Yes, most of our lakes have good populations of damselflies but the fly shown was tied as a Callibaetis imitation and has proven to be particularly effective in the half-hour or so prior to the hatch of Callibaetis duns when the nymphs are making their way to the surface. I do tie a damselfly nymph, based on a pattern developed by my friend Dale Dennis. I also tie and fish patterns imitating damselfly tenerals and adults. The teneral is a just-emerged adult which has not yet achieved its mature adult form and color. They are poor fliers and are often blown or knocked off of their perches to fall on the water and can sometimes be more effective than imitations of the fully-mature adult. My version of Dale's damselfly nymph utilizes a thin strip of squirrel Zonker strip for its abdomen.
