Notes on the osmeteria of Papilio homerus larvae (Lepidoptera: Papilionidae).

E. Garraway, J. R. Parnell


All larval instars of Papilio homerus have well developed osmeteria. Close up photography of living larvae shows the osmeteria are light pink in the first three instars and brick red in the fourth and fifth instars. Notes on the reluctance of mature larvae to extrude the osmeteria and protective camouflage are included.
