A review of factors threatening the continued survival of Jamaican Giant Swallowtail or Homerus Swallowtail, Pterourus (Pyrrhosticta) homerus (Fabricius, 1793), with recommendations for mitigating threats

Abstract

This paper documents the major threats to each of the two remaining subpopulations of Homerus Swallowtail Pterourus (Pyrrhosticta) homerus (Fabricius, 1793), evaluates the insect’s present conservation status, examines the limitations of current conservation measures, and documents the need to implement additional protections. Evaluations presented here of deteriorating habitat conditions of this endemic swallowtail and its small population size lead to the conclusion that the IUCN conservation status of the Homerus Swallowtail should be upgraded from Endangered to Critically Endangered.
