Commonly known as cuckoo wasps or emerald wasps, the hymenopteran family Chrysididae is a very large cosmopolitan group (over 3000 described species) of parasitoid or kleptoparasitic wasps, often highly sculptured, [1] with brilliant metallic colors created by structural coloration. [2]
In Polistes exclamans, equal sex ratio is obtained when only 46.3% of investment is devoted to females as female wasps are 1.16 times larger than male wasps. [16] In a study done by Strassmann, it was found that sexual investment is female biased, especially during years of high predation and when nests are generally less successful. [ 16 ]

Individual insects seem to do their own thing without any central control, yet the colony as a whole behaves in a highly coordinated manner. [ 66 ]
The wasps are a cosmopolitan paraphyletic grouping of hundreds of thousands of species, [1] [2] consisting of the narrow-waisted clade Apocrita without the ants and bees. [3] The Hymenoptera also contain the somewhat wasplike but unwaisted Symphyta , the sawflies.
