World Insect Week is an annual event organized by the Royal Entomological Society to celebrate and raise awareness about insects. This year's event runs from June 23rd to 29th. Join us as we explore the fascinating world of insects found deep in the rainforests of Hainan and discover their vital role in maintaining healthy ecosystems.

Damselflies VS Dragonflies

Over 160 species of dragonflies and damselflies have been observed in Hainan, 22 of which are endemic, or unique to the tropical island. These insects help regulate insect populations, and their presence indicates healthy aquatic environments.

Do you know how to tell the difference between damselflies and dragonflies? The key is in the eyes and wings! Find out more below and 'listen' to these two species introduce themselves. 

Colorful Butterfly Wing Mysteries

With more than 600 species of butterflies found on the island, Hainan is often referred to as the 'Butterfly Kingdom'. This is a fantastic time of year to see these valuable pollinators, with vibrant colors that stand out beautifully against the backdrop of flowers in gardens and along streets.

But do you know what makes butterfly wings so colorful? The secret lies in the complex chemical and structural systems of their wings. Most butterfly colors are due to the presence of pigments in the scales on their wings. Coloured pigments are molecules that absorb part of the light spectrum and reflect the rest. In addition to the chemical production of colors, there are physical phenomena linked to the layout of the scales: light spectrum interference causes some wavelengths to be added, while others are canceled out.

Moths Matter: Nocturnal Pollinators

When it comes to pollinators, it’s usually the bees, butterflies, and hummingbirds that get all the buzz for their essential role in the health of the world’s agriculture and ecosystems. However, evidence has been found that moths are important pollinators of a wide variety of plant species in diverse ecosystems.

While other insects are asleep, moths often play an invaluable role in pollinating flowers, particularly those that bloom at night or during the twilight hours. Take a look below to discover some lesser-known facts about these nocturnal beauties!
