Season refers to each of the four divisions of the year (spring, summer, autumn, and winter) marked by particular weather patterns and daylight hours, resulting from the earth's changing position with regard to the sun.





For many of the species of butterflies such as Common Bushbrown and others, seasons effect the wing coloring patterns. Many of the butterflies has bright colors in wet season while dull colors in dry season. This is a defense mechanism to hide or camouflage from predators.





From the beginning of my butterfly photography i was watching something strange in case of Common Evening Brown. I have referred many books on Butterflies, i could see explaining Wet season format with silvery wings with some eye marks. While the books explains dull brown color in Dry season format. But it is true in almost all Bushbrowns. What is special about Common Evening brown? Look at the photographs which i uploaded below for discussion. I have photographed both butterflies on the same spot on 1st November 2016, in my garden.









My question is Which is Male and Which is Female? How Both the butterfly specimens appeared in the same season? What makes one butterfly immune to seasonal change? My observation is Dry season Format of Common Evening Brown as explained in books , Out numbers Wet season format at the same place? Whether Dry season format is observed anywhere in Wet season? If NO is the answer, is it true that Male or Female is immune to seasonal change?

I am asking questions to experts and amateurs in the field of butterfly field surveyors.
