1) I find the scruffiest bit of ground I can, with specific low-growing weeds that the types of butterflies I am wanting to photograph will go for.
2) I crawl along the ground on hands and knees, preferably at the side of the road where everyone can drive past and see me at my best.
3) When I find a butterfly I dive - head down, bum up - steadying myself until I have taken the photograph.
4) Eventually I arrive home, muddy, dirty and usually triumphant, but looking like I've been caught in a rugby scrum.
