Hentz Orb-Weaver, Spotted Orb-Weaver
Neoscona crucifera
Family Araneidae (Orb-Weavers), Order Araneae
Physical Description
The spider has a rounded, bulbous abdomen typical of orb-weavers, a smaller hairy cephalothorax, and robust proportions adapted for hanging upside down in a web.
Size Estimate
Body length ranges from 10 to 18 mm for females with a leg span of approximately 30 to 40 mm; this appears to be a mature or subadult female.
Coloration & Markings
Warm brownish to yellowish-orange base coloration with distinctive dark brown to black banding on the legs and mottled, leaf-like or cross-like patterns on the dorsal abdomen.
Web Type
Vertical orb web constructed with sticky spiral threads, typically built in foliage, near outdoor lighting, or between structures, measuring up to several feet across.
Eye Arrangement
Eight small eyes arranged in two slightly recurved rows, with the median eyes situated on a slight raised tubercle, typical of the orb-weaver family.
Leg Characteristics
Long, strong legs featuring prominent dark and light alternating bands and visible spination, held defensively or spread out widely in a typical orb-weaver resting posture.
Venom & Safety Information
Venom Information
Neurotoxic venom tailored specifically for immobilizing invertebrate prey; virtually harmless to humans and large mammals.
Medical Significance
Not medically significant. A bite may cause minor, temporary local pain or swelling akin to a mild bee sting, but these spiders rarely bite unless directly trapped or squeezed.
Safety Recommendations
No special safety measures are needed beyond avoiding bare-hand contact when cleaning up outdoor webs; can be gently relocated using a cup and piece of paper.
Habitat & Behavior
Habitat & Range
Common throughout eastern and central North America, preferring gardens, woodlands, forest edges, and often found around human structures like porches and exterior walls.
Behavior & Temperament
Docile and non-aggressive; constructs a new web or repairs it nightly, often retreating to a nearby leaf or hiding spot during daylight hours.
Diet & Prey
Generalist insectivore feeding on flying pests such as moths, beetles, mosquitoes, and flies captured in its vertical orb web.
Seasonal Activity
Most commonly seen and mature during late summer and autumn when females reach full size and construct egg sacs before dying off with the first hard frosts.
Description
Neoscona crucifera, commonly known as the Hentz Orb-Weaver, is a familiar nocturnal architect of gardens and outdoor spaces. With its beautifully patterned, bulbous abdomen and banded legs, it spends its nights hanging in the center of a finely spun orb web waiting for passing prey, playing an essential role in controlling insect populations.
Key Features
Bulbous brownish abdomen with subtle patterning, prominently banded legs, and the habit of constructing large vertical orb webs combined with a nocturnal lifestyle.
Similar Species
Other orb-weavers such as Neoscona domiciliorum (The Redfemured Orb-Weaver) and Araneus diadematus (European Garden Spider), distinguished by specific abdominal markings and color hues.
Life Cycle
Females construct silken egg sacs in protected crevices during autumn containing hundreds of eggs; spiderlings emerge in spring and disperse via ballooning.
Ecological Importance
Serves as an effective natural pesticide by consuming large quantities of flying insects and forms a vital food source for birds and small mammals.
Conservation Status
Not evaluated by the IUCN, but populations are stable, widespread, and highly adaptable to human-modified environments.
Interesting Facts
Many orb-weavers consume their old webs daily to recycle the proteins before spinning a fresh one just before dusk.
Photography Tips
Use macro lenses with a ring flash or diffused external lighting at night when the spider is active in its web to highlight its intricate dorsal patterns and leg banding.
