Male Enallagma traviatum
I was excited when I showed up at the Southwest Nature Preserve Bioblitz and @galacticbirder had already caught a damselfly.
When I looked at it I was kind of taken aback as the species Zach captured had only been recorded twice at one other location in Tarrant County (I only know this because I submitted those records).
Very good find and fortuitous start to the day. I saw at least two males (unsure if one was the one we released) of this species but no females during the bioblitz.
