Neoscona crucifera is an orb-weaver spider in the family Araneidae. It is found in the United States from Maine to Florida in the east, to Minnesota in the Midwest, to Arizona in the southwest, southern California coastal communities and in Mexico. Its common names include Hentz orbweaver (after Nicholas Marcellus Hentz),[1] spotted orbweaver, and barn spider.[2] The name "barn spider" is also commonly used for a different spider, Araneus cavaticus.
Generally nocturnal, females may become diurnal in the fall.[3] Females are about 9.5–19 millimeters (0.37–0.75 in) long, while males are somewhat smaller. The upper surface of the abdomen is brown and hairy. The legs display alternating light and dark brown bands. The undersurface of the abdomen is black, with two white spots.
This species is relatively variable in color and sometimes pattern, but is most commonly seen sporting a rusty-red or golden orange color. The orb-shaped web is very large and is often constructed on buildings and other man-made structures, often several feet above ground, especially near outdoor lights. This species is most conspicuous in late summer and early fall.[4]
The orb part of the web may be nearly 2 feet (0.61 m) in diameter.[5] The eggsac consists of fluffy yellow threads in a rolled leaf over a lenticular or spherical egg mass 5–12 mm (0.20–0.47 in) in diameter, which may contain up to 1,000 eggs. Juveniles are frequently preyed upon by mud daubers.[6] This species will bite if provoked, but its venom is not dangerous to humans.[7]

Neoscona crucifera (лат.) — северо-американский вид аранеоморфных пауков рода Neoscona из семейства пауков-кругопрядов (Araneidae), называемый также пауком-кругопрядом Хентца (англ. Hentz's orbweaver). Иногда этот вид называют «овинный паук» (англ. barn spider), [1] хотя чаще под этим названием имеют в виду другой похожий вид Araneus cavaticus.
Neoscona crucifera обитает в США от Мэна до Флориды на востоке и от Миннесоты на Среднем Западе до Аризоны на юго-востоке и в Мексике. Был зарегистрирован также на Канарских островах и на побережье Африки.
N. crucifera ведёт ночной образ жизни, хотя осенью самки могут переходить и на дневной образ жизни. Днём прячется в свёрнутом листе, ночью располагается в центре паутины либо обновляет ловчую сеть. Размер самки 8—20 мм, самцы — меньше 4—15 мм. Верхняя брюшная сторона паука коричневая, покрыта волосками, две симметричные зигзагообразные линии образуют рисунок, напоминающий крест, что и обусловило видовое название «крестоносный». Нижняя сторона брюшка чёрная с двумя яркими белыми пятнами. Конечности с чередующимися светлыми и тёмными коричневыми полосами.
Паутина достигает 60 см в диаметре.
