Scarce swallowtail as far as the Arabian Peninsula, Pakistan, India and western China. A few specimens of the scarce swallowtail have been reported from central Sweden and the United Kingdom but they were probably only strays and not migrants. These swallowtail butterflies inhabit gardens, towns as well as the countryside, in fields and open woodlands. They are found in places with sloe thickets and particularly orchards. In the Alps they can be found up to altitudes of 2000 m., but usually they prefer foothills and lower levels.

Comma category difference between the two notions is that a natural transformation is a particular collection of morphisms of type of the form formula_182, while objects of the comma category contains "all" morphisms of type of such form. A functor to the comma category selects that particular collection of morphisms. This is described succinctly by an observation by Huq that a natural transformation formula_183, with formula_184, corresponds to a functor formula_185 which maps each object formula_8 to formula_187 and maps each morphism formula_188 to formula_16. This is a bijective correspondence between natural transformations formula_181 and functors formula_185 which are sections of both
