We show that the frontal gland of imagoes in Prorhinotermes species is well developed at the time of the nuptial flight, and filled with a complex mixture of sesquiterpene hydrocarbons and nitroalkenes. The composition varies between P. simplex and P. canalifrons, between geographically distant colonies of P. simplex (Cuba vs. Florida), and between different flights of closely related subcolonies. The volume of secretory cells decreases in functional kings and queens after colony foundation, and dealate reproductives lose the ability for biosynthesis, and their frontal gland is devoid of volatile compounds found in swarming imagoes.
