Abstract
This paper represents a continued study of the emergence phenology of adult crane flies from a small stream in northeastern Puerto Rico. Twenty-two species were collected by an emergence trap from February 1991 through April 1992 at Quebrada Prieta, a second-order stream in the Luquillo Mountains. Four species of Limonia comprised 53% of the individuals and one species alone, Limonia (Geranomyia) virescens (Loew) comprised 22%. These additional fifteen months of emergence data confirm the pronounced seasonality in the crane fly emergence phenology reported by Gelhaus et al. (1993), with most emergence occurring during November through April, and little or no emergence from June through September. Decline in the individuals of the dominant species, L. virescens, and in numbers of total Tipulidae overall, may be related to the canopy re-growth following the destruction by Hurricane Hugo in 1989, and the resulting decline in light levels and benthic algal levels. Grazers on benthic algae included 48% of the crane fly individuals. Limonia (Discobola) gowdeyi Alexander and L. (Neolimonia) caribaea Alexander are recorded from Puerto Rico for the first time.
