Leuctridae: Leuctra sibleyi - Leuctra sibleyi

Leuctridae: Leuctra sibleyi - Leuctra sibleyi
Mad River, 2 km W Farmington, Strafford County, New Hampshire, USA
April 20, 2008
I have yet to get a good photo of L. sibleyi, but you can see the distinct whorls of setae at the joints of the cerci. All the other species have these whorls shorter in length and not nearly so easy to see, or in the case of Tom Murray's photo of a Leuctra, the setal whorls are long but the segments of the cerci are very distinctly enlarged.
