Hentz Orbweaver, Spotted Orbweaver, Barn Spider
Neoscona crucifera
Araneidae (Orb-weavers), Order Araneae
Physical Description
A robust, classic orb-weaving spider featuring a large, bulbous, egg-shaped abdomen covered in fine setae (hairs), giving it a slightly velvety texture. The cephalothorax is relatively small and lighter in color, typically yellowish-tan or grey-brown with subtle darker shading.
Size Estimate
Adult females typically measure 10-20 mm in body length with a leg span up to 50 mm (2 inches). Males are smaller, ranging from 5-10 mm. This specimen appears to be an adult female based on the broad, full abdomen.
Coloration & Markings
Variable coloration ranging from rusty orange-brown to pale tan or yellowish grey. The dorsal abdomen features a distinct light-colored cruciform (cross-like) pattern framed by darker zig-zag or scalloped foliate lines. The underside (ventral) usually features two bright white spots on a dark patch.
Web Type
Large, vertical wheel-shaped orb web up to 1-2 feet (30-60 cm) in diameter. Often built near outdoor lights, porches, trees, and tall vegetation to capture flying insects. Web is frequently rebuilt nightly or consumed in the morning.
Eye Arrangement
Eight eyes arranged in two curved rows of four across the front of the cephalothorax. The median eyes are grouped closely together on a slight prominence, typical of the Araneidae family.
Leg Characteristics
Spiny, thick legs with distinct alternating dark reddish-brown and pale yellow-tan bands. Prominent macrosetae (spines) are clearly visible along the segments, aid in manipulating silk and prey.
Venom & Safety Information
Venom Information
Mild, weak venom designed to immobilize small insects. It poses no medical threat to humans or domestic pets.
Medical Significance
Not medically significant. Bites are extremely rare, usually occurring only if pinched or squeezed. Symptoms resemble a mild bee sting or minor local irritation, self-resolving within a few hours.
Safety Recommendations
Harmless and beneficial spider. Leave undisturbed outdoors. If in a high-traffic doorway, gently relocate using a cup and card to nearby bushes or garden foliage.
Habitat & Behavior
Habitat & Range
Widespread across North America, particularly abundant in central and eastern United States and parts of Mexico. Commonly found in gardens, backyards, agricultural fields, woodland edges, and around human structures like porches and fences.
Behavior & Temperament
Strictly nocturnal or crepuscular builder; usually hangs head-down at the center (hub) of its web at night. Docile, non-aggressive, and will drop to the ground or retreat into nearby foliage if threatened rather than bite.
Diet & Prey
Generalist predator feeding mainly on flying insects including moths, mosquitoes, beetles, flies, and stinkbugs caught in its sticky web. Fast-acting wrap-and-bite strategy.
Seasonal Activity
Most active and noticeable from late summer through autumn (August to November), which coincides with their mature phase and mating season.
Description
Neoscona crucifera, commonly known as the Hentz Orbweaver, is one of the most recognizable and beneficial late-summer and autumn spiders in eastern North America. Renowned for constructing magnificent geometric orb webs, this spider helps naturally control flying insect populations around homes and yards.
Key Features
Cruciform (cross-like) pattern on the dorsal abdomen, reddish-orange to tan background color, hairy/velvety texture, prominent leg banding, and two white spots on the black ventral side.
Similar Species
Neoscona domiciliorum (Redfemur Orbweaver, has red femora), Araneus cavaticus (Barn Spider), and Araneus diadematus (Cross Orbweaver, which has distinct white cross dots rather than a pale soft pattern).
Life Cycle
Annual life cycle. Females lay several hundred eggs in a tough, yellowish silk sac tucked into foliage or structure crevices during autumn before dying with the first frosts. Spiderlings emerge in spring, disperse via ballooning, and mature by late summer.
Ecological Importance
Serves as an essential natural pest regulator, suppressing populations of nocturnal pests like moths, beetles, and mosquitoes. Also acts as a food source for birds, wasps, and small reptiles.
Conservation Status
Common and widespread (Not Evaluated on IUCN Red List), with stable populations thriving in suburban and modified habitats.
Interesting Facts
Hentz Orbweavers routinely consume their own web every morning, ingesting the protein-rich silk to recycle it, and then spin a completely new web the following evening in under an hour.
Photography Tips
Photograph at night with a gentle flash or soft torch light to highlight the geometric web structure and contrast the rich abdominal patterns against a dark background. Capture macro photos of the carapace and dorsal pattern for definitive identification.
