Pantropical Giant Huntsman Spider, Cane Spider, Banana Spider
Heteropoda venatoria
Sparassidae (Huntsman Spiders), Order Araneae
Physical Description
Large, flattened body adapted for squeezing into tight crevices. The cephalothorax is broad and circular with a distinct dark Y-shaped or V-shaped mark. The abdomen is oval-shaped and hairy. Females are larger-bodied than males, while males have longer legs and bulbous pedipalps.
Size Estimate
Body length 2-3 cm (0.8-1.2 in); leg span can reach up to 10-15 cm (4-6 in). The specimen in the photo appears to be an adult.
Coloration & Markings
Generally light brown to grayish-brown with darker mottling. A characteristic cream-colored band (clypeal stripe) is visible on the 'face' below the eyes. Males often have a large dark patch on the cephalothorax and more prominent markings than females.
Web Type
None. This is a cursorial hunting spider. It does not spin webs for prey capture, though females spin silk to carry their egg sacs.
Eye Arrangement
Eight eyes arranged in two rows of four. The rows are horizontal; the bottom row is nearly straight and the top row is slightly curved.
Leg Characteristics
Long, robust legs that are held in a 'crab-like' lateral orientation. The legs are covered in fine hairs and prominent spines. They are extremely fast and capable of moving sideways or backward with ease.
Venom & Safety Information
Venom Information
Possesses venom used to immobilize insect prey. The venom is not considered medically significant to healthy humans; it is local-acting and much less potent than that of a widow or recluse spider.
Medical Significance
Low danger level. Bites are rare and usually occur only if the spider is squeezed. Symptoms typically include localized pain, redness, and minor swelling similar to a bee sting. No specific medical treatment is usually required unless an allergic reaction occurs.
Safety Recommendations
Use the 'cup and paper' method to relocate it outside if found indoors. Do not attempt to catch it with bare hands as it is very fast and may bite defensively. If bitten, clean the area with soap and water and use a cold compress for pain.
Habitat & Behavior
Habitat & Range
Found in tropical and subtropical regions worldwide, including the Southern US, Caribbean, Asia, and Hawaii. They prefer warm climates and are frequently found in and around human dwellings, sheds, and garages.
Behavior & Temperament
An active nocturnal hunter. They are generally shy and will flee rapidly if disturbed. While they can be defensive if cornered or handled, they are not naturally aggressive toward humans.
Diet & Prey
Primarily feeds on large insects such as cockroaches and crickets. They are celebrated in many tropical regions as natural pest controllers because of their appetite for household pests.
Seasonal Activity
Year-round in tropical climates. In subtropical regions, they are most visible during the summer months and may move indoors during cooler weather to find warmth.
Description
The Pantropical Huntsman is an impressive, large-scale spider often encountered by homeowners in warm climates. Its flattened profile and lateral leg span allow it to hide behind picture frames or under bark. Despite its size and speed, it is a beneficial roommate that hunts the insects most people find far more loathsome.
Key Features
Large size, flattened brown body, crab-like leg posture, and the distinctive light-colored mustache-like band on the front of its head.
Similar Species
Often confused with Wolf Spiders (Lycosidae), but identified by its lateral leg orientation. Also similar to the Brown Recluse, but significantly larger and lacking the distinct violin marking and specific eye pattern of Loxosceles.
Life Cycle
Females produce a large, flat, papery egg sac which they carry underneath their bodies using their pedipalps and chelicerae. They remain relatively immobile while carrying the sac until the spiderlings emerge. Lifespan is typically 1-2 years.
Ecological Importance
Highly beneficial for natural pest control. They are one of the few predators that actively hunt large cockroaches inside homes, reducing the need for chemical pesticides.
Conservation Status
Not evaluated by IUCN, but widespread and common. It is an invasive species in many parts of the world due to its tendency to hitchhike in shipping containers (especially banana shipments).
Interesting Facts
In Hawaii, they are known as 'Cane Spiders.' They are famous for their incredible speed, able to cover an entire wall in a second. They are also known to make a rhythmic 'ticking' sound during courtship by vibrating their abdomens against a surface.
Photography Tips
A side-on view of the face can capture the clypeal stripe, while a top-down view is best for showing the leg span and cephalothorax markings. Use a fast shutter speed to account for their sudden bursts of movement.
