Common Mapwing

Nymphalidae; Nymphalinae; Cyrestini; Cyrestis maenalis maenalis Erichson, 1834. Wikipedia lists eleven C. maenalis ssp., six of which are documented present in the Philippines. Of those six, only one subspecies is present in the northern Philippines, where I live. So, there is no problem with distribution and since this butterfly has very distinct markings, the identification is pretty straight forward. However, when I went searching through some of my older photos of "True Brushfoot" butterflies (from the Subfamily Nymphalinae), I was not looking for easy identifications. I was looking for pictures which show the vestigial front legs. Anyone who is interested in butterflies will know that members of the Nymphalinae look like they have only four legs. This is because the front pair have, over aeons of evolutionary time, become so much shorter that they no longer function as legs. Most articles just say that they are so small that they are difficult to see. I had never seen these front legs until yesterday, but not because they are small, but because I was looking in the wrong place. Whenever I had a ventral view of a "Brushfoot" (which was not often), I was looking on the underside of the thorax, for a very short pair of vestigial front legs hanging downwards. I had no idea that they were usually hidden from view, by being "folded" or "curled" upwards over the front of the thorax. The fact that these little legs are nearly always "hairy" and are usually embedded in the hairy frontal part of the thorax, just made it almost impossible to see them. I only found out what to look for (and where to look) when I came across the article in https://rcannon992.com/2020/03/25/forelegs-and-four-legs-in-butterflies/..... I think it what is called a "Blog" and it is very informative.
