Under a magnification of 40X, this scanning electron micrograph (SEM) revealed some of the ultrastructural architecture found in a brown recluse spider's, Loxesceles reclusa, web that had entrapped an unidentified ant. Though the prey had been enwrapped in a silk cocoon, there were still some of its body parts that were visible such as one of its two compound eyes, and one of its two segmented antennae (background). The antenna is composed of three main regions: scape, pedicle, and flagellum. The scape attaches the sensory organ to the head region, and the pedicle joins the distal, jointed flagellum to the scape.
