Greetings, The other bug that is attracted to you is probably what they call the no seeums. They are attracted to the warmth of your body which is called thermotrophism, They are from the Family Ceratopogonidae. The adults are small vicious blood suckers. The adults can transmit viral diseases. The wings are held flat over the abdomen The larvae breed in aquatic areas or in wet soil along water. http://wcb.ucr.edu/wcb/schools/CNAS/entm/rredak/1/files/lect15.html Many insects seem to be attracted to or repelled by light (phototropism). Moths are attracted to artificial light and moonlight but avoid sunlight. Butterflies react in the opposite way. Cockroaches in a dark room hide when a light is turned on. Many people worry that headlice can be caught from "common areas" such as lounge & car seats. The likelihood of this occurring is very low. Headlice are "heat-seeking" insects, & will generally not leave the head at all, unless of course, it is to move to a better looking head (!) Even if they do happen to land on your lounge, carpets or car seats, they will not last longer than 48 hours off the head. http://www.banlice.com.au/htm/how_do.htm Here are some interesting facts about Moths and their attraction to light Moths navigate using the light of the Moon as a steady reference point; they fly in a straightish line keeping the Moon on one side. When a bright artificial light is present they try to do the same thing - but to keep it in a fixed position they end up flying round in circles. The brightness of the light disorientates them and their orbits get smaller and smaller until eventually they hit the light. Moths became nocturnal during evolution; this is a behavioral adaptation which avoids daytime predators. Which are more numerous than their night-time counterparts. To allow communication in the dark, many moths species have pheromonal ('smelly hormone') systems whereby individuals can detect each other from distances of several kilometres. http://www.sciencenet.org.uk/database/Biology/Original/b00109d.html Check out the following site to find out how to build a moth trap. http://www.bbc.co.uk/science/scienceshack/experiments/mamothtrap.shtml Thanks for taking the time to send in a question to the Mad Scientists Network.
