Identificaciones de tiffatiel

I saw two males and one suspected female. There were more last month. Not sure if I saw fewer this time because of the weather (it was cold and foggy; last month I was there on a sunny day), because of being at a different stage in their life cycle, because of there being less water in their habitat, because of habitat disturbance (some of the grasses and rushes had been trampled down and there were spots of glitter around - looked like there had been a party maybe), or some other possible reason.
