Blue spiders are among the most fascinating and visually striking arachnids in the world. Their vibrant blue coloration, often created through structural reflection rather than pigment, makes them highly unique. From deep cobalt tones to soft shimmering hues, these spiders captivate both researchers and hobbyists alike. In this list, you’ll discover 15 types of blue spiders, mainly tarantulas, each with distinct features, habitats, and behaviors that make them truly remarkable in the spider world.
1. Blue Tarantula
A “blue tarantula” is a general term used to describe tarantulas that display vivid blue coloration rather than a single scientifically recognized species. These spiders are admired for their striking, metallic blue shades that can range from soft bluish-gray to deep electric blue depending on species, lighting, and maturity. The coloration is often more intense in juveniles and may change slightly as the spider matures. Blue tarantulas are popular among arachnid enthusiasts due to their unique appearance, though they are generally better suited for experienced keepers because some species can be defensive or fast-moving.
Identification
- Color: Metallic or iridescent blue on legs, carapace, or entire body
- Size: Medium to large, typically 10–15 cm (4–6 inches) leg span
- Body Shape: Thick-bodied with dense hair covering the legs and abdomen
- Legs: Long and sturdy, often showing the most intense blue coloration
- Eyes: Eight small eyes grouped closely together
- Sexual Dimorphism: Females are larger, bulkier, and longer-lived than males
- Molting: Color may appear brighter after molting
Habitat
Blue tarantulas are usually found in warm, tropical, or subtropical environments across regions such as Asia, South America, and parts of Africa. Depending on the species, they may be arboreal (living in trees) or terrestrial (living on or below the ground). Arboreal types prefer to build silk retreats in tree hollows or branches, while terrestrial ones dig burrows in soil or hide under rocks and logs. These spiders thrive in humid conditions with stable temperatures, often requiring environments that mimic rainforest or savanna ecosystems. Proper humidity helps with molting and overall health.
Behavior
Blue tarantulas are typically nocturnal, becoming active at night to hunt for prey such as insects, small arthropods, and occasionally tiny vertebrates. They rely on speed, vibration sensing, and ambush tactics rather than webs to capture food. While many are shy and prefer retreat over confrontation, some species can be defensive if threatened. They may raise their front legs, display fangs, or flick urticating hairs (in New World species) as a warning. Old World species, however, lack these hairs and may rely more on biting as a defense mechanism.
Interesting Facts
The stunning blue coloration of these tarantulas is caused by structural coloration rather than pigment. Tiny nanostructures in their hairs reflect specific wavelengths of light, producing the blue effect. This means their color can appear to shift or shimmer depending on lighting and angle. Some blue tarantulas are among the fastest spiders, making them challenging to handle. Females can live for over 10–15 years, while males typically have much shorter lifespans. Their unique appearance and longevity make them highly valued in the exotic pet trade.
