AbstractA chironomid population found in a temporary pond in South Dakota and believed to be conspecific with the European Chironomus pallidivittatuswas studied. Field and laboratory observations of intraspecific mating behavior are reported. The percentages of females producing viable eggs in crosses of C. pallidivittatusmales with females of C. tentonsand C. crassicaudatuswere 6.2% and 6.3% respectively. In the reciprocal combinations, mating was difficult to induce and no viable eggs were produced. Neither the South Dakota population nor the European species called C. pallidivittatusconform to the morphology of the lectotype. |
