What’s going on with the world’s butterflies?
The world’s most common butterfly species, the common buttercup, has recently been seen in parts of Europe and Asia.
Scientists are not sure what causes the butterflies to turn yellow, which is the color of the virus.
So what’s causing the virus to cause butterflies to get yellow?
The answer is that, when they are exposed to the virus, the butterflies lose their natural protective immunity.
That means that, because they are so susceptible to the infection, the virus may not only trigger their immune system to produce antibodies, but may also increase their ability to cause more of them.
The virus also makes the butterflies vulnerable to a host of other viruses, including bacteria, viruses, and protozoa.
In fact, researchers say the butterflies can even become infected with other species of viruses that can cause disease in humans.
So it’s a pretty complex story, but scientists say they do know that the butterflies are vulnerable to infections with viruses like coronavirus and SARS-CoV-2, as well as with other protozoan viruses.
And the butterflies also become more vulnerable to viruses when they have high levels of a protein called cyclin D1.
That protein, which helps the butterflies’ immune systems to fight infections, may also be responsible for the butterflies becoming yellow.
