Triorla interrupta

This is the most commonly observed robber fly in Florida, likely because they frequent grassy berms where people hike, and because they are voracious predators and often take butterflies and dragonflies much larger than themselves. The black-banded abdomen with the last two segments entirely pale is distinctive. They could be confused for Machimus or Efferia, but Triorla are much larger.

Size: 20-25 mm

FL Season: April – December
