Neobarrettia
arid-land katydid, spiny predatory katydid
Neobarrettia is a genus of nine North American predatory katydids distinguished by prominent spines and powerful mandibles adapted for carnivory. These insects inhabit arid and semi-arid regions from the southwestern United States through Mexico. They are known for aggressive threat displays and the ability to inflict painful bites when handled.

Greater Arid-land Katydid, Red-eyed Katydid, Red-eyed Devil, Giant Texas Katydid, Spiny Bush Katydid
Neobarrettia spinosa is a large, predatory katydid native to the southwestern United States and northern Mexico. Unlike most katydids, it is an obligate carnivore, actively hunting and consuming prey including other insects, small vertebrates, and even endangered songbirds. The species is notable for its striking threat display, during which it rears back, spreads its wings, and exposes its bright coloration while presenting formidable mandibles and spiny forelegs. It is one of only two Neobarrettia species extending into the United States from a genus otherwise restricted to northern Mexico.

Neobarrettia victoriae
lesser arid-land katydid
Neobarrettia victoriae is a large, spiny predatory katydid known as the lesser arid-land katydid. It is one of two North American species in the genus Neobarrettia, both characterized by robust bodies, powerful mandibles, and spiny forelegs adapted for capturing prey. Unlike most katydids, this species is an obligate carnivore. It occurs in arid and semi-arid regions of the south-central United States and Mexico.

Polistes dominula
European Paper Wasp
Polistes dominula is a highly successful invasive social wasp native to Eurasia that has established populations across North America, South America, New Zealand, South Africa, and other regions. First detected in North America near Boston in 1978, it has become one of the most abundant wasps on the continent. The species builds small, exposed paper nests in protected locations and preys primarily on live insects, particularly caterpillars. Unlike yellowjackets, it does not scavenge for meat or sugar. Its rapid spread has been attributed to ecological flexibility, superior competitive ability, and tolerance of human-altered environments.
