Why are butterflies important?

Butterflies are bio indicators of a healthy environment and ecosystem - they are highly sensitive to changes in climate, pollution levels and harmful chemicals in the air

Butterflies are an important part of the food chain – butterflies are food for birds, bats and other insectivorous animals and parasites

Butterflies are excellent pollinators after bees, wasps and flies – without these wonderful insects, we would have a lot fewer plants!

Butterfly behaviour

 

Basking
Butterflies are cold blooded which means that they cannot regulate their body temperature. As a result, in order to generate enough heat and energy, butterflies spread their wings flat, orient themselves towards sunlight to get maximum exposure on their bodies.

     
 

Mud puddling
Mud puddling is the aggregation of butterflies, especially males in puddles to sip moisture and nutrients from the soil. The nutrients consisting mainly of sodium and nitrogen; increase male fertility and enhance reproductive success.
