“ Blue butterflies: A type of butterfly with blue wings which are fed with the flowers grew on the graves. But what is the relation with this massacre in Bosnia? “During the Srebrenica massacre (1995) using excavators and bulldozers, Bosnian Serb forces dug deep pits and buried Bosnian victim bodies by piling them up by the dozen in several mass graves. A year after the genocide, the search for missing persons grew desperate but no one knew what fate they had met. In July 1996, however, Amor Masovic, who was part of a UN-approved team of war crime investigators, discovered a "surface mass grave" in which 266 bodies were found. All the victims were Bosniak Muslims who were killed by Serbian forces in cold blood. In the years that followed, more mass graves were uncovered across the country. Some Bosnians narrated different versions of how quite so many of the graves were found. One of the most intriguing oral histories on the search for mass graves featured blue butterflies and Artemisia, a weed that commonly grows in graveyards. In Bosnia, a few years after the massacre, some villages and towns witnessed a sudden surge of blue butterflies. In a bizarre turn of events, this swarm led investigators to mass graves. Although the claim sounds mythic, a Bosnian author, Zeynep Hamzic, wrote an article in August 2015, in which he stated that out of "500 mass graves that were found in Bosnia, 300 were found with the help of blue butterflies". “ Of course, not all graves were found like this. Unfortunately, there are still people waiting to be found. Not only with the help of these butterflies, but also with various excavations and some natural events, mass graves are unearthed. In 2015 the extraordinarily hot temperatures meant the heat dried up the sludge, making the earth crack, and exposing the human bones underneath. The situation is so complicated that sometimes it was taking time to find these complex bones by DNA analysis, as the corpses in some mass graves were transported from one mass grave to another. Amid all these horrors, the blue butterflies have been a source of hope and symbol for the relatives of the Bosnian victims.
