American rubyspot on a long leaf. It is in the center of the photo, looking left, and surrounded by grass. This appears to be the female green form. The damselfly has a long, mostly deep green abdomen. Its head appears to have a green line between light-colored eyes and the thorax has a metallic green line in the middle between tan and brown markings. The wings are mostly clear with visible veining, except at the base where the wings are red. There is a tan line near the top of the wings and a thin black line at the top and a white tip near the end.

Y’all, meet the oldest #rubyspot I have ever known. He is Hetaerina titia male purple-yellow-orange-purple, and he is 100 days old. #rubyspots2024

Which reminds me, we’re back in the field with another #rubyspot field season well underway here on the Pacific coast. #rubyspots2022

Now out in early view in @BehavEcol, evidence that microhabitat divergence is another pathway to decreasing the frequency of interspecific territorial fights in #rubyspot damselflies. Led by @ShawnMceachin ft @c_n_anderson ...

The river went down & we successfully finished our grueling experiment. Now: homeward bound for data analyses! #REU #rubyspot #fieldwork

Sometimes #fieldwork = hell AND high water. (Our transect line is ~5m down there somewhere). #rubyspot #REU

After sampling at a bunch of sites, we've now settled in and put up our transect in W. Louisiana #rubyspot #fieldwork

Sad to leave our RV park goat friend, but on we go! #rubyspot #fieldwork

Tonight in Louisiana, tomorrow: damselflies #rubyspot #fieldwork

Made it to Tucson! Next stop:TX #rubyspot #fieldwork

We know smoky #rubyspot wing color varies seasonally, but we're off tomorrow to keep learning how they vary geographically. #REU #fieldwork

Planning the next leg of fieldwork--it's going to be a hot summer. #rubyspot #fieldwork
