Nomotettix cristatus
crested pygmy grasshopper, crested grouse locust, northern crested grouse locust
Nomotettix cristatus is a small pygmy grasshopper in the family Tetrigidae, commonly known as the crested pygmy grasshopper or crested grouse locust. It is one of approximately 35 Nearctic species of Tetrigidae. The species exhibits three recognized subspecies with distinct geographic distributions across North America. Like other members of its family, it is characterized by an elongated pronotum that extends over the abdomen, a trait distinguishing pygmy grasshoppers from typical grasshoppers in Acrididae.

Trichosirocalus
rosette weevils, crown weevils
A genus of small true weevils native to the Palearctic region. Several species have been widely introduced to North America, Australia, and New Zealand as biological control agents for invasive thistles. The genus was historically treated as containing a single species, T. horridus, but integrative taxonomic studies using molecular and morphological data have revealed multiple distinct species with different host associations.
