Chloealtis is a of slant-faced grasshoppers in the Acrididae, containing approximately five described . Species in this genus are associated with forested and mountainous in western North America. The genus has been studied extensively for its unusual meiotic , particularly regarding synaptonemal complex formation and nuclear envelope attachment during division.

Identification
Members of Chloealtis can be recognized as slant-faced grasshoppers, a group characterized by an inclined or sloping facial profile. The belongs to the tribe Chrysochraontini within the Gomphocerinae. Specific identification to level requires examination of detailed morphological characters not documented in available sources.

Habitat
Forest openings and low brush in mountainous regions; specifically documented in ponderosa pine-grassland and small forest clearings. Two (C. abdominalis and C. conspersa) are recorded from the Black Hills, Big Horn Mountains, and Medicine Bow Mountains of Wyoming.
Distribution
Western North America. Documented occurrences include Wyoming (Black Hills, Big Horn Mountains, Medicine Bow Mountains), Colorado, and additional records from California, Illinois, Indiana, and Massachusetts. Distribution is primarily associated with montane and submontane zones.
Seasonality
present from mid-July to September. overwinter and hatch in spring.
Diet
Grasses. Chloealtis conspersa has been observed to prefer bluegrass (Poa ).
Life Cycle
are laid in soft wood on the ground, occasionally in soil or dry . Eggs overwinter, with hatching in spring. Development proceeds through nymphal stages to in mid-summer.
Ecological Role
Herbivore in forest-grassland . Low densities prevent significant competition for rangeland forage.
Human Relevance
Minimal economic impact; are rarely abundant enough to cause forage damage except in combination with other .
