The wheel bug: North America's largest assassin bug, armored, gear-crested, and carrying a defensive bite that is genuinely, memorably painful, routinely described as worse than a wasp sting and slow to fade. That matters because the animal's deliberate movements invite the handling that causes it.
Keeping is simple: a ventilated enclosure, climbing structure, and live prey, which it dispatches with a violence that makes it one of the more watchable insects available. Forceps for all maintenance.
Supply is seasonal wild collection, the lifespan is a single year, and eggs overwinter, which shapes the annual market: nymphs in spring, adults through summer, nothing after frost. Priced by abundance, bought for the spectacle, and respected for the rostrum, in that order.
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.
