Blue Velvet
Desoria trispinataRare deep-indigo "velvet" temperate springtail — active and UV-fluorescent.
Overview
Desoria trispinata (Blue Velvet), a temperate springtail with a muted indigo-blue "velvet" colour; active, on the larger side, and it fluoresces under UV light. A North American species (commonly a Chicago, IL locality) prized for looks as much as cleanup.
Diet
Grazers on mould, yeast, fungi, biofilm and fine decaying matter — the bioactive cleanup crew and a micro-feeder. Feed lightly; the culture itself grows most of their food.
Not needed as such — a light weekly dusting of brewer's yeast is the standard "feed".
Not required.
Environment
A ventilated lid — a little airflow prevents anaerobic crashes, but keep it humid. Never let it go stagnant or bone dry.
A deli cup (small) or 6qt tub (production) with a moist medium, kept in low, indirect light out of direct sun.
Substrate
Classic method is horticultural charcoal kept wet (holds moisture, huge microbial surface); or a moist coco / soil + leaf-litter medium for the more soil-loving tropical species. Consistently damp, never standing water.
Temperament
An active, striking temperate display species — fun under a UV light.
Breeding
Steady in a cool, damp culture.
Growth
Moderate — cool-loving; a damp charcoal / soil medium suits it.
Common mistakes
- ✕Overfeeding → mould and grain-mite outbreaks.
- ✕Standing water → anaerobic crash.
- ✕Letting it dry out completely.
- ✕No ventilation → sour smell and die-off.
- ✕Chlorinated tap water — always dechlorinate or use RO.
Pro tips
- ✓Keep a backup culture split off your strongest bin.
- ✓Harvest by tapping (they climb the sides) or floating with a little water.
- ✓Re-seed vivariums every 2–4 weeks for continuous mould control.
How sources agree
Sources agree Blue Velvet is a rare, active, deep-blue temperate springtail (Desoria trispinata, often a Chicago locality) that fluoresces under UV, on standard cool-side springtail care.
