Why: There is some evidence that omega-3 fatty acids may ease anxiety symptoms and lift your mood by lowering levels of stress chemicals such as adrenaline and cortisol in the body. Caned fatty fish, such as tuna and salmon, walnuts, and flax seeds are all great sources of omega-3 fatty acids.
As you may already know from reading How Butterflies Work or Where do butterflies get their striking colors?, butterfly wings are made of very thin layers of a hardened protein called chitin.
Adult Moths and Butterflies all have large wings that are covered with tiny scales. Each scale has a color, and together they give these insects their amazing wing patterns. No other insect groups have this coating of scales on their wings. Butterflies hold their wings up and down over their backs, while moths usually hold them folded down flat. Color patterns vary a lot, but like the caterpillars, they are usually either camouflaged or bright with warning colors.
