Oh yes I did. The abstract was quite interesting, if you read closely the hypothesis was that the insect would be darker in cold climates to help the insects keep warm. The quot and the position in the abstract that tells me how much this hypothesis is worth is this one

Perhaps there is another explanation. In the current question as to whether this effect is great enough to make as big a difference as seen between Walters butterfly shot and mine, or whether processing or perhaps color space caused the difference, the abstract doesn't tell us that. In fact it tells little or nothing at all. AlunFoto wrote: > If you scroll down, the abstract is available for free and in plain > text.
