The best Christmas trees are made with butterflies, according to a study published in the Royal Society journal Biology Letters.
The study was based on a team of scientists from Oxford University and the National Institute of Botanical Gardens in Cambridge, UK, who tested and analysed the results of more than 300 butterfly research projects around the world.
The researchers found that when it came to choosing the best butterflies to decorating your tree, there was little consensus, with researchers in Germany and the US finding the most common choices to be either the black-and-white butterfly or the yellow-and.
Butterflies are highly visual creatures that are highly sensitive to light.
When exposed to bright light, they can change colour, such as the golden colour of the sun, or become red, white or blue.
This can then be mistaken for a real tree, even though they may have been deliberately painted over.
It’s a common mistake, because when you paint a tree with the wrong colours, you end up creating the wrong shade of colour for the tree, which will then be completely invisible.
This is why it’s important to choose the right butterflies.
The black- and white butterfly has a more pronounced yellow colour, and the yellow colour of a yellow butterfly can be mistaken as a real colour, according the study.
Researchers found that a lot of the time, the butterfly choice came down to the price of the butterflies and the type of tree they were placed on.
The white butterfly, for example, costs £1.70, compared with £1 for a yellow- and red-bodied butterfly.
Butterflies can be purchased for £5, compared to the £10 for a green-and coloured butterfly.
However, if you want to use a butterfly from the more traditional variety, it’s a good idea to make sure that the butterfly you choose is a real butterfly, and that it has a clear white border around its eyes, neck and wings.
