SFRC M-649 The Status of the Schaus Swallowtail and Bahama Swallowtail Butterflies in Biscayne National Park
Loftus WF and Kushlan JA. 1982. SFRC M-649 The Status of the Schaus Swallowtail and Bahama Swallowtail Butterflies in Biscayne National Park. Report M-649. South Florida Natural Resources Center. Homestead, Florida
Surveys of the Schaus swallowtail and Bahama swallowtail butterflies, both federally-listed threatened species, were undertaken during 1979 and 1980. The survey was continued by Biscayne National Park personnel during 1981. Transects were routinely monitored on several keys in Biscayne National Park to determine the numbers of adults present, to delineate the emergence season and distribution, and to identify factors which affect their status. The population size of the Schaus swallowtail on the keys was small during 1979 and 1980, but adults were widely distributed in suitable habitat. Emergence season was similar in both years, occuring from late April to late June. Numbers of the Schaus swallowtail were lower on the 1981 surveys, and the emergence period seemed to be retarded. The Bahama swallowtail was not observed during the surveys, and its existence in the Biscayne National Park is doubtful. Data on cohabitating lepidopterans was collected and is presented here.
