Seasonal abundance and diversity indices of spider’s web in the year 2013 to 2016 with special references of web pattern and architecture from different habitats of Eastern Region of Rajasthan, India

Abstract :

Spiders attract special attention to the zoologist on account of their unique weaving capability of constructing webs with geometrical precision. Web weaving habit of spiders are unique because few of others insects like (silk worm) produce silk, yet the survival value of silk spinning or web weaving has never been discovered by any observers. According to their web building ability, generally the spiders are considered as weavers or non-weavers Present paper describes the web architecture and patterns of spiders with respect to their diversity and distribution in the habitat of Eastern Rajasthan. There are more than 30,000 documented species of spider in the world. These species can be broken in to two categories: web builders and ground dwellers. The type of web spider spins depends entirely on the spider’s way of life. The pattern and architecture of webs varies family to family. During the study 6 types of web patterns Viz. Irregular web, Sheet webs, Funnel web, Orb web, Single-line web, Dome shaped horizontal webs were identified and analyzed between July 2012 to June 2015. These webs are thought to produce patterns that resemble patterns reflected by many flowers in U.V. light. Thus insect who are searching for their favorite type of flower see the decorated web in U.V. light and fly in to the trap. Spider web can take a variety of forms, but the most common type is the Orb web. The gradations of the web patterns can be written in the following order: Orb web > Sheet web > Irregular web > Funnel web > Single line snare web > Horizontal dome shape web. The orb web and Sheet web were very commonly observed during this study. The study focused on the spider’s web behavior and their survival strategy, which will help in their conservation
