Castianeira crocata
Red-spotted Ant-mimic Sac Spider, Red Stripe Spider
Castianeira crocata is a small ant-mimic spider in the family Corinnidae, first described by Nicholas Marcellus Hentz in 1847. It is found in the United States. The species has a black body with distinctive red dorsal markings, a color pattern that can lead to misidentification as a black widow spider despite its very different body shape. Like other Castianeira species, it exhibits ant-mimicry behaviors and morphology.
