Brown Huntsman Spider, Giant Crab Spider, Banana Spider (not to be confused with Argiope or Nephila), Cane Spider
Heteropoda venatoria
Sparassidae (Huntsman Spiders), Order Araneae
Physical Description
Large, dorsoventrally flattened body designed for squeezing into narrow crevices. The cephalothorax is broad with a prominent 'mustache' or pale band across the clypeus. The abdomen is oval-shaped and covered in fine, velvety hairs. Males are generally smaller with longer legs and more contrasting patterns.
Size Estimate
Body length of 20-30mm; leg span can reach 75-125mm (3 to 5 inches). This appears to be a mature specimen based on the well-defined markings.
Coloration & Markings
Tan to brown base color. Females have a dark brown stripe behind the eyes. Males have a dark, heart-shaped mark on the cephalothorax and more prominent banding on the legs. Both sexes possess a distinctive white or tan line across the front of the 'face'.
Web Type
Non-weaving hunter. Does not build a web for prey capture; it uses silk only for draglines and constructing egg sacs.
Eye Arrangement
Eight eyes in two rows of four. The eyes are relatively similar in size, though the anterior median eyes are often slightly smaller than the anterior lateral eyes, arranged for wide-angle panoramic vision.
Leg Characteristics
Long, powerful legs held in a lateral (crab-like) orientation. The legs are covered in short spines and fine hairs, often showing dark spots or maculations at the joints. The feet (tarsi) have claw tufts for climbing smooth surfaces.
Venom & Safety Information
Venom Information
Possesses neurotoxic venom designed to immobilize insects. The venom is not considered medically significant to healthy humans; it is comparable to a bee sting in localized intensity.
Medical Significance
Low danger level. Bites are rare and usually occur if the spider is squeezed. Symptoms include localized pain, slight swelling, and redness. No specific medical treatment is usually required beyond cleaning the site and applying a cold compress.
Safety Recommendations
If found indoors, they should ideally be left alone or relocated using a large container and a piece of cardboard. Avoid handling with bare hands. Use a vacuum for removal only if necessary, though relocation is preferred for their pest-control benefits.
Habitat & Behavior
Habitat & Range
Circumtropical distribution. Found in tropical and subtropical regions worldwide, including Southeast Asia, the Caribbean, and the Southern United States. Often found in houses, barns, and warehouses, or under loose tree bark.
Behavior & Temperament
Extremely fast and agile nocturnal hunter. It is generally shy and will flee rapidly when disturbed. While they can be defensive if cornered or handled, they are not typically aggressive toward humans. They do not use a sit-and-wait strategy but actively stalk prey.
Diet & Prey
Primarily insectivorous, feeding on cockroaches, silverfish, crickets, and moths. They are highly valued in many households for their ability to control cockroach populations without pesticides.
Seasonal Activity
Active year-round in tropical climates. In subtropical ranges, they are most visible during the warmer summer months and often move indoors when temperatures drop.
Description
The Brown Huntsman is a master of speed and stealth. Its flattened body allows it to hide behind picture frames and under bark during the day, emerging at night to sprint across walls and ceilings. Its 'crab-like' gait and massive leg span make it an intimidating sight, but it is one of the most beneficial 'roommates' a tropical homeowner can have due to its appetite for pests.
Key Features
Large leg span (up to 5 inches), flattened body, crab-like leg posture, and the distinctive white 'mustache' line on the front of the cephalothorax.
Similar Species
Holconia and Neosparassus species (mostly Australian), and potentially large Wolf Spiders (Lycosidae), which can be distinguished by their vertically-oriented legs and different eye patterns.
Life Cycle
Females carry their flat, disc-like silk egg sacs underneath their bodies using their pedipalps. They provide maternal care until the spiderlings hatch and disperse. Lifespan is typically around 1-2 years.
Ecological Importance
Crucial apex invertebrate predator in domestic and forest environments. They provide exceptional natural pest control against invasive cockroaches and other household insects.
Conservation Status
Not evaluated (NE). They are widespread and highly adaptable to human-altered environments, with stable populations.
Interesting Facts
Despite their size, they can walk on vertical glass panes and even upside down on ceilings thanks to specialized 'scopulae' hairs on their feet. They are often accidentally transported globally in shipments of bananas.
Photography Tips
Use a wide-angle macro lens to capture the full leg span. Focus specifically on the 'face' to show the mustache line and eye arrangement. Side profile shots help illustrate the incredibly flat body shape.
