    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.
