The name Blue Winged Olive (BWO) is a common name given to several species in the Baetidae family. BWO mayflies are named for the dun stage as it has an olive body and opaque blue-gray coloured wings. As BWOs are small, most anglers avoid imitating the nymphs and focus on the adults using dry flies tied on 16 and 18 hooks.
