Wings in a New Light
The peppered moth lands on the bark of a tree trunk and opens its wings to rest. A hungry flycatcher bird that was close behind swoops down for a meal but loses sight of its prey. The moth blended in with the tree trunk. Blending in let it avoid the pesky flycatcher, so the moth lives to see another day. This may seem like a simple act of nature, but scientists are quite curious about how and why these sorts of interactions arise.
