For the past 5 years, I have been watching Adela purpurea here in Connecticut. I was surprised to see the males lekking above pussy willow as I had not read about that behavior. I’m wondering if anyone else has seen this. Also, does anyone actually have a female in their collection? I do not think I have seen one yet and all the specimens at UCONN were males.
Here is a video showing the lekking behavior (the last section is slowed down by 2x). UInfortunately, it only shows one male flying at a time. I have seen groups of over 20 and maybe 30, but typically 1 to 5.. There are some still photos of up to four males in the frame at the end.
I would enjoy comparing notes with anyone else who has been observing A. purpurea.
