The Argentine Humming Dragon (Draco minimus floralis) was the smallest dragon. It was only 3 to 4 inches long and fed on insects. It could breathe fire and as a result they were used as "matches" because of their reflex flame in the early 19th century. The last sighting was in 1820. Some Dragonologist's suspect them to be living living in north america in the Nunavut Canada area but no official sightngs have been reported
