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.
Articles relating to insects, pancrustacean hexapod invertebrates of the class Insecta.They are the largest group within the arthropod phylum.Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae.
The scale insect Dactylopius coccus produces the brilliant red-coloured carminic acid to deter predators. Up to 100,000 scale insects need to be collected and processed to make a kilogram (2.2 lbs) of cochineal dye. [89] A similar number of lac bugs are needed to make a kilogram of shellac, a brush-on colourant and wood finish. [90]
By moving its mouthparts the insect mixes its food with saliva. [50] [51] Some insects, like flies, expel digestive enzymes onto their food to break it down, but most insects digest their food in the gut. [52] The foregut is lined with cuticule as protection from tough food. It includes the mouth, pharynx, and crop which stores food. [53]
Additionally 1702 insect species (28% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. [ 2 ]
