The blue monkeys live in female-[[Philopatry|philopatric]] social systems where females stay in their natal groups, while males disperse once they reach adulthood.<ref name=Forster/> As a result, blue monkey groups usually consist of one male with several females and infants, giving rise to matrilinear societies.<ref name=Forster/><ref name=Cords86/><ref name=Cords/> Occasionally, solitary males are observed, which are probably transient, having left their natal group in search of a new group.<ref name="MonkeyWorlds"/><ref>{{Cite web|title=Blue monkey|url=https://www.projectnoah.org/spottings/7087474|website=Project Noah|access-date=2020-05-25}}</ref><ref>{{Cite web|title=Blue Monkey|url=https://www.reachafricanwildlife.com/blue-monkey/|website=Get to African Wildlife safaris|language=en-US|access-date=2020-05-25}}</ref>

====Social relationships====
In these female-bonded societies, only 5&ndash;15% of monkeys' activity budget is occupied by social interactions and the most common social interactions within a group are grooming and playing.<ref name=Cords86>{{cite journal |last=Cords |first=Marina |year=1986 |title=Interspecific and Intraspecific Variation in Diet of Two Forest Guenons, ''Cercopithecus ascanius'' and ''C. mitis'' |journal=Journal of Animal Ecology |volume=55 |issue=3 |pages=811–827 |jstor=4418 |doi=10.2307/4418|bibcode=1986JAnEc..55..811C }}</ref><ref name=Cords>{{cite journal |last=Cords |first=Marina |year=2002 |title=Friendship among adult female blue monkeys (''Cercopithecus mitis'') |journal=Behaviour |volume=139 |issue=2–3 |pages=291–314 |doi=10.1163/156853902760102681 |citeseerx=10.1.1.505.6980 |s2cid=145357186 }}</ref><ref name=Gathua>Gathua JM. 2000.

[[Alloparenting]] is common among blue monkeys. The most common infant handlers are juvenile females, and usually one infant is carried by a number of alloparents. One hypothesis is that this allows the infant to learn to socialise at an early stage in life.<ref name=Forster/>

Interesting female-female relationships exist among blue monkeys. This relationship is believed to be shaped by their feeding ecology, which, in turn, is shaped by between-group and within-group competition.<ref name=Pazol/> Blue monkey females exhibit strong, aggressive competition between groups<ref name=Cords86/><ref name=Cords/><ref name=Payne/> and between other species because of their territorial character,<ref name=Cords/><ref name=Payne/> but milder though more frequent competition within groups.<ref name=Cords/> Though earlier beliefs were that blue monkeys are not territorial, more current extended research<ref name=Payne/> shows that earlier researchers misinterpreted the results because social interactions overall are infrequent. Moreover, overall [[agonism]] rates in blue monkeys are very low.<ref name=Cords/><ref name=Pazol/> Within-group conflicts are mild and infrequent because females distance themselves from one another and feed at different sites to avoid competition.<ref name=Cords/><ref name=Pazol/> Although blue monkeys were believed to be egalitarian, current extended research confirms that linear dominance hierarchy occurs in female blue monkeys,<ref name=Cords/><ref name=Payne/> which becomes more apparent when food resources are scarce.<ref name=Cords/>
