Hentz Orb-Weaver, Spotted Orbweaver
Neoscona crucifera
Family Araneidae (Orb-Weavers), Order Araneae
Physical Description
Robust, stout body with a rounded, bulbous abdomen and a smaller, hairy cephalothorax typical of orb-weavers. Females are significantly larger and rounder than males, possessing strong, hairy legs adapted for web construction.
Size Estimate
Body length ranges from 9 to 18 millimeters for adult females, with a leg span of approximately 25 to 40 millimeters. This specimen appears to be a well-fed adult female.
Coloration & Markings
Warm reddish-brown to yellowish-orange coloration with a distinctly patterned, hairy abdomen featuring subtle white or light spots and a central leaf-like or cross-shaped folium marking, though patterns can be quite variable.
Web Type
Constructs large, vertical circular orb webs made of sticky silk, typically built in the evening across open spaces, doorways, or between garden plants to intercept flying insects.
Eye Arrangement
Eight small eyes arranged in two rows on the front of the cephalothorax, typical of the orb-weaver family Araneidae, with lateral eyes often paired.
Leg Characteristics
Moderately long, robust legs featuring distinct dark and light banding patterns, equipped with numerous spines and specialized claws for navigating sticky orb webs without getting trapped.
Venom & Safety Information
Venom Information
Contains mild neurotoxic venom used primarily to subdue small invertebrate prey. It poses no chemical or medical threat to humans or large pets.
Medical Significance
Not medically significant. Bites are extremely rare, usually only occurring if the spider is squeezed or trapped against human skin, and result in minor, localized pain and swelling akin to a mild bee sting.
Safety Recommendations
No special safety measures are required. If found indoors, gently cup the spider under a glass and release it outdoors into a garden or wooded area.
Habitat & Behavior
Habitat & Range
Found widely across North America, particularly in the eastern and central regions, inhabiting gardens, woodlands, forests, and around human structures such as porches, exterior walls, and outdoor lighting.
Behavior & Temperament
Docile and non-aggressive toward humans. Nocturnal in web activity, often retreating to a nearby leaf or crevice during daylight hours, though they may sit at the hub of the web at night.
Diet & Prey
Generalist predator feeding on flying insects including moths, beetles, mosquitoes, flies, and occasional grasshoppers caught in its sticky orb web.
Seasonal Activity
Most active during late summer and autumn when adults reach full size and construct prominent webs, before dying off with the onset of winter frost, leaving behind overwintering egg sacs.
Description
The Hentz Orb-Weaver is a familiar and beneficial garden resident, recognized by its plump, patterned abdomen and remarkable nighttime orb webs. As a master architect of the insect world, it quietly patrols gardens, keeping pest populations in check while posing no danger to humans.
Key Features
Bulbous, hairy, patterned abdomen; reddish-brown and orange coloration; distinct leg banding; and association with large vertical orb webs.
Similar Species
Other orb-weavers such as Neoscona domiciliorum (Barn Spider) and Araneus cavaticus, which can be distinguished by subtle differences in abdominal markings and ventral coloration.
Life Cycle
Mating occurs in late summer or autumn, after which females deposit spherical silk egg sacs containing hundreds of eggs in protected crevices. Spiderlings emerge in spring to disperse via ballooning.
Ecological Importance
Acts as an effective natural pest control agent by consuming large numbers of flying insect pests, and serves as a vital food source for birds and small mammals.
Conservation Status
Secure and widespread throughout its native geographic range, with robust populations that benefit from human-modified environments like suburban gardens.
Interesting Facts
Many orb-weavers consume and recycle their entire web daily to recover proteins used in silk production before spinning a fresh one for the night.
Photography Tips
Use macro lenses with adequate natural side-lighting or a diffused flash to highlight the intricate patterns on the abdomen while maintaining a safe, non-disturbing distance.
