Abdomen shape with 10-12 rounded humps. Coloration typcially varios shades of brown, some showing a white band. Cephalothorax color varies like the abdomen, legs can be banded brown and white in either sex. In retreat often folds legs in front to a point. It is exceedingly difficult to separate some Acanthepeira specimens from the southeastern United States and it appears that three species interbreed. A. cherokee - Females (8.5-10.5 mm) may differ from other species in this genus by having smaller/less distinct abdominal humps. Males (6.5-11 mm) have 4th coxa without tubercle. Habitat is moist bottomland woods. A. marion - Females (10-15.5 mm) easily recognized by rounded humps. Males (7-10.5 mm) have 4th coxa with tubercle. A. stellata - Females (7-15 mm) Larger than venusta, more rounded, darker, deeply colored abdomen. Of the 4 species this is the only one which has AMEs smaller than secondary eyes. Female scape can be variable, esp. those from FL. Males (5-8 mm) have 4th coxa with tubercle and retrolateral macrosetae of fourth femur about equal in size. A. venusta - Females (6-10 mm) Can be distinguished by smaller size, narrow abdomen & lighter less contrasting pattern. This is the only species that might have ventral white marks. It might have a white transverse mark or two white spots behind the genital groove. Males (5-7.5 mm) have 4th coxa without tubercle. |

| prey |
Preys on grasshopper nymphs and other medium sized insects including a rare occurrence of a green tree frog. |
| predators |
Starbellied Orbweavers are often found in the larval mud cells of mud daubers. |
| behavior |
Likely similar to others in this genus, Nocturnal but not strictly, builds a 6-10" orb web in vegetation up to four feet in height. Female spends the night in hub of web facing down. Easily disturbed it can drop from web to disappear in vegetation or to feign death. During the day it rests in a retreat. Egg sacs are a loose brown silk mass attached to a leaf. |
