Information on Armadillidum vu
Armadillidum vulgare or commonly know as pill bugs or roly-polys are dark gray, ¼ inch long humpbacked, oval isopod crustaceans. They look like they are covered in a segmented armor. Pill bugs are often misstated for sow bugs. They can be distinguished from sow bugs because pill bugs are able to roll themselves up into a ball when alarmed, and they lack the two prominent tail-like appendages (http://www.arrowexterminating.com/insects2.html#PB). Roly polys are found in damp, humid, and cool conditions. They are easily found in the seasons of autumn and spring. They are easily found around home in compost sites, or under shelter such as rocks, bark n and boards left in shady, moist conditions. Also they might be found fairly deep in damp soil litter under the cover of trees or bushes. Hot summer temperatures cause roly-polys to dig deeper into their shelter, so they are harder to locate. Also the cold winter temperatures cause them to def deeper into shelter (http://www.seds.org/nineplanets/nineplanets/venus.html). Lots of the behavioral responses of roly-polys are mostly with conservation of water and the need to avoid desiccation. Lots of roly-polys are
This means that roly-polys move away from bright conditions into darker places. Roly polys show a positive thigmokinesis. These devices are put against moist surfaces, and capillary action causes water absorption. In dryer locations slower rates of velocity were recorded than in humid conditions. The water lost has to be replaced, to do this roly-polys take up water through their uropods. So they are less active when a lot of their body structure is touching other objects, even other roly-polys. They will move around so that the maximum amount of their bodies are touching other things. Roly polys have 7 pairs of legs, and their bodies to have 3 sections, but these are hard to be sure where each different section begins, or ends because they are often fused together.
