Burnished Brasses

Two Burnished Brass in the trap this morning. Usefully, one of each form. I picture them below in plan view and side elevation. (I have an engineering background)

  1. From one engineer to another, I like your presentation and attention to detail. From a mothing point of view there are people who think that these two forms are really separate species so may be a good idea to keep a record of the different forms when you get them.

  2. Colin Plant is working on it. If I'm correct, the 2 burnished areas have to be not only joined, but joined with a thick cross part to be a candidate for the second species. So I record in comment something along the lines of "No H", or thin "H" or thick "H". Last time I spoke to Colin about it, he was convinced of two species. To make things harder, the respective genitalia are just about identical.

  3. Peter, i will follow your example. Would you call mine a thin H or thick H please?
    I thought these sort of things were all sorted out by DNA these days, and splitters and lumpers were a thing of the past.
    When I am consorting with the opposition, I use DNA testing to sort out Whiskered and Brandt's bats from droppings. Now Alcathoe's bats have been thrown into the mix.to further complicate things.

  4. To be thick it has to be 3mm+. I'll e-mail you Colin's paper off group. If anyone else would like it, let me know.
