''Cephalotes rohweri'' is a species of arboreal ant of the genus ''Cephalotes'', characterized by an odd shaped head, and the ability to "parachute" by steering their fall if they drop off of the tree they're on. Giving their name also as gliding ants.〔Latreille, P.A. (1802). Histoire naturelle, generale et particuliere des crustaces et des insectes. Vol. 3. ''F. Dufart, Paris''. 467 pp. (PDF )〕 == Characteristics== ''C. rohweri'' is most commonly found in the Sonoran Desert, where it establishes nests in abandoned beetle cavities in Palo Verde trees (''Parkinsonia florida'' or ''Cercidium floridum'').〔Species: Cephalotes rohweri. (n.d.). AntWeb. Retrieved December 15, 2013, from http://www.antweb.org/description.do?genus=cephalotes&name=rohweri&rank=species&project=allantwebants〕 They feed primarily on the pollen of these trees, and thus have little or no need to venture to the ground. However, they are capable of consuming other foods, and it has even been suggested that they may occasionally forage on the ground to do so. Colonies range in size between ~50-200/300 individuals, and frequently have multiple reproductive queens. Because brood require several months to mature into adults, queens cannot adjust the ratio of soldiers to workers quickly enough to adapt to changing threats. Therefore, an effective strategy of soldier (major) deployment has evolved to maximize survival.〔Creighton, W. S., & Nutting, W. L. (1965). The Habits and Distribution of Cryptocerus Rohweri Wheeler (Hymnoptera: Formicidae). PSYCHE, March, 59-63.〕
