Some methods to observe spiders
Spider webs are easily photographed against the light, or by lightly dusting with corn starch or talcum. To collect spiders, one can sweep vegetation with a butterfly net, or sift ground litter using a cylinder of cloth with a 5-mm (1/4-inch) wire screen on the bottom. A ground trap, an open tin can buried flush with the surface, will catch running spiders. Live spiders can be kept in a terrarium with a dish with water.
