Nature: Butterflies and Moths

Pearly Wood Nymph 珍珠木仙女 (Family Noctuidae, Nocturnal Moths)

In the dark shadows of the night loveliness may surround us and we would not know it. This beautiful night moth, like a pearl hidden in the folds of an oyster, must be searched out and found in the darkness to be appreciated. Such a moth sometimes comes to a light, but more often it is captured by putting out a sweet bait on tree trunks to which the moths come. Such a bait is one made of a mixture of decaying bananas, fermented beer and molasses, which some moths seem to love. The collector then goes out very quietly in the night darkness, carrying a flashlight, turning the light carefully on the trees where the bait has been put. What a mysterious adventure this becomes when you see such beauties of the night as the Pearly Wood-nymph of the under-wing moths sipping greedily at the sweet lure.

The under-wings are duller than the bright-colored upper-wings so that their defense against enemies is not often to fly from them, but to hide quickly in the grass or flowers, cling to a stem and fold the wings together. The dull colors merge with the foliage around them, hiding them. But sometimes one is seen to fly right into the heart of a copper-colored flower and then the wings are spread flat so that the bright upper wing color merges with the flower’s bright colors.

Lung Cancer is the most common type of cancer in the world as evidenced by 46,403 new cases diagnosed in the United Kingdom in 2014 as per Jones & Baldwin (2018). Incidence of Lung Caner had shifted from a marked decline in the male population to an increased incidence in the female populace. There is also an improved survival rate of Lung Cancer among patients who have been diagnosed of the disease at different stages from 24.5% to 36.7% in 1995. This one-year survival rate has been attributed to the advancements in diagnosis and treatment (Gavin &Baldwin,2018).
