The black saddlebags (Tramea lacerata) is a species of skimmer dragonfly found throughout North America. It has distinctive wings with characteristic black blotches at their proximal ends, which make the dragonfly look as though it is wearing saddlebags.
The black saddlebags is a relatively large dragonfly at about 5 centimetres (2 in) in length. The body is thin and black, and the female may have lighter spotting or mottling dorsally. The head is much wider than the rest of the body and is dark brown in color.
The insect can be found at bodies of stagnant water, such as ponds and ditches. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Black Saddlebags is recorded against all the insects logged in Miami (11 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
