Global Butterfly Week - May 30 to June 7 - is the first co-ordinated worldwide effort to monitor butterfly diversity through community science.

We're celebrating Global Butterfly week with a Caterpillar Carnival and Butterfly Ball activities including:

Our daily Butterflies and Bugs talk
Caterpillar of the Day board
A Conservation 'Promise' Tree
Sharing our team's favourite butterflies
Colouring and crafts
Spotter ID sheets
Nectar rich plant giveaway to visiting schools

A dedicated Global Butterfly Week matters because butterflies are far more than just beautiful insects - they are vital, hard-working components of a healthy planet. Because they are highly sensitive to environmental changes, their wellbeing tells us exactly how well our ecosystems are holding up.

An international spotlight helps protect them, and us, in several critical ways.

Essential polinnators for food systems

While bees get a lot of the credit, butterflies are key players in cross-pollinating wildflowers and crops. As they travel from bloom to bloom feeding on nectar, pollen sticks to their bodies and transfers to other plants. This process supports biodiversity and helps maintain healthy plant populations that form the foundation of local food webs.

Living Ecological Indicators

Scientists use butterflies as ecological indicators for climate change and habitat loss.

Rapid Response: Because butterflies have short lifespans and specific host plant needs, their populations react quickly to changes in the environment.
Tracking Shifts: Changes in their numbers or migration dates offer immediate, visible data on how climate shifts are impacting local wildlife.

Powering Global Citizen Science

Butterflies are highly visible and relatively easy to identify, making them the perfect gateway for community conservation. Events like Global Butterfly Week encourage people to step outside, log sightings and upload data to tracking maps.

This collective data gives scientists a huge, real-time picture of insect populations that would be impossible to gather alone.

Protecting the bottom of the food chain

Butterflies and their caterpillars are a massive food source for other wildlife. A booming insect population directly correlates with breeding success for songbirds and small mammals, which in turn feeds birds of prey. When butterfly populations crash, the entire food chain feels the squeeze.

Celebrating this global week isn't just about admiring our butterfly butterfllies - it's about coordinating international policy, building partnerships, reducing pesticide use and encouraging communities to plant native habitats so the entire natural loop stays intact.
