I'm going to reach a little bit here but the quirkiness of Sonoran life is often explained by history. I don't know about other species habitats but Arizona was a tropical rain forest very recently in geological history (as little as 9,000 years ago). It is reflected in Sonoran biodiversity in many ways. There is even a species of parrot and tree frog here. My intuition is to attribute the need for high humidity during molt to a throwback from the rain forest that hasn't been selected out because of the high humidity and moisture during the summer monsoons.Not saying if you are right or wrong, but I have seen this before and I have an inquiry. If humidity (or lack thereof) is playing a large role in the low molting rate of H. arizonensis in captivity, I am wondering why other arid species such as Smeringurus mesaensis don't seem to share this same high level of difficulty.
Actually a pretty interesting set of thinking. Even though I still wonder why it only affected that species and not the other species that are from the same area as H. arizonensis.More on the tropical interglacial periods of the Sonora and Mojave deserts in the Holocene era (11,000 yrs to present):
Surprisingly, the vertebrate fossil record suggests that some interglacial climates were more tropical during the Holocene. El Golfo de Santa Clara is near the mouth of the Colorado River in northwestern Sonora. Early Pleistocene (1.8 mya) fossils reflect a climate that was frost free, with much greater rainfall in the warm season, and with higher humidity than today. Greater summer rainfall would suggest that tropical oceans were warmer than they are today, in contrast to most of the Pleistocene when ocean waters were colder. The fauna included such mammals as antelope, bear, camels (dromedaries and llamas), cats, horses, proboscidians, and a tapir (Tapirus). The giant anteater, capybara (Neochoerus), and ground sloths in the fauna were members of ten families of mammals that immigrated into North America in the late Pliocene or early Pleistocene after the opening of the Panamanian land bridge during the Great American Interchange. In contrast, the imperial mammoth (Mammuthus imperator), a hyena (Chasmoporthetes johnstoni), and jaguar (Felis onca), were Eurasian immigrants. The nearest populations of giant anteater are 1800 miles (3000 km) to the southeast in the humid, tropical lowlands of Central America! As for many large mammals, the modern distribution may not accurately reflect their physiological range limits because of human predation in the last 11,000 years. Other fossils in the fauna include the Sonoran Desert toad (Bufo alvarius), slider �turtle�(Trachemys scripta), boa constrictor (Constrictor constrictor), and the large extinct California beaver (Castor cf. C. californicus). The Sonoran Desert toad is a regional endemic, while the slider and boa constrictor occur today in Sonora in wetter, more tropical areas to the southeast. Although the El Golfo area is today part of the hyperarid Gran Desierto, the delta of the Colorado River was historically a very wet area that supported extensive cottonwood (Populus fremontii) gallery forests with abundant beaver. There is even a December 1827 account of a large spotted cat (likely a jaguar) that entered James Ohio Pattie�s camp on the Colorado River south of Yuma to feed on drying beaver skins.
That would be the best thing to do lol. Mine hides under a log and comes out anytime I move the cage to check on her.So I have found him and placed him inside a plastic critter keeper for a short while. I wanted to make sure he had eaten as had been in transit. Fed and hopefully happy
