After examining the morphology of a male and a female specimen using a microscope, scientists identified several distinct features that are not found in modern species of assassin flies, including long flattened antennae and a unique v-shaped eye structure. National Museum of Natural History scientist Torsten Dikow discovered and named a new 100 million year old species of assassin fly, Burmapogon bruckschi, after studying the first two specimens ever preserved in Burmese amber.
