Hentz Orb-Weaver, Spotted Orb-Weaver, Barn Spider
Neoscona crucifera
Family Araneidae (Orb-Weavers), Order Araneae. Key family characteristics include building vertical wheel-like webs, excellent vision focused on movement, and robust bodies suited for web construction.
Physical Description
The specimen shown is somewhat damaged or curled, but typically this species has a robust, oval to slightly triangular abdomen and a distinctively hairy carapace. Females are significantly larger and bulkier than males, with a high rounded abdomen capable of storing eggs.
Size Estimate
Body length typically ranges from 9 to 18 millimeters for adult females, with a leg span reaching up to 30 to 40 millimeters. The specimen in the image appears small or partially contracted, roughly 10 millimeters in total span.
Coloration & Markings
Varies widely from yellowish-brown to reddish-brown or dark grey. The abdomen often features a central pattern resembling a cross, chevron markings, or pale spots outlined in darker tones.
Web Type
Vertical orb web, typically constructed at night in gardens, porches, or structures. The web is large, circular, and features sticky spiral threads designed to catch flying nocturnal insects.
Eye Arrangement
Eight small eyes arranged in two rows on the anterior portion of the cephalothorax, typical of the orb-weaver family, with lateral eyes often grouped in pairs.
Leg Characteristics
Strong, moderately long legs featuring distinct dark and light banding, equipped with spines and specialized claws used for manipulating silk and navigating the web.
Venom & Safety Information
Venom Information
Contains mild neurotoxic venom tailored for subduing small insect prey. It is not considered dangerous or toxic to humans.
Medical Significance
Harmless to humans. A bite is extremely rare, typically only occurring if trapped against the skin, and usually results in nothing more than minor local irritation similar to a mosquito bite.
Safety Recommendations
No special safety measures are necessary. If found indoors, it can be gently guided into a container and relocated outside to a garden or wooded area.
Habitat & Behavior
Habitat & Range
Found widely across North America, particularly in eastern and central regions. Prefers gardens, woodlands, shrubs, and around human structures like porches and exterior walls where outdoor lighting attracts prey.
Behavior & Temperament
Generally nocturnal, spending daylight hours hiding in a nearby retreat or leaf curl, and moving to the center of the web at dusk. Highly docile and non-aggressive toward humans.
Diet & Prey
Primarily feeds on flying insects caught in its orb web, including moths, beetles, mosquitoes, and flies.
Seasonal Activity
Most active and noticeable during late summer and autumn when adults reach full size, build prominent webs, and engage in mating.
Description
The Hentz Orb-Weaver is a common and beneficial nocturnal hunter often encountered around homes and gardens in late summer and autumn. Known for building large, intricate wheel-shaped webs to capture flying pests, this robust spider plays a valuable role in natural insect control.
Key Features
Hairy carapace, variable reddish-brown to yellowish body with subtle dorsal markings, and the habit of constructing large vertical orb webs combined with a nocturnal lifestyle.
Similar Species
Other members of the genus Neoscona and various Araneus species (such as the Barn Spider, Araneus cavaticus). Distinguished by specific abdominal markings and genitalia upon close microscopic examination.
Life Cycle
Females construct silken egg sacs in protected crevices or foliage in the autumn, depositing hundreds of eggs before perishing. Spiderlings hatch in spring, disperse via ballooning, and mature by late summer.
Ecological Importance
Acts as an effective natural pest controller by consuming large quantities of flying insects, helping to regulate populations of agricultural and residential pests.
Conservation Status
Secure and widespread throughout its native range, with stable populations facing no significant threats.
Interesting Facts
These spiders often consume and rebuild their entire orb web every single day to maintain the stickiness and integrity of the silk structure.
Photography Tips
Best photographed at night using a macro lens and a diffuse flash to capture the spider sitting alert in the center of its web without disturbing it.
