isopods) rely so much in their environment‚ we decided to come up with an experiment to show what kind of environment these specific Isopods prefer. After the set up‚ Isopods were observed in 5‚ 10 15 minute intervals. This will give

ABSTRACT Pill bugs live in an outside environment where they are able to get the necessary amount of energy from organic matter. This environment is where water and organic matter is plentiful. In there natural habitat‚ pill bugs are found in dark‚ damp places. Living in moist places is important for pill bugs so they can take in enough water‚ and if water is not available‚ they group together to prevent water loss. Pill bugs most often live in dark places because they have a negative photo taxis

The Rolling Choice A pillbug also known as a roly-poly is a small land creature that is often found in many areas around the world. They prefer moist areas often living in soil‚ under rocks‚ and dead logs. The pillbug which is an isopod begins its life as a tiny egg and as it grows it sheds its old exoskeleton 4 to 5 times. A pillbug consists of three basic body parts‚ the head‚ thorax‚ and the abdomen. Pillbugs eat decaying plants and animals as well as some living plants. The purpose of this

For the first part of the experiment we found that four of the five pill bugs found their way to the leafy environment. However‚ most of their time was spent in the section of soil. For the second part of the experiment where we tested each of the pill bugs separately‚ we found that the bugs spent most or all of their time in the soil environment‚ therefore‚ composing the answer to the question of their most favored environment. The chart in image two contains the data found in the first part

Assessment The structural features of the pill bug allows it to have advantages over other organisms. The pillbugs multi-segmented body allows it to roll into a ball if it feels threatened or in danger in order to protect its self. Another advantage of have a multi-segmented body is it allows the pillbug to semi curl to flip its self back over if it is knocked down. The antennae is used to sense the environment around it‚ even if it is in ball shape form. The advantages of this is the pillbug

Food Preferences in the Sow Bug (Porcellio Laevis) Purpose The purpose of this experiment is to determine what kind of food the sow bug prefers; decaying leaves‚ potatoes‚ grapes‚ or sow bug food. Hypothesis If a sow bug is placed in a choice tray‚ and has access to decaying leaves‚ potatoes‚ grapes‚ and sow bug food‚ the sow bug will choose the decaying leaves over its other options. This hypothesis was based on research stating that a sow bug’s main food source is decaying vegetation. This

Abstract A two-part study was recently done to show what natural habitat a Pill bug‚ Armadillidium vulgare‚ naturally prefers: wet or dry environments along with a light or dark environment. It was hypothesized that a Pill bug would prefer and wet and dark environment based on its natural habitat of soil. For the wet and dry experiment‚ a coffee filter and soil were placed in each chamber of a double petri dish with one being dampened before being placed in. For the light and dry experiment a light

This lab felt very “slow” because there was not a lot of action going on. The pill bugs would either walk around in circles or stay put. However‚ it was both fun and annoying when my group tried to put the pill bugs in the chamber and take them out. We had to put a lot of effort to get the pill bugs on to the paint brushes because they would scurry around and it would take a while to find them. Also‚ it was cool to see the pill bugs use their defense mechanism (it only happened once) by going into

Pill Bugs Turn Alternation Lab Report Bio Lab 111 Nov. 15‚ 2012 Pill bugs are said to have some sort of turn alternation built in there cognitive functions‚ which causes them to take a zig-zag route rather than going along in a straight line for a long distance (Ono Tomohiro & Takagi Yuika‚ 2006). Distance does not play a factor in the pill bugs making turn alternation even if it is a forced turn‚ pill bugs will still make a zig-zag motion (Kupfermann‚ 1966). The zig-zag motion shows that
