Hentz Orb-Weaver, Spotted Orbweaver
Neoscona crucifera
Family Araneidae (Orb-Weavers), Order Araneae
Physical Description
Robust, stout-bodied spider with a clearly segmented cephalothorax and a large, bulbous, oval to somewhat triangular abdomen that often features distinct humps or tubercles near the front. Females are significantly larger and bulkier than males.
Size Estimate
Body length typically ranges from 9 to 19 mm for adult females, with males being smaller around 7 to 14 mm. Leg span can reach up to 3 to 4 cm.
Coloration & Markings
Variable coloration ranging from straw-yellow, orange-brown, to reddish-brown or dark grey. The dorsal abdomen typically features a distinct pattern, often with a central cross-like or leaf-like folium marking bordered by dark lines and lighter spots.
Web Type
Vertical orb web constructed with sticky spiral threads, typically spanning 1 to 2 feet in diameter. Often built suspended between vegetation and structures like walls or porches.
Eye Arrangement
Eight eyes arranged in two rows of four (anterior and posterior rows), typical of the orb-weaver family Araneidae, with lateral eyes often grouped in pairs.
Leg Characteristics
Moderately long, strong legs adorned with distinct dark and light banding, prominent spines, and specialized claws for manipulating silk and navigating the web.
Venom & Safety Information
Venom Information
Neurotoxic/cytotoxic venom tailored to immobilize small invertebrate prey. Very low potency regarding humans.
Medical Significance
Not medically significant. A bite can cause mild, localized pain, redness, or swelling similar to a mosquito bite, but they rarely bite unless trapped against the skin.
Safety Recommendations
Leave undisturbed if found outdoors. If relocation indoors is necessary, gently guide the spider into a container using a piece of cardstock and release it outside.
Habitat & Behavior
Habitat & Range
Widespread across North America, particularly the eastern and central regions. Frequently found in gardens, forest edges, shrubs, and around outdoor human structures like porches and exterior walls.
Behavior & Temperament
Docile and non-aggressive. Often hides in a nearby retreat or sits in the center of the web during nighttime hours, retreating to foliage or cracks during the day.
Diet & Prey
Generalist insectivore feeding primarily on flying insects such as mosquitoes, flies, moths, beetles, and small wasps caught in its orb web.
Seasonal Activity
Most active and visible during late summer and autumn when adults reach maturity and females lay eggs.
Description
The Hentz Orb-Weaver is a quintessential garden spider frequently encountered weaving its intricate vertical wheel webs near lights or foliage. With its distinctive patterned abdomen and nocturnal habit of constructing fresh webs, it serves as a wonderful, beneficial neighbor for pest control.
Key Features
Bulbous hairy abdomen with a folium or cross-like pattern, vertical orb-web construction, and nocturnal web-building habits.
Similar Species
Neoscona arabesca (Arabesque Orbweaver), which is generally smaller with more elaborate markings, and Araneus diadematus (European Garden Spider), which features distinct white spots forming a cross.
Life Cycle
Females construct silk egg sacs in sheltered crevices or foliage in autumn containing hundreds of eggs. Spiderlings hatch in spring, often dispersing via ballooning.
Ecological Importance
Acts as a natural pest control agent by significantly reducing populations of flying nuisance insects like mosquitoes and flies.
Conservation Status
Not evaluated by the IUCN, but populations are secure, widespread, and abundant throughout their range.
Interesting Facts
Many orb-weavers consume their own webs daily to recycle the protein-rich silk before spinning a fresh one in the evening.
Photography Tips
Best photographed at night using a flash to highlight the web and dorsal patterns clearly, maintaining a safe macro distance without disturbing the spider.
