Appearance

As a member of the -mimicking Synageles, this exhibits morphological adaptations for myrmecomorphy (ant mimicry). The is more convex in the cephalic area and sharply declivous (downward sloping) behind the third row of . The spider holds its second pair of legs aloft to create the illusion of , enhancing its resemblance to ants. Specific coloration and pattern details for S. noxiosus are not well documented in available sources.

Habitat

Found in a variety of across its North American range, including areas where ants are abundant. Specific microhabitat preferences are not well documented, but like other -mimicking spiders, it likely occurs in habitats where its ant models are common.

Distribution

North America (United States, Canada, Mexico) and the Bahama Islands.

Behavior

Exhibits -mimicking , holding the second pair of legs aloft to simulate . This myrmecomorphy is thought to provide protection from that avoid ants, and may facilitate access to ant-associated resources.
