Mansueti (1948:213) describing the habits of _laticeps_ in Maryland, Louisiana and elsewhere in the southern states, emphasizes its arboreal habits, referring to it as "'scorpion' of the treetops." He describes it as dashing up and down tree trunks, along fences, and in abandoned buildings. However, he states that it also spends much time on the ground, and may take refuge in holes and cracks near ground level, and gravid females are less arboreal, making their nests in decayed logs of chestnut or oak. He mentions individuals having been found living far above ground in tall trees, in nests of birds of prey. One old male that was frequently seen by him always retreated far up a dead chestnut tree that towered above the surrounding forest of scrub pine. Mansueti also mentions arboreal combats between males and implies that they are territorial. Taylor (1936:59) described _laticeps_ as typically an arboreal form, almost invariably found in trees, and he indicated that it has claws more curved than in other species--an obvious arboreal adaptation. Parker (1948:25), however, stated that "_E. laticeps_ is reputed to be rather arboreal, but field work in western Tennessee has not borne out this belief. A few of the specimens have been found in tall, dead trees, as has _E. fasciatus_." This statement evidently was based on a small number of observations. Cook (1943:15) mentions a female _laticeps_ found in a nest with a clutch of 27 eggs (hence certainly a communal nest of two or more females) in a burrow under a log, on July 8, 1941, in Lee County, Mississippi. This account is under the name _Eumeces fasciatus_ but the large size of the female precludes the possibility of it being either _fasciatus_ or _inexpectatus_. The remainder of Cook's account is evidently based on a composite of observations on all three species.
