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]
The aim of the Handbooks is to provide illustrated identification keys to the insects of Britain, together with concise morphological, biological and distributional information. The series also includes several Check Lists of British Insects. All books contain line drawings, with the most recent volumes including colour photographs.

Chalcidoid wasps are small wasps (most within the range 0.5–5 mm). However the group does include the smallest known insect (Dicopomorpha echmepterygis males have a body length of 0.14–0.24 mm); the largest chalcidoids include Leucospis gigas with a body length of up to 21 mm [2] and Doddifoenus wallacei with a body length of up to 19.6 mm. [3]
These wasps are brood parasitoids of crabronid wasps, bees, and eumenine vespids. [2] They are generally kleptoparasites, laying their eggs in host nests, where their larvae consume the host, egg, or larva while it is still young, then consuming the provisions. [1] The ovipositor is tube-like, and used to slip the eggs into the host nests.
The extinct family of Armaniidae also was formerly considered to be a group of "ant-like wasps" and was also classified under Vespoidea. [ 4 ] [ 5 ] However, additional work by Borysenko in 2017 found these species to be basal members of Formicidae , placing three genera under Sphecomyrminae and considering the rest incertae sedis .
The hymenopteran family Platygastridae (sometimes incorrectly spelled Platygasteridae) is a moderate-sized group (about 1100 described species) of exclusively parasitoid wasps, mostly very small (1–2 mm), black, and shining, with geniculate (elbowed) antennae that have an eight-segmented flagellum.
Citronellol is used in perfumes and as a fragrance in cleaning products. In many applications, one of the enantiomers is preferred. It is a component of citronella oil, an insect repellant. [2] Citronellol is used as a raw material for the production of rose oxide.
