'''''Graphium doson''''', the '''common jay''',<ref name=Smetacek/><ref name=funet/> is a black, tropical papilionid (swallowtail) butterfly with pale blue semi-transparent central wing bands that are formed by large spots. There is a marginal series of smaller spots. The underside of wings is brown with markings similar to upperside but whitish in colour. The sexes look alike. The species was first described by father and son entomologists Cajetan and Rudolf Felder.<ref name="bingham">{{Source-attribution|sentence=yes|{{cite book |last1=Bingham |first1=C.T. |author-link=Charles Thomas Bingham |title=The Fauna of British India, Including Ceylon and Burma |url=https://archive.org/stream/butterflies02bingiala#page/106/mode/2up/ |volume=II |edition=1st |publisher= Taylor and Francis, Ltd. |location=London |year=1907|pages=106–107}}}}</ref><ref name=MooreIndica>{{Cite book|url=https://www.biodiversitylibrary.org/item/103503#page/13/mode/1up|title=Lepidoptera Indica.

==Habitat== It is common in thick, riparian, moist, deciduous, semi-evergreen and evergreen forests.
==Behaviour== The common jay is active throughout the day and constantly on the move; it rarely settles down. Its flight is swift and straight. When feeding from flowers, it never settles down and keeps its wings vibrating. The males are seen mud-puddling, often in tight groups.
==Life cycle==
===Eggs=== The spherical and pale yellow eggs are laid singly on the underside of leaves.<ref name="bingham"/>
===Larva=== The caterpillar is somewhat spindle shaped. The grown caterpillars have two forms, dark brown or grassy green. There are spines on the fourth segment which are short, conical and blue centred surrounded by lemon yellow and then black rings. The osmeterium is pale bluish green. It is extruded only reluctantly.<ref name="bingham"/>
===Pupa=== The pupa is pale green with a dark purplish median line from the head to the thoracic horn and a yellow line from the tip of the horn to the cremaster.<ref name="bingham"/>

==Food plants== The caterpillars feed on plants of the families Annonaceae, Lauraceae and Magnoliaceae such as ''Annona lawii'', ''Annona muricata'', ''Cinnamomum macrocarpum'', ''Cinnamomum malabatrum'', ''Magnolia grandiflora'', ''Magnolia liliifera'', ''Magnolia oblonga'', ''Hunteria zeylanica'', ''Michelia champaca'', ''Trachelospermum asiaticum'' and ''Polyalthia longifolia''.
