ABSTRACT KEYWORDS

The study describes the identification of the spiders assemblage with respect to their diversity and Araneae , distribution among different places. Over all 35 mature male and female spiders were collected, belonging to 13 families, and 21 . It has been observed that abundance of spiders was high in spiders , garden while least recorded from road side vegetation. Male female ratio was found to be 20:15. The diversity, Wadali Lake and Vidarbha Campus is very dense forest area. These areas were surveyed during July conservation 2012- April 2013 for spiders’ diversity. . Over all 35 mature male and female spiders were collected, belonging to 13 families and 21 species. Of these collected spiders the most dominant family was Araneidae with 10 species of spiders.

INTRODUCTION Spiders are commonly named according to web pattern, behavior of spiders and resemblance with other .

Some of the common names are given in table 1. The order Arnaeae is large group of , which is commonly known as spiders. Spiders are web producing Table 1: Spiders Family name & common name. and eight legged .They are widespread and are found in all types of habitat and occupy all but a few niches. Sr. Family Name Common Name Spiders are worldwide distributed except Antarctica, sea No. and air. Spiders can be easily found in a small area, 1 Araneidae Orb web Spiders are of different sizes, colours with different 2 Clubionidae Sac / leaf rolling spider habitat .The and periods provide a 3 Eresidae large number of fossil spiders, including of many modern 5 Lycosidae Wolf spider families. The evolution of spiders has been going on for at 6 Oxyopidae Lynx spider least 400 million years, since the first true spiders thin- waisted evolved from crab-like 7 Philodromidae Elongated crab spider ancestors. Today, there are 42,473 described spider 8 Pholcidae Daddy-long-leg spider species within the diverse phylum of 9 Salticidae (Platnick, 2011). The spiders inject venom in prey to kill 10 Tetragnathidae Long jawed orb web weavers or paralyze it.

Kingdom – Animalia The attempt has been made through this project Phylum – Arthopoda work to record the fauna of spiders in Wadali Lake, Subphylum – Amravati, Vidarbha. The spiders are the bio indicators, Class - Archanida indicating the richness of . As spiders are Order - Araneae insectivorous, helps to keep the population of insect under control, therefore can be used as natural insecticide in agro ecosystem. © 2013|IRJSE.

MATERIALS AND METHODS Table 3: Spiders fauna from Wadali Lake, Amravati

Spiders were collected (every weekend) from Family I Aranedae vegetation, on ground, under stones/crevices, near lake sp. male etc. For collection of Spiders insects nets, pitfall trap Araneus marmoreus female female visual searching, beating, sweeping, and stroking sticks aemula male were used, the specimens were preserved in 70% alcohol, Cyclosa hexatuberculata Male labelled and identified according to Barrion and Litsinger (1995), Biswas and Biswas (1992), Davies and Zabka Leucage fastigata Male (1989), Gajbe (1987), Tikader (1962, 1970 ,1987) Neoscona sp Male Plantnick (1989, 2004). Neoscona sp Female Neoscona dyali Female Observations Zelotes choubai Male The Wadali Lake Vidarbha Campus is a area Zygiella sp. Female consisting of lake as well as rich flora and fauna. The Family II clubinoidae Vidarbha area is rich in flora and fauna. These areas Clubiona sp. Male comprises big garden also. The survey was done on every weekend so as to collect data of spiders in these Family III Erasidae particular areas. Spiders were collected from ground, tree Stegodyphus raipurensis Male trunks, vegetation, and grasslands under stones and near Family IV Hersiliidae water body. Emphasis was given on collection of mature savignyi Male/Female male and female spiders leaving immature to their Family V Lycocidae habitat. Repetition of collection was also avoided. Lycosa sp. Male/Female Over all 35 mature male and female spiders were Hippasa sp. Male collected, belonging to 13 families, and 21 species. It has Family VI Oxyopidae been observed that abundance of spiders was high in garden while least recorded from road side vegetation. Oxyopus chittrae Female Male female ratio was found to be 20:15.
