Hentz Orb-Weaver, Spotted Orb-Weaver
Neoscona crucifera
Araneidae (Orb-Weavers), Order Araneae. Key family characteristics include building vertical, wheel-like orb webs and possessing eight similar eyes arranged in two rows.
Physical Description
The spider has a robust, rounded abdomen and a distinct cephalothorax covered in fine hairs. Females are noticeably larger and bulkier than males, with a swollen abdomen adapted for carrying eggs.
Size Estimate
Body length typically ranges from 10 to 18 millimeters for females, with a leg span of roughly 30 to 45 millimeters, placing this specimen in the adult range.
Coloration & Markings
Displays a mottled pattern of brown, tan, and reddish hues with subtle light and dark bands across the legs and distinct markings on the dorsal abdomen, often featuring a leaf-like or cross pattern.
Web Type
Builds a classic, large vertical orb web characterized by sticky spiral threads and a non-sticky hub, usually constructed at dusk in open spaces, doorways, or porches to catch flying insects.
Eye Arrangement
Features eight eyes arranged in two distinct rows on the anterior portion of the cephalothorax, consisting of lateral pairs and a central quadrangle, typical of the orb-weaver family.
Leg Characteristics
Legs are moderately long, thick, and strongly spined, featuring distinct dark banding patterns and held in a spread posture when resting on the web hub.
Venom & Safety Information
Venom Information
Utilizes a mild neurotoxic venom designed specifically to immobilize small invertebrate prey rapidly; it poses no chemical threat to humans.
Medical Significance
Medically insignificant. A bite is extremely rare, comparable in pain and effect to a mild bee sting or mosquito bite, causing localized redness and minor swelling that resolves quickly.
Safety Recommendations
No special safety measures are required. If an individual builds a web in an inconvenient location, it can be gently relocated using a cup and piece of paper.
Habitat & Behavior
Habitat & Range
Common throughout North America, frequently inhabiting gardens, woodlands, and structural frameworks like porches, eaves, and fences where adequate anchor points for large webs exist.
Behavior & Temperament
Nocturnal web-builders that typically retreat to a nearby hiding spot or hang quietly at the center of the web during the day. They are non-aggressive and only bite if trapped or squeezed.
Diet & Prey
Feeds primarily on flying insects such as moths, beetles, mosquitoes, and flies intercepted by the sticky spiral threads of the orb web.
Seasonal Activity
Most visible and active during late summer and autumn when individuals reach full adult size and construct prominent webs.
Description
The Hentz Orb-Weaver is a master architect of the night, spinning large, symmetrical wheel webs to capture winged insects. With its mottled brown tones and robust build, it blends seamlessly into wooden structures and garden foliage, serving as a welcome, natural pest controller around homes.
Key Features
Robust, hairy, bulbous abdomen with mottled brownish coloration, distinct leg banding, and construction of a large vertical orb web.
Similar Species
Other orb-weavers in the genus Neoscona or Araneus, which can be distinguished by specific subtle variations in the dorsal abdominal markings and genital morphology.
Life Cycle
Mating occurs in autumn, after which females construct silken egg sacs attached to sheltered surfaces. Spiderlings hatch in spring, undergo multiple molts, and reach maturity by late summer.
Ecological Importance
Acts as a primary biological control agent for flying insect populations, helping regulate densities of nocturnal pests like moths and mosquitoes.
Conservation Status
Not evaluated by the IUCN, but populations are secure, widespread, and highly adaptable to human-modified environments.
Interesting Facts
These spiders frequently consume and rebuild their entire orb web every single night to maintain the stickiness and integrity of the silk threads.
Photography Tips
Use a macro lens with a fast shutter speed or flash to freeze motion in low-light evening conditions. Shoot from the side or slightly above to capture web symmetry and dorsal markings clearly.
