In April, Business Eco reported on an effective way in which developers can preserve wildflower sites and the insects that rely on them.

The charity Butterfly Conservation urged developers across the region to back a scheme to protect the dingy skipper butterfly, pictured, which has suffered a massive decline over the past 25 years because of development of the brownfield sites on which it lives.

Butterfly Conservation is asking companies to create and preserve habitats on industrial sites, including old quarries, former colliery areas and the sites of former engineering plants, all of which harbour the bird's foot trefoil, the butterfly's main food source.
