| A monthly quantitative study on B. platycnemis (Fieber, 1851) was carried out in a sand dune marsh, on the littoral of Rio Janeiro State. The aims of this study were to correlate the life cycle of the species with the seasonal regime of the water body, defining steps of the annual cycle, age strueture, and to indicate oviposition sites and trophic relations. The species shows a marked seasonal tendency. The major steps of the life cycle obtained were an invernal (weak) with a predominance of imagines, followed by another of population expansion, characterized by the absence of adults, massive eclosions and predominance of low instar nymphs. Probably, B. platycnemis has a sensibility to water levei variation and might be intluenced by the concentration of... |
