Stinging insects inject venom into their victims, whilst biting insects normally introduce anti-coagulants into their victims. The great majority of insect allergic animals just have a simple allergic response – a reaction local to the sting site which appears as just a swelling arising from the release of histamine and other chemicals

Traditionally, insects defined in this way were divided into "Apterygota" (the first five groups in the table) – the wingless insects – and Pterygota – the winged insects. However, modern phylogenetic studies have shown
