Arachnology is an attractive field of spiders, but it is largely ignored due to dislike of spiders. The objective of this study was to update the list of spiders in various patches of Mangalore University campus. Different sites of the Mangalore University campus were studied for spider diversity. A total of 32 species belonging to 16 genera were documented during the study period. Of these, ten genera were found to be arboreal, grassland ecosystem has species belonging to three genera and six were found to be in human constructions. Of all the 16 genera observed Plexippus was found to be abundant. Oxyopes was found to be more in number in arboreal spiders. Biodiversity indices revealed that the species richness in arboreal and dominance of some species over others in human constructions.
