Larvae of Paraboreochlus stahli were collected from two streams, Esopus Creek and Coxing Kill, during a study of hyporheic invertebrates in the Lower Hudson River Basin in southeastern New York. All were collected from hyporheic zones of exposed lateral gravel bars using the Karaman-Chappuis method. Only two larvae of P. stahli were collected in October from Esopus Creek. By contrast, larvae were present through most of the year at Coxing Kill, but were more abundant in fall and spring samples, and consisted of a mixture of second, third and mature fourth instars. It is concluded that larvae inhabit and grow to maturity in lateral hyporheic zones, which may account for their absence in standard benthic samples from streams.
