Megatibicen pronotalis
Walker's Annual Cicada, Walker's cicada
Megatibicen pronotalis, commonly known as Walker's Annual Cicada or Walker's cicada, is a species of cicada in the family Cicadidae. It is found in the northern Great Plains of the United States and has been reported from states including Illinois, Kansas, Kentucky, Alabama, and Florida. Males produce sound using tymbals—hardened membranes under plates on the venter at the base of the abdomen—and are reportedly among the loudest insects in the world. The species is often associated with riparian cottonwood (Populus) and willow (Salix) habitats.

Mestra
Arizona Sister, Curve-winged Metalmark
Mestra is a genus of butterflies in the family Nymphalidae, subfamily Biblidinae, established by Jacob Hübner in 1825. The genus contains several species distributed primarily in the Americas, with the most well-known being Mestra amymone, commonly called the Arizona Sister or Curve-winged Metalmark. These butterflies are medium-sized with distinctive wing patterns and are associated with specific host plants in their larval stages. The genus name derives from Greek mythology, referencing Mestra, daughter of Erysichthon, who possessed the ability to change her shape at will.
