Slaty Skimmers

local time : 4:16 pm
Cordova, Memphis

Slaty Skimmer (bluish) | male
i add here two photographs of adult Slaty Skimmers (Libellula incesta).
now the question is: gender!

interestingly.. what i have noticed.. the adult males of this species come in two different shades. more bluish and more purplish. don't know the reason, but adding the other one too.. for comparison.

 interesting is the fact that i found both the 'types' sitting on the same perch (as you can see in the photographs).. obviously, at the same place then.. but in a gap of more than one month! the first photograph was taken on 14th August, 2012.. and the second, on 6th July, 2012!

Slaty Skimmer (purplish) | male or female?
or could it be two different species? after all, Bar-winged Skimmers also look quite alike..
though, i still believe, both the subjects added here, are Slaty Skimmers (Libellula incesta) only.

this species, Slaty Skimmer, can be found in the eastern part of United States. the females have yellow-brown stripes. flight season: May to October.

some sources say, the purplish one is adult female. and the striped one, juvenile. which makes me more confused!

PS: both the photographs are taken using my Canon PowerShot SX40 HS. editing: CS5.
