Grylloblatta
ice crawler, rock crawler
Grylloblatta is a genus of ice-crawlers comprising 15 described species endemic to western North America. These insects represent an ancient lineage with obligate physiological dependence on stable near-freezing temperatures, with acute thermal tolerance between approximately -8.5°C and 10°C. The genus exhibits deep genetic subdivision and geographic structure, with diversification patterns tied to Pliocene-Pleistocene glacial cycles. Species occur in montane habitats, ice caves, glaciers, and subalpine forests, with some populations utilizing saproxylic habitats in beetle-killed trees.

Grylloblatta chintimini
Marys Peak Ice Cricket, rock crawler
Grylloblatta chintimini is a species of rock crawler (family Grylloblattidae) described in 2015 from Marys Peak in the Oregon Coast Range. It is one of the most recently described species in this relict insect order, bringing the total number of Grylloblatta species to 15. The species occurs in a restricted alpine habitat on persistent snowpack near the 1250 m summit. Like other grylloblattids, it is adapted to cold, moist environments and is considered a living fossil representing one of the most basal lineages of winged insects.

Grylloblatta chirurgica
Mount Saint Helens Grylloblattid, Mount Saint Helens grylloblatid
Grylloblatta chirurgica is a species of ice crawler endemic to southwestern Washington state, specifically associated with high-elevation habitats and ice caves near Mount St. Helens in Skamania County. Described by Gurney in 1961, it is one of the rarest and most geographically restricted members of the relict order Notoptera (Grylloblattodea). The species persists in cold, stable microhabitats including glacial ice fields and subterranean ice formations. Its extremely limited distribution and specialized habitat requirements make it vulnerable to environmental change.

Grylloblattodea
ice crawlers, rock crawlers
Grylloblattodea is a small order of extremophile insects commonly known as ice crawlers or rock crawlers. These wingless insects are adapted to cold environments and are found in montane habitats, caves, and subalpine forests across western North America and northeastern Asia. The order comprises approximately 25-30 described species in five extant genera, though significant undescribed diversity is suspected. Grylloblattids are predatory, feeding on other arthropods, and show remarkable cold tolerance. They are considered a relict lineage with ancient origins, closely related to Mantophasmatodea within the clade Xenonomia (order Notoptera).

Gryllotalpa major
prairie mole cricket
Gryllotalpa major, the prairie mole cricket, is the largest cricket species in North America, endemic to the tallgrass prairie ecosystems of the south-central United States. Males exhibit a classical lekking mating system, constructing specialized acoustic burrows that amplify their calling songs to attract flying females from distances up to 400 meters. The species is threatened by habitat loss due to prairie conversion, with current populations restricted to fragmented sites in Oklahoma, Kansas, Missouri, Nebraska, and Arkansas. Research has documented unique acoustic behaviors, including harmonic chirps rather than trills, and vibrational communication between neighboring males through the soil.

Hypochilus
North American lampshade spiders
Hypochilus is a genus of North American lampshade spiders (family Hypochilidae) comprising eleven described species, all endemic to the United States. The genus is a relictual lineage with a disjunct distribution across three montane regions: California, the southern Rocky Mountains, and the southern Appalachia. Hypochilus species exhibit extreme genetic divergence coupled with striking morphological conservatism, creating persistent challenges for species delimitation. These spiders are textbook examples of short-range endemics with naturally small geographic ranges and strict microhabitat specialization.
