The big garden mantids, including the Chinese mantis naturalized across North America, and the one genus in the order that trades as much in egg cases as in animals.
Mantid rules whole: annual lifespan, molting height, flying prey, nymphs over adults. An ootheca is a hundred mantises with a hatch date, which is the genus's distinctive product and its own management problem.
Agricultural ooth supply keeps this the most abundantly available mantis lineage on the continent, seasonally and permanently, and the market prices accordingly: near the floor that farm-scale production enforces, with the hobby premium reserved for named nymphs. A year of the most-watched insect in the garden, sold by the season.
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.
