Identification

No source read for this site describes the colour of this species. Unknown Open question What do *Seira purpurea* and *Seira brasiliana* look like in culture?

Characters to check

These are the features recorded for this species. Each row says what kit you need to read it.

Character What it looks like Needs
Body form Long and slim The body is long and slim with clearly visible segments, long antennae and long legs. Inherited: Seira 3 Naked eye
Scales Scales present The body is covered in flat scales that give a shimmer or a tiled look. Inherited: Seira 3 Hand loupe
Antenna length Longer than the body The antennae are clearly longer than the whole body. Inherited: Seira 3 Phone macro
Antenna segments Four plain segments The antenna has four clear segments and none is divided into rings. / Divided into rings At least one segment is split into small rings, which makes the antenna look jointed. Varies Inherited: Collembola 4 Stereo microscope
Eyes Eyes present Dark eye patches sit on both sides of the head. Inherited: Seira 3 Phone macro
Eye count Eight Eight dots in each eye patch, the most a springtail can have. Inherited: Seira 3 Stereo microscope
Mouth shape Blunt mouth The mouth is blunt and the head is rounded in front. Inherited: Entomobryomorpha 3 Hand loupe
Spines on the tail end No spines The last abdominal segment has no spines. Inherited: Entomobryomorpha 3 Stereo microscope
Jumping organ Long A long furca reaches forward under the body, and the animal springs when disturbed. Inherited: Seira 3 Hand loupe

The evidence in detail

Springtails US rates it Intermediate plus level. Anecdotal 2
Model assumption Springtails US scores its reproduction rate 3 out of 10. The site reads that as slow growth and a low yield. Anecdotal 2
Springtails US cultures it on soil. It advises a moisture gradient with about 75% of the substrate dry, plus a large amount of ventilation on the dry side. Anecdotal 2
Feed once or twice a week with a springtail food mix, brewer's yeast, another yeast or fish food. Anecdotal 2

Fit by enclosure type

A model estimate from the climate each enclosure type holds and the ranges recorded for this species. It is not a measurement.

Enclosure type Fit Why
Arid terrarium A dry, well ventilated desert terrarium with a hot basking spot, kept for bearded dragons and similar animals. See where it ranks Good fit
  • Sellers culture it with 75% of the substrate dry, which suits a substrate that stays dry.
  • Airflow is high, which is what this species is kept with.
Semi-arid terrarium A mostly dry terrarium with a damp hide and a warm spot, kept for leopard geckos and similar grassland or scrub animals. See where it ranks Good fit
  • Sellers culture it with 75% of the substrate dry, which suits a substrate that stays mostly dry.
  • Airflow is medium. This species is usually kept with high airflow.
Potted plant A houseplant pot with an open top, watered on a schedule so the soil dries a little between waterings. See where it ranks Marginal fit
  • Sellers culture it with 75% of the substrate dry. A substrate that stays damp is only a partial match.
  • Airflow is high, which is what this species is kept with.
Open tropical terrarium A tall terrarium with mesh ventilation and daily misting that dries out between sprays, kept for crested geckos and similar climbers. See where it ranks Marginal fit
  • Sellers culture it with 75% of the substrate dry. A substrate that stays damp is only a partial match.
  • Airflow is medium. This species is usually kept with high airflow.
Isopod tub A ventilated tub of organic substrate and leaf litter with a damp end and a dry end, kept for isopod colonies. See where it ranks Marginal fit
  • Sellers culture it with 75% of the substrate dry. A substrate that stays damp is only a partial match.
  • Airflow is medium. This species is usually kept with high airflow.
Temperate woodland vivarium A cool, damp vivarium with leaf litter, bark and a moisture gradient, kept for fire salamanders and similar woodland amphibians. See where it ranks Marginal fit
  • Sellers culture it with 75% of the substrate dry, so a substrate that stays wet is a poor match.
  • Airflow is medium. This species is usually kept with high airflow.
Closed tropical terrarium A glass terrarium with a lid and little ventilation, misted often, kept for dart frogs and other animals from humid forest. See where it ranks Marginal fit
  • Sellers culture it with 75% of the substrate dry, so a substrate that stays wet is a poor match.
  • Airflow is low. This species is usually kept with high airflow, which is a big difference.

Taxonomy and naming history

The original identification as Seira sp. 13 came from macrophotography. A 2026 update confirmed Seira purpurea by microscopy. The seller says it has not been sold widely, so the change should cause little confusion. Anecdotal 1, 5

Open questions and sources

Open questions

  • What do *Seira purpurea* and *Seira brasiliana* look like in culture?

    Identification Open

    Why it matters. Both were named by microscopy in 2026 and no source read for this site describes their colour. They share a genus and look alike in photographs.

    What would help. Scaled photographs of live adults and the species descriptions.

  • Which species is this culture, checked by a specialist?

    Identification Needs a voucher specimen

    Why it matters. Hobby cultures are mostly named from a seller's label or a photograph. A wrong name spreads from seller to keeper and then into care advice.

    What would help. Preserved vouchers from the culture in 80 to 95 percent ethanol, mounted specimens examined by a springtail specialist, and a DNA barcode where a reference exists. Deposit the voucher with a museum or a university collection.
