An incredibly tiny bird (even smaller than our Calliope Hummingbird), native to the mountains of Mexico. Well named, it suggests a large insect in flight. More than a century ago, in 1896, two individuals reportedly were found in southern Arizona; some experts doubt this record. There have been no confirmed records north of the border in the time since.
