Barn Orb-Weaver, Hentz Orb-Weaver
Neoscona crucifera
Family Araneidae (Orb-Weavers), Order Araneae
Physical Description
The body is robust with a rounded, hairy abdomen that is significantly wider than the cephalothorax, typical of many orb-weavers. Females are noticeably larger than males, displaying a bulbous abdomen well-suited for egg production.
Size Estimate
Body length ranges from 9 to 19 mm for females and 8 to 13 mm for males, with a total leg span reaching up to 30 to 40 mm. This specimen appears to be an adult or sub-adult.
Coloration & Markings
Coloration ranges from yellowish-brown to reddish-brown or greyish. The abdomen often features a leaf-like pattern or a distinct cross shape, accompanied by dark spots and alternating light and dark bands.
Web Type
Builds a classic vertical orb web made of sticky silk, typically constructed at night in or near structures, gardens, and porches, and often taken down or rebuilt daily.
Eye Arrangement
Features eight eyes arranged in two rows of four, with the lateral eyes often paired closely together, typical of the Araneidae family.
Leg Characteristics
Legs are moderately long, hairy, and heavily banded with dark brown and light tan rings, equipped with claws adapted for navigating silk webs.
Venom & Safety Information
Venom Information
Possesses mild neurotoxic venom used primarily to subdue insect prey. It is not potent or dangerous to humans.
Medical Significance
Medically insignificant. A bite is rare, usually only occurring if the spider is trapped directly against the skin, and typically results in only mild, localized pain and minor swelling similar to a mosquito bite.
Safety Recommendations
No special precautions needed. If found inside a house, it can be gently guided into a container and relocated outdoors to a garden or porch.
Habitat & Behavior
Habitat & Range
Commonly found throughout North America, particularly in eastern and central regions. Prefers outdoor environments near human habitations, barns, porches, gardens, and wooded edges.
Behavior & Temperament
Generally nocturnal, spending daylight hours hiding in a nearby retreat or clinging to the edge of the web. Very docile and non-aggressive toward humans, typically dropping or retreating if disturbed.
Diet & Prey
Feeds primarily on flying insects such as moths, beetles, flies, and mosquitoes intercepted by its vertical orb web.
Seasonal Activity
Most active and visible during the warm summer and autumn months, with peak mating and web-building activity occurring in late autumn.
Description
The Barn Orb-Weaver is a familiar and beneficial nocturnal architect often spotted near outdoor lights where prey gathers. With its hairy, patterned body and expertly spun vertical wheel web, it serves as a wonderful garden resident that helps manage pest insect populations.
Key Features
Rounded, hairy abdomen with brownish coloration, distinct cross or leaf-like dorsal markings, and association with large vertical orb webs near artificial lights or structures.
Similar Species
Other Araneus and Neoscona species, such as Neoscona domiciliorum (The Red Femured Orb-Weaver). Distinguished by subtle differences in ventral markings, epigynum structure in females, and specific dorsal patterns.
Life Cycle
Mates in late summer and autumn. Females lay eggs inside a protective silk sac attached to sheltered surfaces, where the eggs overwinter before spiderlings hatch in spring.
Ecological Importance
Acts as an effective natural pest control agent by consuming large quantities of flying insects, maintaining balance within local garden and woodland ecosystems.
Conservation Status
Secure and widespread; not threatened or endangered globally.
Interesting Facts
Barn orb-weavers are known to consume and recycle their own webs daily to reclaim proteins and amino acids used in producing the silk.
Photography Tips
Best photographed at night using a macro lens and ring flash or diffused external flash when the spider is active in the center of its web.
