We are two ecologists from Bangladesh who have started a small initiative (voluntarily)- that is to identify different species which live in our capital city Dhaka (urban biodiversity) using facebook group. We call it “Life in the midst of a concrete jungle”. The idea is that members will submit some photos and we will try to id them or find people who may help us. Sometimes, especially with arthropods its very difficult. Thus we are asking for your help. The quality of some of the photos may be quite bad for which it may be quite difficult. So even genus level would be quite good. Thank you in advance.

Dear Sate & Mofiz,
Your project sounds marvelous. Both of your butterflies are in the family Nymphalidae, the Brush-Footed Butterflies, and they are characterized by having their first pair of legs atrophied and useless for walking, so they appear to have only four legs. We started our search on the Butterflies of Bangladesh website, and we clicked through all the members of the family Nymphalidae before coming to the conclusion that at least one of your butterflies is a Common Evening Brown, Melanitis leda. According to the Butterflies of Bangladesh: “Status: Very common. Habit and Habitat: Found in all types of habitat from grass land, cultivated land, bushes, homestead gardens, plain land forest to hill forests. In the day time it is hide with in dry leaves, which is difficult to identify. Become active before evening. Often seen come home attracted by light. Fond of rotten fruit and tree exudates.” As you can see from the images on the Butterflies of Bangladesh site, this is a highly variable species. We tried to find other examples online that more closely resembled the two images you submitted. SambuiButterflies has an image with color and markings nearly identical to the image you provided of the Common Evening Brown resting on a leaf, a the site states: “Not uncommon species with an enormous variety of underside patterns.” Project Noah has an image that resembles the markings on the individual resting on the stucco wall. We believe your moth is in the family Lasiocampidae.
Dear Mr. Marlos,
Thank you so much for this! We really appreciate it.
