The nominate subspecies ''P. c. calamorum'' is known from central and eastern [[China]], [[Korea]] and [[Japan]]. The subspecies ''P. c. dyeri'' occurs in southern [[China]], [[Hong Kong]], [[Taiwan]], [[Indonesia]], [[India]], [[Nepal]], and [[Thailand]].<ref name=iucn/><ref name=atlas>{{cite book |last1=K.A. |first1=Subramanian |last2=K.G. |first2=Emiliyamma |last3=R. |first3=Babu |last4=C. |first4=Radhakrishnan |last5=S.S. |first5=Talmale |title=Atlas of Odonata (Insecta) of the Western Ghats, India |date=2018 |publisher=Zoological Survey of India |isbn=9788181714954|pages=167–168}}</ref>

==Description and habitat==
It is a medium-sized damselfly with brown-capped yellowish green eyes. Its thorax is black on dorsum without any or very fine azure blue antehumeral stripes, which are very broad in ''[[Paracercion malayanum]]''. Lateral sides of thorax are greenish blue with a fine black line on the upper part of each lateral suture. In old males, all these marks are obscured by bluish white [[pruinescence]]. Its wings are transparent and [[pterostigma]] is yellow, framed with heavy black nervures. Its abdomen is azure blue with broad black dorsal marks up to segment 7. Segment 2 has a distinct broad dorsal spot connected narrowly to a fine apical ring. This mark will help to distinguish it from ''[[Pseudagrion]]'' species. Segment 10 has a narrow mid-dorsal black streak. Female is dull in colors. Its abdomen is similar to the male. But the lateral ground colour is greenish-yellow and segments 8 and 9 are broadly black on dorsum. Segment 10 is bluish-green. Female also get pruinosed when aged.<ref name="Fraser-RIM">{{cite journal |last1=Fraser |first1=F.

It breeds in stagnant and weedy ponds, resting flat on floating grasses and lotus leaves. Eggs are inserted well within the up-curled rim of the lotus leaf or any other floating vegetation.<ref name=Fraser>{{cite book|author=C FC Lt.
