You’re out hiking, maybe moving a log or a pile of leaves, and you see a flash of brilliant blue dart away. Your first thought is probably, "Wow, that’s stunning!" Quickly followed by, "Are blue-tailed lizards rare?" It’s a question that pops up all the time in online forums and backyard conversations. The short answer isn't a simple yes or no. It's a classic case of "it depends"—on where you are, which lizard you're actually looking at, and what you mean by "rare." Let's dig into the messy, fascinating details.
First, we need to get our lizard straight. The creature most people in North America call a "blue-tailed lizard" is almost certainly the five-lined skink (Plestiodon fasciatus). Juveniles of this species are famous for their vibrant, electric-blue tails. That color is breathtaking. But here’s the kicker—it doesn't last. As they grow into adults, that brilliant blue fades to a dull gray or brown, and the bold stripes become less pronounced. So when you ask, "Are blue-tailed lizards rare?" you might really be asking, "Are juvenile five-lined skinks rare?" which is a slightly different question. There are other skinks with blue tails around the world, but this guy is the poster child.
Quick ID Tip: A young five-lined skink has five light stripes running down its dark body and that signature bright blue tail. Adults are more uniformly brownish, sometimes with faint stripes and a gray tail. Males can develop a reddish-orange jaw during breeding season. Neat, right?
What Exactly is a "Blue-Tailed Lizard"?
Before we tackle rarity, let's clear that up first. "Blue-tailed lizard" isn't a formal scientific name. It's a common name thrown at several species, which causes a lot of confusion. If you're in the eastern United States or parts of Canada, you're likely seeing the five-lined skink. But in the American Southeast, you might find the broader-headed southeastern five-lined skink (Plestiodon inexpectatus). Out west, different skinks might have bluish tails. Even in Australia or Southeast Asia, there are lizards with blue tails. For this article, I'm focusing on the North American five-lined skink, because that's what most people searching this phrase are probably thinking of. I once spent an hour arguing with a friend who was convinced he saw a "blue-tailed dragon"—turned out to be a five-lined skink juvenile. The hype is real.
So, Are Blue-Tailed Lizards Rare? The Nuanced Answer
Okay, the moment you've been waiting for. Are blue-tailed lizards rare? Globally, the five-lined skink is listed as "Least Concern" on the IUCN Red List of Threatened Species. That sounds pretty common, and over its broad range, it is. But "Least Concern" at a global level doesn't tell the whole story. Rarity is local. In the heart of its range—like the deciduous forests of the Appalachian region—you can find them under plenty of logs. They're not rare there at all. But head to the northern edges of their territory, like parts of Ontario, Canada, and the story changes. There, they are considered a species of concern. Habitat loss pushes them into smaller, fragmented areas, making local populations much more vulnerable.
So, if you're in Tennessee and see one, it's a fairly common sight. If you're in a northern state or a province where development has chewed up the woods, you might have just spotted something a bit more special. The perception of rarity is also inflated because we mostly notice the stunning blue-tailed juveniles. Adults are duller and better at hiding, so we think we're seeing fewer of them than we actually are.
| Region | Conservation Status | Notes on "Rarity" |
|---|---|---|
| Core Range (e.g., Southeastern US) | Not Listed / Secure | Common in suitable forest habitat. Seeing a blue-tailed juvenile is a regular summer occurrence. |
| Northern Range Edge (e.g., Ontario, Canada) | Special Concern / Threatened | Local populations are scarce and fragmented. Habitat loss is a major threat. Sightings are more significant. |
| Urban/Suburban Areas | Varies Widely | Can be locally common in parks with woodpiles and old stone walls, or absent in highly manicured neighborhoods. |
The table above shows how the answer to "Are blue-tailed lizards rare?" shifts dramatically with your zip code. It's not a one-size-fits-all deal.
Factors That Make Them *Seem* or *Become* Rare
Several things affect how often you'll bump into one of these little blue streaks.
- Habitat Loss: This is the big one. Five-lined skinks love mature forests with plenty of fallen logs, loose bark, and leaf litter—perfect places to hunt insects and hide from predators. When we clear forests for development or even "clean up" a woodland too thoroughly, we destroy their homes. A fragmented forest can trap a population, making it harder for them to find mates and increasing inbreeding.
- The Pet Trade: This is a touchy subject. Those brilliant blue tails make them a target for the pet trade, even though they don't make the best pets (more on that later). Collection from the wild for pets can put pressure on local populations, especially if it's not regulated. It's a pet peeve of mine when people see a beautiful wild animal and their first instinct is to take it home. It's often a death sentence for the animal and hurts the wild population.
- Climate and Weather: Being cold-blooded, they're at the mercy of the environment. A late frost can wipe out a bunch of hatchlings. A particularly dry summer can reduce the insect prey they rely on.
- Predation: They're snack-sized for birds, snakes, raccoons, and even larger lizards. That bright blue tail? It might actually be a decoy. The theory is that a predator focuses on the wiggling, detachable blue tail while the skink itself makes a getaway. It's a brilliant survival trick, but it doesn't always work.
Important: Just because a species is common somewhere doesn't mean it's okay to take one from the wild. Many states and provinces have strict regulations protecting native reptiles. Always check local laws. The U.S. Fish and Wildlife Service and local herpetological societies are good resources for conservation laws.
How to Identify a Blue-Tailed Lizard (Five-Lined Skink)
Let's make sure you know what you're looking at. Misidentification is common. Here’s a quick breakdown of the five-lined skink versus some common look-alikes.
| Feature | Juvenile Five-Lined Skink | Adult Five-Lined Skink | Broad-Headed Skink (Similar Species) |
|---|---|---|---|
| Tail Color | Vibrant, electric blue | Gray or brown, may have hints of blue | Juveniles also have blue tails, but adults have a much larger, wedge-shaped head. |
| Body Stripes | Five distinct creamy or yellow stripes on black/brown | Stripes may fade, especially in males; body becomes more uniform bronze. | Stripes are similar but often less distinct. Look at the head size! |
| Size | Small (2-3 inches body + tail) | Up to 8.5 inches total length | Largest skink in the US; can exceed 12 inches. |
| Habitat | Moist forests, woodpiles, under debris | Same, but often found basking on sun-warmed surfaces. | Prefers wooded areas, often near water or in large, rotting stumps. |
If you see a lizard with a blue tail in the eastern US, you're almost certainly looking at a juvenile skink of some kind. The adult forms confuse people, leading them to think the blue-tailed ones have disappeared or are a different species. They just grew up.
Should You Keep a Blue-Tailed Lizard as a Pet?
I get it. That blue tail is mesmerizing. The thought of having that little jewel darting around a terrarium is tempting. But here's my honest, somewhat negative opinion: it's usually a bad idea. I've spoken to hobbyists who've tried, and many admit it's more challenging than they anticipated.
First, ethics and legality. In many areas, it's illegal to collect them from the wild without a permit. Wild-caught animals are often stressed, carry parasites, and struggle to adapt to captivity. They have complex needs tied to their natural habitat that are hard to replicate.
Second, care is tricky. They need a specific thermal gradient (warm basking spot, cooler areas), high humidity, and a diet of live insects like crickets and mealworms dusted with calcium. They're fast, skittish, and don't typically enjoy being handled. That beautiful blue tail can also autotomize (break off) if they're stressed or handled roughly, and while it regrows, it comes back in a duller color.
If you're absolutely passionate about keeping a skink, look for captive-bred reptiles from reputable breeders. Species like the blue-tongued skink (a different animal entirely) are often bred in captivity and make more adaptable pets. But for the wild five-lined skink? My strong advice is to admire them in your garden or on the trail. Let them be wild. Their role in controlling insect populations is more valuable than their brief stint in a tank where they often languish.
Bottom Line: The desire to own rare or beautiful wildlife is a major driver of their decline in some places. Appreciating them in their natural environment is the best way to ensure future generations can ask, "Are blue-tailed lizards rare?" and still have a chance to see one.
What to Do If You Find One (In Your Garden or On a Hike)
So you've found one! That's exciting. Here's how to be a good human.
- Observe, Don't Disturb. Watch from a respectful distance. Don't chase it or try to catch it. You'll stress it out and could cause it to drop its tail—a survival mechanism that costs it energy to regrow.
- Take a Photo for ID. Use zoom. A clear picture can help you confirm the species later. Note the location.
- Leave Its Home Intact. If you find it under a log or rock, gently replace the cover as you found it. That log is its apartment, pantry, and fortress all in one.
- Create Habitat (If You Want More). If you'd like to encourage them in your yard, build a rock pile or a stack of old logs in a sunny spot. Leave a section of your garden a little wild. Avoid pesticides, which kill their insect food.
- Report Significant Sightings. If you're in an area where they are considered rare or at-risk, consider reporting your sighting to a local university biology department, a herpetological society, or a citizen science app like iNaturalist. Your data can help conservationists.
It's that simple. Be a courteous guest in their home.
Common Questions About Blue-Tailed Lizards
Let's tackle some of the other things people are searching for when they wonder about these lizards.
Are blue-tailed lizards poisonous or dangerous?
No, they are completely harmless to humans. They are not venomous or poisonous. They have small teeth but are unlikely to bite unless severely provoked, and even then, it's more of a pinch. The bright blue tail might be a warning color to predators, but it's a bluff. They pose zero threat.
How long do they live?
In the wild, their life is tough. Many juveniles don't make it past their first year due to predation. If they survive, they can live 5 to 10 years. In captivity, with ideal care (which is hard to provide), they might reach the upper end of that range, but it's not guaranteed.
What do they eat?
They're insectivores. Their menu includes crickets, flies, spiders, beetles, caterpillars, and other small arthropods. They're great for natural pest control in your garden.
Why is the tail blue, and why does it fall off?
The brilliant blue is thought to serve two purposes: as a decoy for predators (focus on the tail, not the body) and possibly as a signal. The tail is made to detach. It contains a fracture plane between vertebrae. When grabbed, muscles contract to sever the tail, which continues to wiggle distractingly. The skink escapes and later regenerates a new, boneless tail made of cartilage. The new tail is often shorter and a different color.
Can I attract them to my yard?
Yes, if you're within their natural range. Provide cover (rock piles, log piles, a brush pile), a shallow water source (like a saucer), and minimize pesticide use. A sunny rock or board for basking is a nice bonus. Don't expect instant results—you're building a neighborhood, not a restaurant with a neon "Open" sign.
Are blue-tailed lizards rare in my specific state?
This is the key question that follows the general one. You need to check your state's wildlife agency website. For example, the Michigan DNR or the Ontario Ministry of Natural Resources will have species status reports. A quick search for "five-lined skink [Your State] protected status" will give you the local answer.
Final Thoughts
So, are blue-tailed lizards rare? I hope you see now that the question is a gateway to a much richer discussion about ecology, local conservation, and perception. The five-lined skink, in its dazzling juvenile form, is common in many places but faces real pressures in others. Its global status is secure, but local stories vary from "backyard buddy" to "species of concern."
The very fact that we're asking "Are blue-tailed lizards rare?" shows we care about what we're seeing. That curiosity is the first step toward stewardship. The best thing we can do is learn about the wildlife in our own communities, protect the habitats they rely on, and enjoy their beauty from a respectful distance. That way, the answer to "Are blue-tailed lizards rare?" won't slowly shift from "not really" to "unfortunately, yes" in more and more places.
Keep your eyes peeled next time you're in the woods. That flash of blue is a small, wonderful reminder of the wild world still buzzing and crawling all around us, even as we build over it. Let's make sure it stays that way.
