| Juvenile Stage Ends | 10 months |
| Senior Age Threshold | 1 years |
| Exercise Needs | Low - nocturnal climber; moderate activity at night |
|---|---|
| Grooming | None - maintain substrate; replace fruit daily; mist for humidity |
| Annual Exam Focus | Triple horn integrity (males), elytra sheen, leg grip, mite check, weight monitoring |
| Routine Care | Maintain 75-82°F; 70-80% humidity; fresh fruit/jelly daily; mist substrate; spot clean weekly |
| Condition | Onset Stage | Risk | Hereditary | Screening |
|---|---|---|---|---|
| Mite Infestation | adult | high | No | N/A |
| Dehydration | adult | medium | No | N/A |
| Bacterial Infection | adult | medium | No | N/A |
| Fungal Infection (larvae) | larval | medium | No | N/A |
| Horn/Leg Damage | adult | medium | No | N/A |
| Wing Deformity (from pupation) | adult | low | No | N/A |
| Risk Level | Low |
|---|---|
| Ideal BCS | 3/9 |
| Visual Cues | Abdomen contained within elytra; not bulging; metallic sheen indicates good health |
| Daily Activity | 3 minutes |
| Caloric Notes | Beetle jelly and fresh fruit daily; larvae need protein-enriched flake soil |
| Litter Size | 20–60 |
|---|---|
| Dystocia Risk | Low |
| CHIC Required Tests | N/A |
| Recommended DNA Tests | N/A |
| Neonatal Weight | 1–2 g |
|---|---|
| Growth Notes | Larval stage 8-14 months; pupation 1-2 months; larvae reach 60-80g; adult stage 3-8 months only |
| Vaccine/Health Schedule | No vaccines; sterile substrate critical for larvae; temperature consistency |
| Temperature | 24-28°C (75-82°F); tropical warmth required |
|---|---|
| Humidity | 70-80%; moist substrate; daily misting; ventilation important |
| UVB Requirement | Not required; nocturnal species; ambient light cycle |
| Diet | Adults: beetle jelly, banana, mango, apple; Larvae: fermented hardwood flake soil with added protein |
| Common Issues | Mites, bacterial infections, dehydration, horn damage from fighting, fungal issues in larvae |
| Anxiety Proneness | Very Low |
|---|---|
| Top Triggers | Bright lights, handling during day, dry conditions, male-male proximity, vibrations |
| Separation Anxiety Risk | None |
| Calming Interventions | Dark hides, moist substrate, consistent warmth, separation from other males |
| Enrichment Needs | Climbing branches, cork bark, deep substrate, varied fruit, leaf litter layer |
| Cognitive Dysfunction Risk | Very Low |
| Sociability Score | 2/10 |
| Locomotion | Nocturnal climbing, powerful flight, burrowing; males engage in horn combat |
|---|---|
| Social | Males highly aggressive toward other males; horn wrestling for territory; tolerant of females |
| Comfort | Burrowed in substrate or resting under bark during day; feeding at night; metallic sheen visible |
| Stress/Displacement | Stridulation, defensive posture with horns raised, refusing food, excessive daytime activity |
| Breed-Specific | Three-horned rhinoceros beetle; metallic green-black coloration; powerful flier; aggressive males; popular in Asian beetle keeping |
| Types | Stridulation (squeaking) when disturbed or handled |
|---|---|
| Frequency Range | 1,000-4,000 Hz |
| Tendency | Low |
| Primary Modality | Chemical (pheromones); tactile; stridulation defensive |
| Tail/Body Signals | No tail; triple horn structure unique identifier; elytra metallic sheen indicates health |
| Top Problems | Male-male aggression (horn fighting), powerful escape flights, substrate excavation |
|---|---|
| Medical Etiology | Lethargy, loss of metallic sheen, mite clusters, inability to right self when flipped |
| Fear/Anxiety Etiology | Stridulation, tucking legs, horn-down defensive posture, playing dead |
| Frustration Etiology | Repeated flight attempts, horn pushing against walls, nocturnal pacing |
| Learned Behavior | Associates fruit placement with food; learns enclosure boundaries; basic spatial memory |
| Cognitive Dysfunction | Very limited; instinct-driven; combat behavior is innate |
| AI-Trainable Signals | Metallic sheen intensity (health), horn posture (aggression level), activity timing, grip strength |
|---|---|
| Context-Dependent Vocalizations | Horn raising can be defensive OR combat-ready - presence of rival male differentiates |
| Interspecies Communication | Strong grip can pinch; impressive display; tolerates brief handling; horn grip reflexive |
