Camponotus floridanus
Florida Carpenter Ant
Camponotus floridanus, the Florida carpenter ant, is a large, conspicuous ant species native to the southeastern United States. It is notable for its striking bicolored appearance—reddish-orange head and mesosoma contrasting with a black gaster—and its highly aggressive defensive behavior. The species exhibits pronounced worker polymorphism with distinct minor and major castes, and maintains an obligate mutualism with the endosymbiotic bacterium Blochmannia floridanus. Colonies are fast-growing and can reach thousands of individuals, with unique behaviors including surgical amputation of injured nestmate limbs to prevent infection.
Ovalipes ocellatus
Lady Crab, Ocellated Crab, Calico Crab, Leopard Crab, Atlantic Leopard Crab
Ovalipes ocellatus, commonly known as the Lady Crab, is a medium-sized crab species native to the western Atlantic coast of North America. The species is distinguished by its yellow-grey to light purplish carapace adorned with distinctive leopard-like clusters of purple spots, which provide limited iridescence for signaling. It is primarily nocturnal and often buries itself in sandy substrates. The species has been described as notably aggressive toward humans, with documented instances of pinching waders.
Vespula maculifrons
Eastern yellowjacket, Eastern yellow jacket
Vespula maculifrons is a social wasp native to eastern North America, commonly known as the Eastern yellowjacket. It is among the most aggressive stinging insects in its range, known for vigorously defending nests and delivering painful stings with minimal provocation. Colonies are typically founded by a single queen in spring and can grow to contain thousands of workers by late summer. The species is polyandrous, with females mating with multiple males, and exhibits cooperative colony dynamics without significant reproductive conflict among patrilines.
