Light Blue Duns

Anglers used to know these mayflies by the revered name of Baetis vagans. Baetis tricaudatus was a Western species of relative obscurity, but entomologists recently discovered that it's the same species as the popular Eastern vagans. The scientific conventions guiding entomologists do not account for a name's fame among fishermen, and new or obscure species names sometimes replace our old favorites. Baetis vagans is one such casualty.

Fortunately, brown trout think like Shakespeare: A rose by any other name would smell as sweet. The rose that was vagans has lost none of its charm.
