A praying mantis is named for the typical “prayer-like” stance. The word mantis derives from the Greek word mantis for prophet or fortune teller. Being an insect the praying mantis has three parts to its body. The head, thorax and abdomen. The abdomen is elongated and covered by the wings in adults. Females have strong and large cerci. The first thoracic segment, the prothorax, is elongated and from it arises the modified foreleg.
There are many different species of duck. The White-winged Wood Duck, is a species of duck that many researchers associate with the dabbling ducks. However the biogeographical pattern of distribution indicate that the anatomical similarity to the Muscovy Duck is deceiving.
Thus, this species might more appropriately be placed in an unrelated to the Muscovy Duck but closer to the diving ducks. Historically, the White-winged Wood Duck was widely distributed from north-east India and Bangladesh, through South East Asia to Java and Sumatra.
