A celebration of all things insect
Organised by the Royal Entomological Society, and supported by partner organisations throughout the UK and Europe, Insect Week is a celebration of all things insect.
Wherever you live, it’s an opportunity to take part in insect science, get to know insects, learn from experts, and have fun.
Insect Week 2025 will take place on 23-29 June.

Ommatidia
Dragonfly compound eyes are made of up to 30,000 separate facets or ‘ommatidia’.
Craftiest
