Orange-tip Butterfly

A female orange-tip butterfly on garlic mustard flowers. The female has black wing-tips rather than the bright orange wing-tips of the male. There were males flitting about but they were far too active to get a photo. At this time of year garlic mustard, also known as Jack-by-the-hedge, edges the path of the Serpentine Walk. It is an important food plant for the caterpillars of the orange-tip.
