Young Southern Spreadwing Male - Lestes australis
Harris County, Texas, USA
March 18, 2012
Is this a Southern Spreadwing?
With no blue in the face, brown eyes, tan antehumeral stripe, and a minimally pruinose S9, I believe this is a young male.
Edited on 2/4/2015 by removing what followed and replacing it with the following:
I believe the answer to my question is "Yes!".
Please note the following observations regarding this individual are OK for Southern:
Back of head is uniformly coppery.
Mid-dorsal stripe is moderately wide.
Antehumeral stripe is relatively narrow.
Mid-dorsal/antehumeral border is irregular.
Legs are generally dark.
Lower side of thorax is whitish.
Dark ventro-lateral spots at rear of S3-S6.
Paraprocts are longish with a bit of curve.
Using Abbott’s “Damselflies of Texas” eliminates those spreadwings whose range lies “far” from our area. That leaves only Plateau, Elegant, Rainpool, and Swamp in addition to Southern.
Using the same source:
It is not Plateau because Plateau has short, straight paraprocts; is lacking or has weak ventro-lateral spots; and has a straight mid-dorsal/antehumeral border.
It is not Elegant because Elegant has paraprocts that are longer than its cerci; lacks ventro-lateral spots; has a narrow mid-dorsal; and the back of its head is pale.
It is not Rainpool because Rainpool has a narrow mid-dorsal flanked by a metallic green stripe that is “always present” above the antehumeral, and its legs are generally pale with a dark stripe “on femora and front of tibia”.
It is not Swamp because Swamp has a narrow mid-dorsal stripe.
As far as I can tell, this individual conforms to all the requirements for a young Southern Spreadwing male without violating any. I am no expert, nor did I research this thoroughly. Please let me know if you notice a significant error. I will modify this farther as necessary.
