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.

Staples
Ambient mould / biofilm in the cultureLeaf litter & fine decaying matter
Protein

Not needed as such — a light weekly dusting of brewer's yeast is the standard "feed".

Calcium

Not required.

Favorites
Brewer's yeast (tiny weekly dusting)Rice flourSpirulina powderPowdered fish flakes / sinking fish foodMushroom
Avoid
Overfeeding (mould blooms + grain mites)Standing water (drowns / suffocates them)Chlorinated tap water — use dechlorinated / ROHeat mats & direct sun

Environment

Ventilation

A ventilated lid — a little airflow prevents anaerobic crashes, but keep it humid. Never let it go stagnant or bone dry.

Setup

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.
