Black Betty

Shall be her name today, until someone can help me out on the ID! I've searched numerous websites and looked at hundreds of images and still can't find anything that comes very close...

She has two separate sets of wings and the second pair which she keeps hidden when resting have a white patch on each side. Her body is also a brilliant red colour and what is very cool are her neon blue antennae which you can see in this image. I particularly like the textured pattern on her upper wings.

I flushed her a couple of times to try and get a good look at the hidden wings and hoped she would land with them open but it seems that this probably how they hold them normally when at rest, and she was not in any hurry to head out feeding!
