Jeweled Lacerta / Ocellated Lizard (Timon lepidus) Care Sheet
The Jeweled Lacerta, also widely known as the Ocellated Lizard (Timon lepidus), is a large, powerful and highly active European lacertid native primarily to the Iberian Peninsula and parts of southern France.
Adults are among the largest members of the family Lacertidae. Their vivid green colouration, dark reticulated pattern and distinctive blue ocelli along the sides make mature animals particularly striking.
Jeweled Lacertas are intelligent, alert and highly food-motivated lizards. Captive-bred individuals can become surprisingly confident around their keepers, although they are generally better regarded as active observation animals rather than reptiles that require frequent handling.
Successful care centres on a large enclosure, intense basking heat, strong UVB, deep substrate, plentiful cover, opportunities to dig and climb, and a varied diet based primarily on appropriately sized invertebrates.

Natural Distribution
Timon lepidus occurs primarily across Spain, Portugal and southern France.
Its range includes a variety of Mediterranean and temperate environments, and wild populations experience considerable seasonal changes in temperature and rainfall.
Natural Habitat
Jeweled Lacertas inhabit:
- Mediterranean scrub
- Dry woodland
- Rocky hillsides
- Open forest
- Grassland
- Agricultural margins
- Stone walls
- Areas with dense ground vegetation
They make extensive use of burrows, rock crevices, dense vegetation and fallen timber.
Captive housing should provide similar opportunities for concealment and exploration.
Appearance
Adults can be spectacularly coloured.
Typical features include:
- Green body colour
- Black or dark reticulated pattern
- Blue spots or ocelli along the sides
- Strong limbs
- Long tail
- Large robust head
Juveniles are often less intensely green and display a strongly spotted pattern.
Colour generally becomes more impressive as animals mature.
Adult Size
Adults commonly reach approximately:
20–28 inches total length
Much of this consists of the tail.
Males generally develop larger heads, heavier jowls and more robust bodies than females.
Behaviour
Jeweled Lacertas are active and intelligent.
Normal behaviour includes:
- Basking
- Digging
- Hunting
- Exploring
- Climbing
- Moving between cover
- Investigating changes in their surroundings
They should not be maintained in small, barren accommodation.
Temperament
Young animals can be extremely nervous and fast.
When frightened they may flee, hide, tail-whip or bite if restrained.
Captive-bred individuals often become considerably calmer with patient husbandry.
Forced handling should be avoided.
Handling
Allow the animal to become accustomed to its keeper gradually.
Useful approaches include:
- Hand-feeding with long tongs
- Working calmly inside the enclosure
- Allowing the lizard to approach voluntarily
- Keeping handling sessions short
Never grab a Jeweled Lacerta by the tail.
Tail Autotomy
Like many lacertids, Jeweled Lacertas can shed their tail as a defence mechanism.
The tail may regenerate, but the replacement will not be identical to the original.
Avoid grabbing the tail or unnecessarily chasing and restraining the animal.
Enclosure Size
For an adult:
48" × 24" × 24"
should be regarded as a practical minimum.
Large adults, particularly males, are better provided with:
60" × 24" × 24"
or larger.
Additional floor area is highly beneficial.
Why Space Matters
Jeweled Lacertas are active hunters.
A larger enclosure allows:
- Exercise
- Exploration
- Proper thermoregulation
- Multiple hides
- Deep substrate
- Natural hunting behaviour
Their enclosure should provide genuine environmental choice.
Substrate
A deep naturalistic substrate is strongly recommended.
Suitable mixtures can contain:
- Organic topsoil
- Play sand
- Clay-based substrate
- Excavator-type material
- Suitable Mediterranean reptile substrate
The substrate should allow digging and the formation of shallow burrows.
Substrate Depth
Provide approximately:
4–6 inches minimum
with deeper areas where possible.
Heavy furnishings must be positioned securely so they cannot collapse onto a digging animal.
Hides
Provide several secure retreats.
At minimum include:
- Warm hide
- Cool hide
- Humid retreat
Additional cork tubes, rock-style caves, buried hides and dense vegetation are beneficial.
Climbing
Although primarily terrestrial, Jeweled Lacertas climb readily.
Provide cork bark, large branches, rocks and platforms.
All heavy structures must be securely supported.
Basking Temperature
Jeweled Lacertas require access to intense basking heat.
Provide a basking surface around:
40–45°C
This should be a localised surface temperature rather than the general enclosure temperature.
Warm Ambient Temperature
The warmer region can generally remain around:
26–30°C
Cool Area
Maintain a cooler retreat around:
20–24°C
The animal must always be able to escape the basking heat completely.
Night Temperature
Night temperatures can fall to approximately:
16–21°C
Night heating is generally unnecessary unless the room becomes excessively cold.
Heating
A bright overhead basking lamp is ideal.
Halogen basking lamps provide heat, visible light and a defined basking area.
The basking zone should be large enough to warm the animal’s entire body.
UVB
UVB is essential for Jeweled Lacertas.
Use an appropriate high-quality linear UVB system.
The basking area should provide suitable UV exposure while allowing the animal to retreat into partial shade, dense cover and complete hides.
UVB provision must take into account lamp strength, distance, mesh obstruction and manufacturer recommendations.
UVB and Calcium
UVB allows the lizard to synthesise vitamin D3, which is essential for effective calcium metabolism.
Inadequate UVB and poor dietary calcium can contribute to metabolic bone disease.
Possible signs include:
- Soft or distorted jaw
- Tremors
- Weakness
- Swollen limbs
- Difficulty walking
- Spinal deformity
- Fractures
Lighting
Jeweled Lacertas are strongly diurnal.
Provide bright daytime illumination.
Approximately 12–14 hours of daylight during summer, with a shorter winter photoperiod, can be used.
Humidity
General humidity around:
40–60%
works well for most setups.
Humidity should not be completely uniform.
Provide a humid retreat containing slightly damp substrate such as soil, sphagnum moss or coco fibre.
Ventilation
Good ventilation is essential.
Warm, stagnant and excessively humid conditions can contribute to respiratory problems, skin problems, mould and bacterial growth.
Water
Fresh drinking water must always be available.
Provide a stable shallow bowl and replace contaminated water immediately.
Diet in the Wild
Jeweled Lacertas are opportunistic predators.
Natural foods include:
- Beetles
- Grasshoppers
- Crickets
- Spiders
- Caterpillars
- Snails
- Other invertebrates
Large adults may occasionally consume small vertebrates, eggs and some plant material.
Invertebrates should remain the foundation of the captive diet.
Captive Diet
Provide a varied selection of appropriately sized feeder invertebrates.
Suitable options include:
- Crickets
- Locusts
- Dubia roaches
- Other suitable roaches
- Mealworms
- Morio/superworms
- Silkworms
- Calciworms / black soldier fly larvae
- Snails from safe captive sources
Variety is important.
Gut Loading
Feeder insects should be well gut-loaded before use.
Feed insects a nutritious diet containing appropriate greens, vegetables and quality gut-loading foods.
Calcium Supplementation
Invertebrate prey should be appropriately supplemented with calcium.
The supplementation programme should account for:
- Age
- Reproductive status
- UVB provision
- Diet
- Feeder species
Juveniles and breeding females have particularly significant calcium requirements.
Fruit
Some adults may accept small quantities of fruit.
Fruit should be regarded as occasional dietary variety rather than a staple food.
Rodents
Large adults are capable of eating small rodents.
However, rodents are not required as a routine staple diet.
Frequent rodent feeding can contribute to excessive calorie intake and obesity.
Juvenile Feeding
Growing juveniles can generally be fed:
Daily or 5–6 days per week
using appropriately sized insects.
Adult Feeding
Adults can generally be fed approximately:
3–4 times per week
depending on prey size, activity, season and body condition.
Obesity
Jeweled Lacertas are enthusiastic feeders and can become overweight.
Monitor the abdomen, tail base, jowls and overall body condition.
Do not confuse obesity with healthy robust condition.
Food Enrichment
Food can provide excellent enrichment.
Try:
- Scattering insects
- Allowing controlled hunting
- Hiding feeders in safe areas
- Tong-feeding selected items
This encourages natural foraging behaviour.
Social Housing
Individual housing is the safest general recommendation.
Adults can be territorial, competitive and aggressive, particularly between males.
Adult males should generally not be housed together.
Sexing
Adult males generally develop:
- Larger heads
- More pronounced jowls
- Broader bodies
- More visible femoral pores
Females generally have smaller, more streamlined heads.
Sexing juveniles can be more difficult.
Seasonal Cycle
Wild Jeweled Lacertas experience strong seasonal changes.
Winter activity may decline substantially.
Experienced breeders sometimes reproduce seasonal cooling to encourage natural reproductive cycles.
Brumation
Healthy mature animals may undergo controlled winter cooling.
Only animals that are healthy, properly hydrated, in appropriate body condition and free from undigested food should be deliberately cooled.
Brumation should only be attempted when the keeper understands the process.
Breeding
Breeding generally follows winter cooling and spring warming.
Males may become highly active and territorial during the breeding season.
Females require excellent nutrition and calcium reserves.
Egg Laying
Jeweled Lacertas are oviparous.
Females require access to deep suitable laying substrate.
A nesting area should allow the female to excavate naturally.
Clutch Size
Females may produce approximately:
5–20 eggs
depending on size, age and condition.
More than one clutch may sometimes be produced during a breeding season.
Incubation
Eggs are commonly incubated at approximately:
26–29°C
under stable humid conditions.
Incubation duration varies with temperature.
Eggs should not be rotated after laying.
Hatchlings
Hatchlings are small, fast and active.
Provide:
- Secure housing
- Multiple tiny hides
- Suitable UVB
- Basking heat
- Shallow water
- Small feeder insects
- Appropriate supplementation
Juvenile escape prevention is essential.
Quarantine
All newly acquired reptiles should undergo quarantine.
A minimum of approximately:
90 days
is a sensible starting point.
Monitor feeding, weight, faeces, shedding, respiration, skin and external parasites.
Parasites
Wild-caught or poorly sourced animals may carry significant parasite burdens.
Captive-bred animals should be strongly preferred.
Veterinary faecal testing may be appropriate for animals of uncertain history.
Shedding
Jeweled Lacertas shed their skin in patches rather than as a single complete skin.
During shedding, monitor areas around the toes, tail and limbs.
Persistent retained skin can restrict circulation.
Signs of Good Health
A healthy Jeweled Lacerta should generally display:
- Clear bright eyes
- Strong limbs
- Firm jaw
- Alert behaviour
- Regular basking
- Strong feeding response
- Smooth coordinated movement
- Good muscle tone
- Normal faeces
Warning Signs
Seek veterinary advice for:
- Persistent food refusal
- Unexplained weight loss
- Weakness
- Tremors
- Swollen limbs
- Soft jaw
- Abnormal gait
- Respiratory symptoms
- Persistent diarrhoea
- Skin lesions
- Abnormal swelling
- Prolapse
- Severe retained shed
Common Husbandry Mistakes
Enclosure Too Small
These are large, active lacertids.
Weak UVB
Appropriate UVB provision is fundamental.
Basking Temperature Too Low
Jeweled Lacertas require access to a genuinely hot basking surface.
No Cool Retreat
A hot basking area must be balanced by a substantially cooler zone.
Shallow Substrate
Digging is an important natural behaviour.
Poor Diet Variety
Do not rely on one feeder insect.
No Gut Loading
Poorly nourished feeder insects provide poor nutrition.
Excessive Rodent Feeding
Rodents are unnecessary as a staple and can contribute to obesity.
Forced Handling
Building confidence gradually is preferable.
Grabbing the Tail
Tail autotomy can occur.
Housing Adult Males Together
Serious aggression may result.
Captive-Bred Versus Wild-Caught
Captive-bred animals should be strongly preferred.
Advantages include:
- Known origin
- Reduced parasite risk
- Better acclimation
- Greater likelihood of becoming confident
- Reduced pressure on wild populations
