Neoscona crucifera (Spotted Orb Weaver)
Family: Araneidae Habitat: Woodlands, gardens, fields, and human structures across North America Activity: Primarily nocturnal; females may be active during daylight in late summer and fall
Identification: This image documents an adult Neoscona crucifera engaged in prey capture and wrapping behavior. The spider is suspended in partial web remnants, with its legs tightly gripping a shield-shaped insect—likely a stink bug (Pentatomidae). The spider’s abdomen is bulbous and patterned, with banded, hairy legs typical of the species.
Behavioral Notes: Spotted orb weavers construct large, circular orb webs, typically rebuilt nightly and consumed by morning. This specimen appears to be utilizing residual silk strands for prey capture, suggesting either opportunistic hunting or reduced web-building activity—common in gravid females or during seasonal transitions.
Ecological Role: Neoscona crucifera is a beneficial predator, contributing to insect population control. Its ability to subdue chemically defended prey like stink bugs highlights its ecological versatility and importance in integrated pest management.
