National Insect Week is a biennial initiative in the UK. Usually held during the last week of June, the aim is to engage the general public with the importance of insects and entomology. The week is organised by the Royal Entomological Society and supported by a large number of partner organisations concerned with insect science, natural history and conservation. The week consists of hundreds of events and activities across UK, allowing the public to discover insects and meet the entomologists that study them. The popular National Insect Week Photography Competition is launched during the week and attracts entries from large numbers of amateur photographers. As well as promoting the importance of insect science to the wider public, National Insect Week particularly aims to encourage young people into entomology.
Past National Insect Week campaigns have been endorsed by HRH The Prince of Wales, Prof David Bellamy OBE, Chris Packham, Kate Humble and Mike Dilger.
The next National Insect Week will be 20–26 June, 2016.
