Hentz Orb-Weaver, Spotted Orb-Weaver, Barn Spider
Neoscona crucifera
Araneidae (Orb-Weavers), Order Araneae. Key family characteristics include building vertical, wheel-like orb webs and having eight similar-sized eyes arranged in two rows.
Physical Description
The body consists of a distinct, hairy cephalothorax and a large, bulbous abdomen that is oval-shaped and slightly pointed at the rear. Females are noticeably larger and bulkier than males, featuring a tough yet slightly flexible exoskeleton covered in fine setae.
Size Estimate
Body length ranges from 9 to 18 millimeters for adult females, with a leg span reaching up to 30 to 40 millimeters. This specimen appears to be a mature adult female.
Coloration & Markings
Base coloration ranges from yellowish-brown to reddish-orange or dark brown. The abdomen typically features a distinct patterned dorsal marking, often including a cross-like or leaf-like pattern edged in darker tones, flanked by lighter spots.
Web Type
Builds a classic, large vertical orb web consisting of sticky spiral threads and non-sticky radial supports. It is typically constructed in the evening in open spaces, doorways, or between vegetation to intercept flying insects.
Eye Arrangement
Eight small eyes arranged in two distinct rows on the anterior portion of the cephalothorax, typical of orb-weavers, with the lateral eyes often grouped in pairs.
Leg Characteristics
Long, robust legs featuring distinct dark and light banding patterns, covered in numerous spines and hairs used for sensing vibrations in the web.
Venom & Safety Information
Venom Information
Contains mild neurotoxic and proteolytic venom tailored strictly for subduing insect prey. It poses no chemical threat to mammals or humans.
Medical Significance
Harmless to humans. A bite is extremely rare, usually only occurring if the spider is trapped, and typically results in minor, localized pain and redness similar to a mild mosquito bite.
Safety Recommendations
Leave the spider undisturbed to enjoy natural pest control. If relocation is necessary, gently guide the spider into a container using a piece of cardstock and release it into nearby garden foliage.
Habitat & Behavior
Habitat & Range
Found throughout North America, particularly in the eastern and central regions. Prefers gardens, woodland edges, porches, and the exteriors of buildings where artificial lights attract prey.
Behavior & Temperament
Nocturnal web-builders that often retreat to a hidden shelter or a corner of the web during the daytime, emerging at dusk to sit at the center of the orb web. They are docile, non-aggressive, and only bite if pressed directly against human skin.
Diet & Prey
Strictly carnivorous, feeding on flying insects such as moths, beetles, mosquitoes, flies, and occasional small wasps caught in the sticky spiral of the orb web.
Seasonal Activity
Most active during late summer and autumn when adults reach full size, build prominent webs, and mate before dying off with the first hard frost.
Description
The Hentz Orb-Weaver is a familiar and beneficial nocturnal neighbor, constructing intricate wheel-shaped webs near outdoor lights. With its warm reddish-brown tones and distinctive patterned abdomen, it is a master architect of the night, silently working to control flying insect populations around human dwellings.
Key Features
Large bulbous abdomen with a distinct cross or leaf-like dorsal pattern, hairy legs with dark banding, and construction of a large, temporary vertical orb web.
Similar Species
Other orb-weavers such as Araneus diadematus (European Garden Spider), which features a prominent white cross on the abdomen, and Neoscona domiciliorum (Redlegged Orb-Weaver).
Life Cycle
Females construct silken egg sacs containing hundreds of eggs in protected crevices during autumn. Spiderlings emerge in spring, dispersing via ballooning, and mature by late summer or fall.
Ecological Importance
Serves as an effective natural pesticide by consuming large quantities of flying agricultural and household pests, while acting as a vital food source for birds and small mammals.
Conservation Status
Secure and widespread throughout its native range, with stable populations facing no significant conservation threats.
Interesting Facts
Many orb-weavers consume their own webs daily to recycle the silk proteins and rebuild a fresh, sticky trap before the next nightfall.
Photography Tips
Photograph at dusk or night using a macro lens and a diffused flash to highlight the intricate patterns on the abdomen and the texture of the orb web without washing out details.
