The species was described by Needham in 1930 from Sichuan. It has been recorded from a few scattered high-mountain locations in southern China. Wilson synonymised S. dido with S. taiwana from Taiwan, after finding that specimens from Guangxi were intermediate in the structure of the appendages. It is interesting to note that specimens from Taiwan seem to miss to first lateral stripe, which is so prominent in S. dido. Be that as it may, S. dido was recorded in 1995 by Asahina from the same general location as where Sebastien found it again in 2012 and 2013. To this we can now add my own 2015 records. So far the only site known from Vietnam, although it may be occurring in the forest around Fansipan. There are various bogs in there, although difficult to access because entry is restricted.
|Somatochlora dido, male. Note the diffuse orange-yellow postclypeus and bright yellow labium, and the two yellow lateral stripes.|
|This species hovers about 1-1.50 m high over trickles in acidic swamp areas and flies amongst tree tops when hunting|
