Small dark scorpions of the North American west, crevice-dwellers of rock and litter from California through the borderlands, mild in venom and modest in every dimension except longevity.
They keep like temperate animals: cooler and moister than desert defaults, cork and stone cover, patience. Sedentary, long lived, and about as low-risk as the order offers, in the same practical tier as the European wood scorpions.
Collection is thin and local, often incidental, and the trade is a specialist's margin: single listings, soft species identification resting on collection locality, and prices formed by whoever bothered to collect. The genus sells to keepers assembling the finely divided North American shelf, and the market is exactly that size.
The line on each tile: lowest ask per day.
Rarity BETA Rarity is supply, and only supply: the tier is how many sellers have ever carried a species, and for a single seller, how many separate listings. Price is not part of it, and neither is how recently it appeared. Tiers are given to tarantula species only.
