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.

I have not observed lekking behavior in Adela purpurea; I'm interested to see that
term used for Lepidoptera. But I see this species occasionally, usually on Fleabane (Erigeron),
and was wondering while trying to take a photograph of one two days ago if the color
was strutural rather than pigment; as the wings look mostly black from most angles,
but quite purple from some angles. Here is a photo I took two days ago of one; it
took many tries to show this much purple.

I've read about structural colors in butterflies, but not moths, so I was curious.
Also, it would be interesting to know if there has been any speculation for the
unusual length of the antennae.
