Exam TwoQuestion OneQuestion TwoThe red-backed jumping spider (Phidippius Johnsoni) is found in western North America and was introduced to New Zealand with contaminated imported table grapes. They undergo a gradual metamorphosis. They spin tubular nests from silky threads under fallen logs, rocks, and other debris on the ground. They hunt by sight, so they are diurnal and mostly stay in their nests at night. Their nests also provide shelters in which molting, laying and hatching can take place, and provide protection from the elements. Sometimes courtship and mating take place inside these nests. Male spiders exhibit distinctly different courtship methods, one when courtship occurs when the male encounters a mature female inside his nest, another when a male encounters a female who is not fully mature, and another if the male meets a mature female. outside the nest. The male Johnsoni does not attempt to court immature females when encountered outside the nest. Outside the nest, males engage in visual courtship as these spiders have adapted to have more sophisticated vision. When males come into contact with a mature female inside the nest, he courts her using vibrations because they do not see as well in the dark. If the male meets a female who has not yet reached full maturity, he will court her using the vibrational method and if she accepts him, he will cohabit with the female until she matures and is ready to s 'couple. Once eggs are fertilized, females lay eggs in consecutive batches beginning about a month after fertilization, with one month passing between each next batch of eggs laid. The eggs hatch about three weeks after being released and the young spiders leave the nest in the middle of a sheet of paper......http://www.americanarachnology.org/JoA_free/JoA_v6_n1/JoA_v6_p1.pdfhttp:/ /www.aaie.net/aaie/node/85http://www.jstor.org.libproxy.sbcc.edu:2048/stable/3705218?&Search=yes&term=nest-mediated&list=hide&searchUri=%2Faction%2FdoBasicSearch%3FQuery % 3Dnest-mediated%26x%3D0%26y%3D0%26wc%3Don&item=1&ttl=6&returnArticleService=showArticlehttp://www.americanarachnology.org/JoA_free/JoA_v8_n3/JoA_v8_p241.pdfhttp://www.jstor.org.libproxy.sbcc. edu:2048/stable/3704985?seq=2&Search=yes&term=johnsoni&term=phidippus&list=hide&searchUri=%2Faction%2FdoBasicSearch%3FQuery%3Dphidippus%2Bjohnsoni%26gw%3Djtx%26prq%3Dpidippus%2Bjohnsoni%26Search%3DSearch% 26 ch%3D25% 26wc%3Don&item=6&ttl=132&returnArticleService=showArticle&resultsServiceName=doBasicResultsFromArticlehttp://www.naturegrid.org.uk/biodiversity/invert/glossary.htmlhttp://bi154.dhcp.ttu.edu/sean/shell.pdf
