At a glance: A lined gecko diet runs on live insects sized to the animal’s head width. Dust most feedings with calcium and add a multivitamin about once a week. Feed hatchlings daily and older animals at least every other day, the Merck Veterinary Manual’s general rule for lizards, with fresh water or nightly misting for drinking.

The white lined gecko (Gekko vittatus), also called the skunk gecko, is a nocturnal, arboreal insectivore. It comes from the forests and coastal vegetation of New Guinea, the Solomon Islands, and nearby Indonesian islands. A lined gecko diet has one job: replace the nighttime insect activity this species would find in that humid tropical range.
This genus does not rely on fruit or nectar the way a day gecko does. Every feeding decision below follows from that basic biology.
What a White Lined Gecko Eats
Gekko vittatus is an insectivore first. No zoo or veterinary source documents fruit or nectar as part of its diet, so it does not need fruit purees, nectar mixes, or powdered complete gecko diets to thrive. Its feeding strike is built for chasing and grabbing moving prey, not for lapping soft food off a dish.
The best documented relative is the tokay gecko (Gekko gecko). The Smithsonian’s National Zoo lists its wild prey as moths, locusts, grasshoppers, beetles, cockroaches, termites, crickets, mosquitoes and spiders, with small rats, mice and snakes taken by big adults. The zoo itself feeds tokays crickets, cockroaches and mealworms.
Animal Diversity Web adds springtails, pink mice and locusts to the tokay list. Those are tokay figures, not white lined gecko data, but the two species share a genus and a night hunting habit. Expect the same broad insect menu, scaled down to a smaller mouth.
A rotating stock of feeder insects gives the closest match to natural variety. Crickets remain the base feeder for most keepers. They are easy to gut load and easy to size consistently for a growing animal.
Dubia roaches are a strong addition or alternative to crickets. They rarely bite or hide in the enclosure overnight. Black soldier fly larvae, small mealworms, and butterworms round out a healthy rotation.
- Crickets: the everyday staple, gut loaded before every feeding.
- Dubia roaches: quiet, slow, and less prone to hiding uneaten.
- Black soldier fly larvae: a common rotation item for adults.
- Small mealworms: a rotation item, not a sole diet.
- Waxworms and butterworms: occasional, fatty treats rather than a regular feeder.
- Silkworms and hornworms: high moisture, well accepted, good for hydration.
Fruit flies and pinhead crickets matter most for hatchlings. Their mouths cannot yet manage adult sized prey. A common keeper standard is to size every feeder no wider than the space between the animal’s eyes, which lowers the risk of regurgitation.
Feeding Schedule by Age
A lined gecko feeding schedule tracks age and growth rather than one fixed rule. Hatchlings and young juveniles grow fast and burn more energy for their size. They need food more often than a settled adult.
| Life stage | Feeding frequency | Typical prey size |
|---|---|---|
| Hatchling (0 to 3 months) | Daily, small portions | Fruit flies, pinhead crickets |
| Juvenile (3 to 12 months) | Every other day | Small to medium crickets, small roach nymphs |
| Subadult | Every other day | Medium crickets, roach nymphs |
| Adult | Every other day, smaller portions | Adult crickets, medium to large roaches |
| Gravid female | Daily to every other day, extra calcium | Same as adult, larger portion |
The frequencies follow the Merck Veterinary Manual’s general lizard rule: feed daily for juveniles and small species, or at least every other day. The prey sizes are a common keeper standard, not a number published for Gekko vittatus specifically. Adjust up or down based on the individual animal’s body condition.
Every other day feeding can still overfeed a gecko in a small enclosure. Merck ties reptile obesity and fatty liver to restricted exercise plus excess calories, and advises trimming intake slowly over months. Cut portion size before you cut frequency.
A gecko losing tail thickness or looking sunken near the pelvis needs feeding more often. One carrying visible fat pads at the tail base needs less. Feed in the evening, close to when the lights go off, since this species hunts in low light.
Offer only what the animal will finish in about 15 to 20 minutes. Then remove any leftover insects. Uneaten feeders can stress the gecko or nibble on it while it rests.
How Much to Feed
Portion size scales with the gecko’s own body, not a fixed insect count. A workable rule is to offer as many appropriately sized insects as the animal will actively hunt in one sitting. That usually means three to six crickets or roach nymphs per feeding for an adult, fewer for a juvenile, a keeper standard that the general what do lizards eat guide explains for insectivores.
Watch the belly rather than the calendar. A light rounding after a meal is normal. A visibly swollen or bloated abdomen signals overfeeding or a feeder that was too large to digest easily.
Free feeding roaches or crickets left loose between scheduled feedings is not recommended for this species. Uneaten insects can hide in cork bark or foliage, breed, or nibble on a resting gecko. It also makes it harder to track how well the animal is actually eating.
Calcium and Vitamin Supplements
Feeder insects on their own carry the wrong calcium to phosphorus balance for a captive reptile. Every insectivorous gecko needs supplementation layered on top of feeding. The Merck Veterinary Manual’s reptile husbandry guidance is explicit on this point.
It calls for feeding insects a nutritionally complete, calcium rich diet first. Then dust them with a calcium supplement immediately before offering them to the gecko. This is required to prevent nutritional secondary hyperparathyroidism, the metabolic bone disease that follows chronic calcium or vitamin D3 shortfalls in captive reptiles.
Merck’s nutrition chapters put numbers on it. Insects hold only 0.03 to 0.3 percent calcium against 0.8 to 0.9 percent phosphorus, while the diet ratio should be at least 1:1 and preferably 2:1. Gut loading on a 12 percent calcium diet for 3 days lifts insect calcium to about 0.8 to 0.9 percent and the ratio to roughly 1.2:1.
Merck calls metabolic bone disease the most common bone disease in reptile practice. Early signs are lethargy, poor appetite and trouble walking; later come a swollen or soft jaw, twitching and fractures. Insectivorous lizards are also prone to vitamin A deficiency, which shows as poor growth, appetite loss, mouth inflammation and swollen eyelids.
In practice, dust feeders with a plain calcium powder at most feedings. Alternate with a calcium plus D3 formula once or twice a week if the enclosure lacks UVB lighting. Add a reptile multivitamin roughly once a week to cover other micronutrients.
A dish of plain calcium powder left in the enclosure lets the gecko self dose between feedings. Some keepers also feed a gut loading supplement to the insects a day or two before offering them, so the extra nutrients pass through to the gecko.
- Plain calcium without D3: use at most feedings if UVB lighting is provided.
- Calcium with D3: use once or twice weekly, more often without UVB.
- Reptile multivitamin: use about once weekly, not every feeding, to cover vitamin A.
Dusting a fast, food driven gecko works best with the right tools. Many keepers shake insects inside a small bag or cup rather than coating them by hand. A pair of soft tip feeding tongs then keeps fingers safely away from a startled bite.
Does It Eat Fruit or Powdered Complete Diets
Gekko vittatus is not a fruit or nectar feeder the way Phelsuma day geckos are. It should not be treated as one. The documented diet of its genus, from the tokay accounts above, is insects and other small animals taken at night.
A commercial powdered complete diet made for fruit eating geckos is not a substitute for live insect prey in this species. Some keepers report white lined geckos licking soft fruit or a complete diet paste. This is a keeper report, not a documented nutritional need, so treat it as enrichment that never replaces the insect plan.
The same rule applies to its Vietnamese relative, the golden gecko, another nocturnal Gekko fed on insects. Neither species has a published feeding study, which is why both pages lean on Merck’s general lizard guidance.
Water and Hydration
A shallow water dish should stay available at all times, refreshed daily. Many nocturnal arboreal geckos still drink more readily from droplets than from standing water. Misting the enclosure once or twice a day, timed so droplets form on leaves and cork bark, gives a natural way to drink.
Merck notes that reptiles which will not drink from a bowl are watered with timer controlled sprinklers or drip systems. A drip system or automated mister does the same job with less daily effort, and it helps hold the higher humidity this species needs between feedings. Watch for sunken eyes, loose skin that does not spring back when gently pinched, and reduced appetite, all signs of dehydration rather than a feeding problem.
Feeding a Fast, Nervous Species
Gekko vittatus is quicker and more reactive than many popular pet geckos. It can bolt, drop its tail, or refuse food if feeding feels threatening. Tong feeding lets a keeper present insects without reaching directly into the animal’s space.
Tongs also let a keeper confirm exactly how much a gecko has eaten. That detail matters for tracking body condition over time. A newly acquired or recently rehoused gecko may refuse food for the first several days while it settles in.
Keep offering appropriately sized insects on the normal schedule during this period. Keep handling to a minimum as well. Only get concerned if refusal stretches past two to three weeks alongside visible weight loss.
A gecko that strikes readily at moving prey but backs away from a still, hand held insect is behaving normally. The strike response depends on movement, not on trust in the keeper. Feeding at the same time each evening, in the same enclosure spot, helps a nervous animal settle into the routine faster.
Frequently Asked Questions
What is the best staple feeder for a white lined gecko?
Crickets and dubia roaches both work well as the base of a lined gecko diet. Rotating between the two keeps the gecko interested and avoids it refusing a single feeder type. Roaches are slower and hide less once released into the enclosure.
Do white lined geckos need UVB lighting for their diet to work?
UVB is not strictly required if calcium with D3 is dusted onto feeders consistently. Low level UVB still reduces reliance on dietary D3 and is considered good general practice for many reptiles. For a nocturnal species like this one, low intensity UVB near a daytime hide is optional rather than mandatory.
Can a white lined gecko eat mealworms every day?
Mealworms can join the rotation but should not be the sole or daily feeder. Their harder exoskeleton is less digestible in large amounts than softer bodied roaches or crickets. Use them as one option among several rather than the default staple.
Why is my white lined gecko refusing to eat?
Recent rehoming, a temperature or humidity drop, shedding, or an oversized feeder are the most common causes of temporary refusal. Persistent refusal past two to three weeks with visible weight loss calls for a reptile veterinarian visit. That rules out illness or internal parasites.
How big should feeder insects be for this species?
A dependable keeper standard keeps every feeder no wider than the space between the gecko’s eyes. Scale that up gradually as the animal grows from hatchling to adult. Oversized prey raises the risk of regurgitation rather than adding better nutrition.
Is a powdered complete gecko diet enough on its own?
No. Complete powdered diets are formulated for fruit and nectar feeding geckos like Phelsuma. Gekko vittatus needs live insect prey as the core of its diet, with calcium and vitamin dusting layered on top rather than a powder replacing insects outright.
For the rest of this species’ care beyond feeding, see the white lined gecko care guide.
