Hentz Orb-Weaver, Spotted Orb-Weaver
Neoscona crucifera
Araneidae (Orb-Weavers), Order Araneae
Physical Description
Robust, stout body with a rounded, bulbous abdomen and a smaller cephalothorax. The abdomen is typically wide and slightly flattened or domed dorsally, showcasing subtle folium patterns or spots. Females are significantly larger and bulkier than males.
Size Estimate
Body length typically ranges from 9 to 19 mm for females and 7 to 14 mm for males, with a substantial leg span reaching up to 40 mm. This specimen appears to be an adult female.
Coloration & Markings
Variable coloration ranging from light brown, yellowish-orange, to reddish-brown or grayish. The abdomen often features a faint cross-like or leaf-like pattern (folium) outlined in darker tones, sometimes accompanied by whitish or yellowish spots.
Web Type
Classic vertical orb web, a finely spun circular wheel of sticky silk used to intercept flying insect prey. Usually constructed in the evening near outdoor lights, porches, or garden foliage.
Eye Arrangement
Eight eyes arranged in two distinct rows on the anterior cephalothorax, consisting of four central median eyes and two lateral pairs, typical of the orb-weaver family Araneidae.
Leg Characteristics
Moderately long, robust legs equipped with prominent spines and distinct dark banding or rings. They are typically held outward or tucked closely to the body when resting in the center of the web.
Venom & Safety Information
Venom Information
Contains mild neurotoxic or proteolytic venom designed specifically to immobilize small invertebrate prey. It poses no chemical threat to humans.
Medical Significance
Harmless and not medically significant. A bite can occasionally occur if the spider is accidentally trapped against the skin, resulting in minor, temporary localized pain and redness comparable to a mild insect sting.
Safety Recommendations
Leave undisturbed outdoors where it poses no risk. If found inside a house, gently guide the spider into a container using a piece of paper and relocate it to an outdoor garden.
Habitat & Behavior
Habitat & Range
Found throughout North America, particularly east of the Rocky Mountains. Prefers gardens, woodlands, forest edges, and human structures such as exterior walls, porches, and around outdoor lighting fixtures.
Behavior & Temperament
Docile and non-aggressive. Nocturnal builder, often hanging upside down in the center of its web at night and retreating to a nearby crevice or leaf shelter during daylight hours.
Diet & Prey
Feeds primarily on flying insects such as moths, beetles, mosquitoes, and flies captured in its vertical orb web.
Seasonal Activity
Most active during late summer and autumn when adults reach full size, build prominent webs, and engage in mating before dying off with the first hard frosts.
Description
The Hentz Orb-Weaver is a quintessential garden spider known for constructing intricate, wheel-shaped webs in the evening. With its rounded, patterned abdomen and steady nocturnal habits, it acts as a silent and efficient guardian against flying pest insects around homes and gardens.
Key Features
Rounded, bulbous abdomen with a subtle folium or cross pattern, hairy or spiny banded legs, and the construction of a large, vertical wheel-shaped orb web.
Similar Species
Neoscona arabesca (Arabesque Orb-Weaver), which tends to have a more distinct light and dark pattern on the dorsal abdomen; and Araneus diadematus (European Garden Spider), which features prominent white cross markings.
Life Cycle
Mates in late summer or autumn. Females produce tough, silken egg sacs containing hundreds of eggs attached to sheltered surfaces. Spiderlings hatch in spring, often dispersing via ballooning on wind currents.
Ecological Importance
Serves as an essential natural predator of flying insect populations, helping to control pest species while acting as a food source for birds and small mammals.
Conservation Status
Not evaluated by the IUCN, but populations are widespread, stable, and highly abundant across its native range.
Interesting Facts
Many orb-weavers consume and recycle their entire web every single morning to recoup protein before building a fresh one the following evening.
Photography Tips
Photograph at night when the spider is active in the center of its web. Use a macro lens with a flash or external light source to highlight the intricate patterns on the abdomen and the fine structure of the silk.
