Hawaii’s lava fields, rainforest trails, and backyard gardens are full of small reptiles darting across walls and tree branches, yet not one of them evolved on the islands. Search for the types of lizards in Hawaii and you’ll turn up geckos clinging to porch lights, anoles flashing color in hibiscus hedges, and a chameleon that traveled here from East Africa decades ago. The Hawaiian language even reflects how few lizards existed before contact with the outside world:
The Hawaiian language has only one word for lizard: mo’o. Even though there were only a few species of lizard in Hawaii before Western contact, Hawaiian legends are filled with them. Every lizard living in the state today arrived after that first contact, whether by cargo ship, potted plant, or the exotic pet trade. The last surviving indigenous lizard species, the Hawaiian skink (Emoia impar), was declared extinct in 2013, and the only native reptiles left in the islands are the sea turtles found in Hawaiian waters and the yellow-bellied sea snake. Readers curious about that side of the story can check this guide to snake species found across Hawaii for more on the state’s other reptile arrivals.
This guide profiles five of the archipelago’s most recognizable lizards: the mourning gecko, orange-spotted day gecko, Jackson’s chameleon, brown anole, and common house gecko. Each one tells a different story about how species hitchhike across oceans and settle into new homes.
| Lizard | Native Region | Arrived in Hawaii | Typical Habitat |
|---|---|---|---|
| Mourning Gecko | Tropical Asia and the Pacific | Historic, via cargo ships | Coastal forests, buildings |
| Orange-spotted Day Gecko | Madagascar region (Phelsuma family) | 20th century, exotic pet trade | Palm trees, gardens, porches |
| Jackson’s Chameleon | Kenya, East Africa | 1972 | Cool upland forests and gardens |
| Brown Anole | Cuba and the Bahamas | Accidental, via imported plants | Gardens, low trees, walls |
| Common House Gecko | Southeast Asia and the Pacific | Historic, via shipping | Homes, walls, exterior lights |
1. Mourning Gecko
The mourning gecko (Lepidodactylus lugubris) is easy to overlook, mostly because it is smaller than a AA battery and does most of its business after dark. It is primarily nocturnal, though it is occasionally encountered exposed but near cover during the day. Its cryptic tan-and-brown coloring lets it disappear against bark almost instantly.
What makes this gecko genuinely strange is how it reproduces. Lepidodactylus lugubris, also called the common smooth-scaled gecko, is a female-only species. This small, nocturnal gecko feeds on small insects and flower nectar, and it is notable because it is parthenogenic, with no remaining males ever found. A single female can start an entirely new population without ever mating, which explains how the species spread across so many Pacific islands.
Mourning geckos in Hawaii prefer natural and rural places, favoring mangrove thickets and open rocks with regular sunlight. They hide in plain sight by clinging to tree branches and trunks, then hunt insects once night falls. Their eggs add another layer to the survival story: eggs belonging to this species have been found to be tolerant of saltwater, meaning they could likely survive drifting reasonable distances if washed out to sea.
Pro Tip: Check porch lights and mangrove-lined trails after sunset. Mourning geckos are most active at night and tend to freeze rather than flee when a flashlight beam passes over them.
The species originally comes from coastal Southeast Asia, a region shared with other well-documented lizard communities profiled in this guide to lizard species found in Malaysia. Because they thrive in captivity without any special breeding setup, mourning geckos have also become a low-maintenance option among popular pet reptiles kept by hobbyists nationwide.
2. Orange-spotted Day Gecko
The orange-spotted day gecko trades the mourning gecko’s secrecy for a much flashier, sun-loving lifestyle spent perched in palm fronds and porch eaves. It is a brilliant example of the bright colors common in tropical lizard species: a green and orange gecko with large toe pads, a blunt, square-shaped nose, round docile eyes, and a light blue cape-like wash around the shoulders. Adults reach a maximum length of about 7 inches.
On Oahu, where the species has settled in, its diet leans heavily on plant sugars rather than pure predation. They sip nectar from flowers and eat fruit, and suburban neighborhoods pose no problem since they benefit from higher insect pest populations there. Tall palm trees rank among their favorite hangout spots. The species is also known to feed on the juices of overly ripe fruit, which is part of why gardens with fruit trees tend to attract them.
The orange-spotted day gecko belongs to the genus Phelsuma, a group centered on Madagascar and its surrounding islands. Its greener, gold-flecked cousin has followed a similar path elsewhere: the gold dust day gecko is one of the most colorful lizards found in Hawaii, native to Madagascar, where it has since thrived in warm, tropical conditions after introduction. Related Phelsuma species have made similar moves into warm coastal pockets of the mainland United States, a pattern also visible among the lizard species established in California.
3. Jackson’s Chameleon
Jackson’s chameleon (Trioceros jacksonii) is arguably the most unusual lizard on this list, and it looks the part. It has a 360-degree field of vision, can change the color of its skin at will, and has a tongue one and a half times the length of its body. Its toes are especially adapted into a pincer-like shape for grabbing tree branches, and males carry three rhino-like horns on the nose and forehead, earning the nickname Three-horned Chameleon.
Despite a reputation for moving slowly, this chameleon holds its ground. It is very territorial despite its slow-moving reputation, and males and females meet only to mate before going their separate ways. That solitary streak makes sightings feel more like a discovery than a given, even in areas where the species is established.
Jackson’s chameleon was introduced to Hawaii from Kenya in 1972, and it has since spread to the four main islands of Hawaii, Kauai, Oahu, and Maui. It was originally released on a small plot of land in Kaneohe, Oahu, and soon made its way to most all islands in the Hawaiian chain. That single release point, multiplied across five decades, shows how quickly one introduced population can spread through a favorable climate.
Important Note: Hawaii restricts the import and possession of most reptile species, chameleons included, to limit further ecological disruption. Rules can change, so verify current regulations with Hawaii’s Department of Agriculture before considering any reptile as a pet.
Africa hosts a much wider chameleon lineage than most visitors realize, a diversity explored further in this look at lizard species native to South Africa. Within the exotic pet trade, chameleons remain a demanding but popular choice among the reptile species people keep at home, despite their reputation for needing precise humidity and temperature control.
4. Brown Anole
The brown anole (Anolis sagrei) is probably the lizard most visitors notice first, since it treats gardens, fences, and low walls as its own personal stage. It is one of the most commonly found lizards in Hawaii’s gardens, and like chameleons, anoles can change color, though brown anoles can only shift between shades of brown. When they feel threatened or are trying to attract a mate, they flash a bright pop of orange and red with their dewlap.
That dewlap display is more than decoration. Males use it to warn off rivals and signal to females, often paired with a series of quick push-ups on a fence post or tree branch. Brown anoles are not native to Hawaii, but they have inhabited the islands for decades, having first lived in Cuba before accidentally arriving in soil packed around imported plants.
Brown anoles have gone on to become one of the most widespread lizards across the American South, a story that runs parallel to their Hawaii population and is covered in more detail in this guide to lizard species found in Florida. Their Caribbean relatives make up a large share of the reptile life documented in this overview of lizard species native to Jamaica.
Conservation groups in Hawaii tend to view every new anole sighting with some caution. As one Hawaii-based wildlife organization put it, it is now more imperative than ever to refrain from introducing any other reptile species to the islands and to advocate for preserving what remains of the current species population.
5. Common House Gecko
The common house gecko (Hemidactylus frenatus) is the lizard most likely to share a wall with a Hawaii resident, often within arm’s reach of a porch light. It is native to Southeast Asia and the Pacific Islands, with populations spanning Bali, Indonesia, Australia, and even Madagascar. That wide native range hints at how well the species travels, and it has clearly done the same across the Hawaiian chain.
Its plain gray-brown coloring undersells how useful it is to have around. This gecko is a skilled insect hunter, feeding on moths, mosquitoes, and small beetles, which makes it genuinely beneficial to humans as a natural pest controller. Its ability to reproduce quickly keeps its population stable even where it competes with other lizard species.
Although plain in appearance compared to the colorful day geckos, the common house gecko plays an important ecological role. Its nocturnal habits, quiet chirps, and habit of lurking around lights make it a familiar presence in Hawaiian households. That chirping is often the first clue that one has moved in behind a picture frame or curtain rod.
Pro Tip: A short chirping or clicking sound near a window at night almost always means a common house gecko, not an insect. Leave it be; it is actively working through the moths and mosquitoes drawn to indoor lighting.
The species has also gained a strong foothold in the mainland United States, appearing in warm, humid regions documented in this guide to lizard species found in Texas. Its resilience and adaptability echo a broader pattern seen across many introduced gecko populations worldwide.
None of the five lizards covered here are native to Hawaii, and that fact says as much about the islands’ isolation as it does about the reptiles themselves. Every gecko, anole, and chameleon now calling Hawaii home arrived through human activity, whether by accident in a shipment of soil or on purpose through the pet trade decades ago. Anyone exploring the islands’ other introduced wildlife might also enjoy this companion guide to frog species found across Hawaii, which follows a strikingly similar pattern of arrival and adaptation.
