Small moths walking on bat guano. Even when disturbed, the moths did not fly. They mainly walked slowly and used their antennae to explore their surroundings.
together with and very similar to www.ispot.org.za/node/234766 but that one was yellow and this one is pale brown and the photos of this one are not so good
Moths attracted to outside light of cottage in natural veld but adjacent cropland. Naughty did not have ruler! The bumps on the wall are 1-2mm across. Although slightly different I assume all three are the same?
