Tropical bugs?

We learned during our first week at the university here that having the lights on at night, especially outdoor, can be disastrous. Since our bathroom and kitchen are both outside the dorm room in the balcony, lights on in the evening had attracted these flying insects without our knowing it, until one night, perhaps during one of their peak breeding seasons, there were so many of them we couldn't even go outside to do dishes or wash up. We just climbed inside our mosquito nets and slept early, waking up in the morning only to find all the bugs dead everywhere. I swept some of them up in a pile as shown. Now we learn to do all the cooking before sun down and keep the lights off while I do dishes. We are told they are here all year round and are to learn to live with them even though they only live overnight...
