I bought a book on the 'Ecology of Coccinellidae' by Hodek & Honek (1996). In the book, it says there's no record of a global extinction of ladybird species yet. This is because of their great mobility and the plasticity of their life cycle. In other word, even though ladybirds have existed for 280 million years long before the dinosaur age, they can still easily adapt with the ever changing environment and up to these days, ladybirds can survive in man-made surroundings, such as in agricultural plantations and even in urban cities. This explains the reason I could find a zig-zag ladybird feeding on ragi aphid on goosegrass growing next to a chemicals manufacturing factory and as well as a variable ladybird perching on a leaf of ornamental plant right in the middle of Bukit Bintang side walk!
