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. / Slim tube The body is a smooth tube with segments you can see, and shorter antennae and legs. Varies Inherited: Entomobryomorpha 4 Naked eye
Main colour Yellow Clearly yellow and not just cream. 2 Naked eye
Scales Scales present The body is covered in flat scales that give a shimmer or a tiled look. Inherited: Lepidocyrtus 4 Hand loupe
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 5 Stereo microscope
Eyes Eyes present Dark eye patches sit on both sides of the head. Inherited: Lepidocyrtus 4 Phone macro
Eye count Eight Eight dots in each eye patch, the most a springtail can have. Inherited: Lepidocyrtus 4 Stereo microscope
Mouth shape Blunt mouth The mouth is blunt and the head is rounded in front. Inherited: Entomobryomorpha 4 Hand loupe
Spines on the tail end No spines The last abdominal segment has no spines. Inherited: Entomobryomorpha 4 Stereo microscope
Jumping organ Long A long furca reaches forward under the body, and the animal springs when disturbed. Inherited: Lepidocyrtus 4 Hand loupe

The evidence in detail

Springtails US rates it Beginner level. Anecdotal 3
Model assumption Springtails US scores its reproduction rate 7 out of 10. The site reads that as fast growth and a high yield. Anecdotal 3
Springtails US cultures it on soil or clay. It advises moist substrate with minimal ventilation, and soil for the highest reproduction rate. The seller uses clay for this species. Anecdotal 3
Feed once or twice a week with a springtail food mix, brewer's yeast, another yeast or fish food. Anecdotal 3

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
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 Ideal fit
  • Sellers culture it damp all the way through. A substrate that stays damp is only a partial match.
  • Airflow is high. This species is usually kept with low airflow, which is a big difference.

Set by a curator: Springtails US has proven it in potted plants. It describes these springtails as small and gentle, able to roam onto dry soil between waterings. 1

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 Good fit
  • Sellers culture it damp all the way through, which suits a substrate that stays wet.
  • Airflow is low, which is what this species is kept with.
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 Good fit
  • Sellers culture it damp all the way through, which suits a substrate that stays wet.
  • Airflow is medium. This species is usually kept with low 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 Good fit
  • Sellers culture it damp all the way through. A substrate that stays damp is only a partial match.
  • Airflow is medium. This species is usually kept with low airflow.

Set by a curator: Springtails US pairs its semi-arid Lepidocyrtus with moisture-loving species and sends the Lepidocyrtus to roam the dry end of an isopod enclosure. 6

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 damp all the way through. A substrate that stays damp is only a partial match.
  • Airflow is medium. This species is usually kept with low airflow.
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 Marginal fit
  • Sellers culture it damp all the way through, so a substrate that stays mostly dry is a poor match.
  • Airflow is medium. This species is usually kept with low airflow.
Arid terrarium A dry, well ventilated desert terrarium with a hot basking spot, kept for bearded dragons and similar animals. See where it ranks Poor fit
  • Sellers culture it damp all the way through, so a substrate that stays dry is a poor match.
  • Airflow is high. This species is usually kept with low airflow, which is a big difference.

Open questions and sources

Open questions

  • Which species are the hobby *Lepidocyrtus* cultures named Micro Gold and Pearlescent?

    Identification Needs a specialist

    Why it matters. Both carry the label Lepidocyrtus sp. and they must not be merged just because they share a genus. Potted plant and isopod advice depends on knowing what they are.

    What would help. Slide-mounted adults compared with Lepidocyrtus keys, and a COI barcode from each culture.

  • 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.
