I found some insects after moving into a new apartment in south eastern Brazil, in an urban center. It is the 11th floor (relatively high up) but very windy region. Some loose wings can be found around the house. I'm not sure if they are being blown through the windows or if we have an infestation somewhere.
Some individuals were found inside bathroom cabinets. I've found two live ones with wings last night, one of which is shown in the pictures. A dead one without wings was also shown.
