Anecdotally there has been an increase in Australia over the past five years, I see heaps of them whenever I go riding now and some about my house in suburbia.

Anecdotally there has been an increase in Australia over the past five years, I see heaps of them whenever I go riding now and some about my house in suburbia. I went to a small national park, a strip between two roads, and it was loaded with butterflies and dragonflies. It was like a disney film. It makes me think that vehicle pollution isn't their biggest threat but rather incecticides.
