Description
The Scarce Swallowtail is a large distinctive butterfly, pale yellow/cream base colour boldly marked with black tiger-like stripes running from the leading edge of the forewings. The hindwings have orange and blue eye-spots and long tails making this a distinctive species which cannot be confused with any other species. In flight it is extreamly graceful and a joy to watch as it swoops, glides and flutters. Dispite its size and apparent fagility, it is magestic in flight, even on a breezy day.

A somewhat missleading name, the Scarce Swallowtail is infact quite common in central and southern Europe. The name 'Scarce' is the result of its status in the UK as it was at one time believed to be a very rare resident in Britain (Carter 1982) but is now known to be a very rare migrant. There is some confusion with this species. Those found in Spain and Portugal are often refered to as the Spanish Swallowtail or Spanish Scarce Swallowtail (Iphiclides feisthamelii), while butterflies from across the rest of Europe are known as Scarce Swallowtail (Iphiclides podalirius).

The solitary larvae spin silk pads known as resting sites on leaves of the foodplant. When the larvae venture off to feed, they use silk strands in order to trace their steps back to the resting site. The silk contains what is known as a unique volitile marker. This marker ensures that the larvae returns to its own rest site after feeding.
Habitat
Essentially a lowland species, usually associated with orchards, it can be found in hot, bushy places, flower meadows and clearings, roadside verges. It may also be seen 'hill-topping' on hot sunny days.
Distribution
Extinct in England as a breeding species c1850. The Scarce Swallowtail is an extremely rare migrant to Britain although any sightings which do occur may just as likely to be the result of accidental import or release by breeders.

The species feisthamelii occurs in Spain and Portugal and the extreme south of France around Roussillon, while ssp. podalirius is widespread in southern and central Europe.
