Zooming in on butterflies: mating

The female Brimstone was in the middle of the path, abdomen tilted upwards.  A sign of sexual receptivity?  On the contrary: it was a strong negative message for the sulphurous suitor trotting hopefully around her flattened wings. No doubt another male had got there first.
