Spider activity occurred in four ornamental plants was assessed for a whole year using pitfall traps for ground spiders and sweeping net for vegetation or aerial spiders.

A total of 456 individuals of ground and aerial spiders were collected.

By using shannon wiener and simpson indices, results revealed that species diversity were high under Plumbago shrubs for ground spider while the highest diversity of aerial spiders was recorded on red acalypha shrubs.

Monthly fluctuation of the total number of spiders should high population between May to August for ground spiders and in August to September for aerial spiders.
