North America's small bark centipedes, finger-length, blue-grey, and the mildest common centipedes on the continent.
The genus rules are the family rules at miniature scale: fast, escape-capable, and venomous enough to make a bite unpleasant rather than eventful. Bark cover, mesic setups, and lids tested with the same seriousness as for the giants, because the speed did not shrink with the body.
Seasonal eastern collection carries deep supply, nobody breeds them, and the structure is the permanent US-native one. Within the centipede shelf this is the entry point priced by abundance, and the standing genus-family warning still applies in scaled form: there is no handleable centipede.
