In search of swallowtails

A spring walk on Monte Acuto, in the Umbrian central Apennines, hunting fresh European swallowtail butterflies — scarce Iphiclides podalirius (also known as the pear tree or sail swallowtail) and the continental subspecies of the common Papilio machaon gorganus. Having spent many hours seeking glimpses of the britannicus British subspecies in the Norfolk broads, with it’s famously fussy larval feeding habits and adult sensitivity to habitat change, it seems remarkable how ubiquitous and numerous its southern cousin can be. The limestone grasslands on the climb were covered with spring flowers, with orchids and anemones at their seasonal best.
