Scientific name

Trachelipus ratzeburgii

The selected documents describe a Trachelipus associated with forests. This profile’s value is linking a verified taxonomic name to shelters actually described, without assigning it another member of the genus’s conditions. [1][2]

Origin

Central and eastern Europe in Schmalfuss’s world catalogue. [2]

  • Forest-dwelling
  • Wood and litter
  • Discreet observation

Natural-history or taxonomic sources distinguished from breeding accounts; captive limits explicit.

At a glance

Trachelipus ratzeburgii is associated with forest shelters; wood crevices can provide retreat when disturbed. [1]

ADULT SIZE12–16 mm
Bodentier⁴ natural-history reference. [1]
LIFESPANNot established
No supported individual lifespan in the selected sources.
LIFESTYLEForest-dwelling
Beneath wood and leaves; rapid retreat into crevices. [1]

Adult size

12–16 mm in length in Bodentier⁴; natural-history profile reference, without a stated distinction between sexes. [1]

Lifespan

No individual lifespan established through a cohort in the selected sources.

Lifestyle

Mainly encountered beneath wood and leaves in forests; Bodentier⁴ describes immobility followed by rapid retreat into wood crevices as disturbance increases. [1]

Housing

NATURAL ENVIRONMENT

Cracked wood and litter — Documented forest environment; no complete captive protocol established. [1]

The selected sources define no minimum volume or complete captive protocol. Crevices and forest litter are observation contexts, not a sufficient recipe.

Care parameters

CAPTIVE CLIMATE

Not established — No validated husbandry range in the selected sources.

Humidity

Natural forest environment — Humidity not quantified; observations beneath wood and leaves. [1]

Shelters

Cracked wood and leaves in forests [1] Document their condition and moisture at the time of observation.

Climate

No numerical range adopted A continental distribution proves neither a need for cold nor universal resistance to high temperatures.

Feeding

DIET AND CALCIUM

No captive diet or specific mineral dosage is validated in the source collection. Presence in leaves does not measure their consumption. [1][2]

Scope of this profile

Natural-history or taxonomic sources distinguished from breeding accounts; captive limits explicit.

Keeping the name correctly

The catalogue brings several former names together under Trachelipus ratzeburgii. [2] Identification must nevertheless use the animal’s characters, not simply the label on a forest-origin group. When provenance is precise, retaining it later allows identification to be checked for consistency with regional literature.

Forest and shelters: concrete information

Bodentier⁴ reports almost exclusively forest occurrence in the context described, beneath wood and leaves, with few encounters on open ground. [1] During a field visit, record cover type and shelter position. A single observation under a stump does not, however, demonstrate that this tree species is the preferred food or only possible habitat.

Setup and substrate

The value of cracked wood is documented here as an escape shelter. [1] A captive project must additionally specify available water, air exchange and what happens to organic matter; these points are not tested by the two selected sources. This profile therefore prioritises observation in place. An existing culture must be described as strain experience, with its successes and losses.

Diet and calcium: do not fill gaps at random

No specific menu or mineral dosage is validated in the material consulted. Presence in leaves does not equal measured consumption of every leaf type. If a culture is already monitored, record materials offered and observed feeding, keeping a separate category for assumptions. Do not transfer a protein-feeding rhythm from another species sold alongside it.

Humidity and reproduction

Neither a target relative humidity, an incubation period nor an age at adulthood is adopted. The catalogue refers to older biological studies, but their mere presence in the bibliography does not permit their results to be invented. [2] Notes on young must specify context and identification confidence; apparent size alone does not date a birth.

Observing behaviour without provoking it

The immobility-then-escape sequence explains why a short inspection can give two different impressions. [1] Record whether wood was lifted before the photograph, then replace the shelter carefully. Repeated checks inside crevices make observations less comparable. Good records describe what changes in the shelter as much as what changes in the animals.

Checklist

  • Keep precise forest provenance.
  • Describe the wood shelter.
  • Separate observed facts from culture hypotheses.

Observations to record

  • Shelter, cover, exposure
  • Response to disturbance
  • Life stages and identification

The app provides individual animal records. Check which features are available for your animal in the released version.
