 The colony cycle of Polistes exclamans is longer than that of northern wasp species , shorter than that of tropical wasp species and as such is in “ some respects intermediate between ” the two . Their cycle occurs between March and September . The first brood of workers emerges between May and July . It takes about nine to fourteen days for eggs to develop , though eggs in smaller nests and that are laid later in the season take much longer to develop : about thirteen to eighteen days for larva to develop , about thirteen days for pupa to develop , and about a total of six to eight weeks for an egg to develop into an adult . Reproductive wasps emerge later in August or September .
