Huntsman Spider, Giant Crab Spider, Banana Spider
Heteropoda venatoria (most likely genus Heteropoda)
Sparassidae (Huntsman Spiders), Order Araneae. Key family characteristics include a crab-like posture with legs extending sideways and high mobility.
Physical Description
Flattened body profile designed for slipping into narrow crevices, large oval abdomen, robust cephalothorax, and long stout legs radiating laterally.
Size Estimate
Estimated leg span of 3 to 4 inches (75-100 mm), typical for a subadult or adult specimen.
Coloration & Markings
Muted tan to greyish-brown coloration, with subtle darker markings on the carapace and abdomen, enabling effective camouflage against tree bark or indoor surfaces.
Web Type
No web; Huntsman spiders are active cursorial hunters that stalk and overpower prey rather than using capture webs.
Eye Arrangement
Eight eyes arranged in two horizontal rows of four, providing wide-angle forward vision for hunting.
Leg Characteristics
Long, thick legs oriented laterally (crab-like posture), equipped with dense scopulae (adhesive foot pads) that allow them to climb smooth vertical walls effortlessly.
Venom & Safety Information
Venom Information
Mildly toxic to humans; intended to immobilize small insect prey.
Medical Significance
Not medically significant. Bites are extremely rare and typically result in minor localized pain and swelling similar to a bee sting.
Safety Recommendations
If removal is desired, gently trap the spider using a large plastic container and cardboard slide, then release it outdoors. Chemical pest control is generally unnecessary.
Habitat & Behavior
Habitat & Range
Pantropical and subtropical distribution worldwide; commonly found in structures, sheds, homes, and under tree bark or rock crevices.
Behavior & Temperament
Highly agile and rapid runners, nocturnal habits, timid disposition towards humans, preferring to flee quickly when disturbed.
Diet & Prey
Generalist predator consuming insects like cockroaches, moths, silverfish, and cricket pests.
Seasonal Activity
Active year-round in warm indoor environments or tropical climates, with peak outdoor activity during warmer, humid months.
Description
A classic indoor visitor in warm climates, the Huntsman spider is a swift, nocturnal predator that serves as natural pest control by hunting unwanted household insects.
Key Features
Flattened brownish body, sideways leg orientation, exceptional speed, and lack of a capture web on vertical walls.
Similar Species
Often confused with Nursery Web Spiders (Pisauridae) or Wolf Spiders (Lycosidae), but distinguished by its flattened body shape and lateral crab-like leg arrangement.
Life Cycle
Females carry a flat, disc-like silk egg sac beneath their bodies until spiderlings hatch. Lifespan is generally 1 to 2 years.
Ecological Importance
Serves as an essential apex invertebrate predator within domestic and wild habitats, maintaining low pest populations.
Conservation Status
Not evaluated (Least Concern); highly adaptable and widespread worldwide.
Interesting Facts
Despite their intimidating size and speed, Huntsman spiders are harmless to humans and are frequently welcomed in homes across tropical regions to control cockroach populations.
