Abstract

The larva of Somatochlora filosa (Hagen) is described from 3 males reared from the egg to the final instar. One male transformed to the adult 669 days after the egg was laid. S. filosa last instars have 9 palpal setae whereas all other described North American Somatochlora larvae with dorsal abdominal hooks have 8 or less palpal setae. The larva of S. filosa resembles that of S. provocans Calvert most closely but has a less acuminate epiproct and more numerous and longer hairs, especially on the vertex and tibiae. S. provocans has well developed ventral triangular sclerites at the antero-lateral corners of abdominal segments 3 and 7; in S. filosa these are absent or obscure.
