Brown Huntsman Spider, Giant Crab Spider, Banana Spider, House Huntsman
Heteropoda venatoria
Sparassidae (Huntsman Spiders), Order Araneae. Characterized by a flattened body and crab-like leg orientation.
Physical Description
A large spider with a distinctive flattened cephalothorax and abdomen, allowing it to squeeze into tight crevices. They have a fuzzy/hairy texture and legs that are oriented laterally (crab-like).
Size Estimate
Body length is typically 0.8–1.0 inches (22–28 mm), with a leg span reaching up to 3–5 inches (75–127 mm). This specimen appears to be an adult.
Coloration & Markings
Mostly brown or tan. Females have a more uniform brown color, while males are lighter with a distinct dark pattern on the cephalothorax and a light 'mustache' band on the clypeus (face).
Web Type
None. This is a cursorial hunting spider. It does not spin webs for prey capture, though it may produce silk for draglines or egg sacs.
Eye Arrangement
Eight eyes in two horizontal rows of four; those in the posterior row are usually larger or more prominent, providing excellent vision for nocturnal hunting.
Leg Characteristics
Exceptionally long and powerful legs with a laterigrade (forward-sideways) orientation. They are often sparsely hairy with small black spines visible upon close inspection.
Venom & Safety Information
Venom Information
Contains mild neurotoxins designed to immobilize insects. Not considered dangerously toxic to humans; comparable to a bee sting in localized pain.
Medical Significance
Low danger level. Bites are rare and usually only occur if the spider is pinched or squeezed. Symptoms include localized pain, redness, and swelling; no special treatment is typically required.
Safety Recommendations
If you wish to move it, use the 'cup and paper' method. Be prepared for it to run very quickly. There is no need for pest control as they do not infest or damage homes.
Habitat & Behavior
Habitat & Range
Common in tropical and subtropical regions worldwide (Florida, Texas, Hawaii, SE Asia, Australia). Often found indoors in bathrooms, garages, and sheds.
Behavior & Temperament
Extremely fast-moving and agile. They are non-aggressive toward humans and will usually sprint away when disturbed. Primarily nocturnal hunters.
Diet & Prey
Generalist predators feeding on cockroaches, silverfish, crickets, flies, and moths. They are highly valued as natural pest control in homes for their ability to hunt large roaches.
Seasonal Activity
Active year-round in tropical climates. In subtropical regions, they are most visible during the warmer months and may seek indoor shelter during cold snaps.
Description
The Brown Huntsman is a large, imposing, but ultimately beneficial indoor companion. Its speed is legendary, able to traverse walls and ceilings with startling efficiency while tracking down pests.
Key Features
Large size, flattened body, crab-like leg posture, and the absence of a capture web. Look for the white or cream-colored band across the 'face' beneath the eyes.
Similar Species
Often confused with Wolf Spiders (Lycosidae), but Wolf Spiders have different eye arrangements and more vertical leg postures. Also similar to other Sparassid species like the Olios genus.
Life Cycle
Females carry their large, flat, silken egg sacs beneath their bodies with their pedipalps and chelicerae. They exhibit maternal care until spiderlings hatch and disperse.
Ecological Importance
Critical apex predator within the micro-ecosystem of human dwellings and gardens, keeping population numbers of urban pests in check.
Conservation Status
Not evaluated by the IUCN, but generally considered abundant and stable due to their successful adaptation to human-modified environments.
Interesting Facts
Despite their scary appearance, they are welcomed in many tropical households as 'roommates' because they are more effective than chemicals at controlling cockroach populations.
Photography Tips
As seen in this photo, shooting from below reflects their typical ceiling/wall position. Use a flash to highlight the facial markings and eye arrangement for better identification.
