Cymbopogon nardus, common name citronella grass, is a species of perennial aromatic plant from the family Poaceae, originating in tropical Asia. C. nardus cannot be eaten because of its unpalatable nature and is an invasive species that renders pastureland useless, since cattle will starve even in its abundance.
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.
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 Tiphiidae (also known as tiphiid wasps, [1] flower wasps, [2] [note 1] or tiphiid flower wasps [3]) are a family of large, solitary wasps whose larvae are parasitoids of various beetle larvae, especially those in the superfamily Scarabaeoidea. [4]
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.
Use citronella oil. Lady beetles dislike the smell of citronella oil, so it is recommended to spray it on warm and light color surfaces. Vacuum the bugs, don't squish them.
Like most of the Chrysidoidea, the Bethylidae are stinging Hymenoptera and most are parasitoids. Some of them, however, have developed their parasitoidal biology along predatory lines and they sting and malaxate their victims into paralysis.
