Diversity and Seasonal Variation in Spider Abundance from MirajTahsil, Sangli, Maharashtra

Arachnida is one of the largest and important order from class Insecta. Arachnids are found over terrestrial ecosystem, however some inhabit freshwater environments and marine environments also. They comprise over 100,000 of species, including spiders, scorpions, harvestmen, ticks, mites and solifuges.
