Danish Clouded Apollo (Parnassius mnemosyne ssp. bang-haasi)
The Clouded Apollo (Parnassius mnemosyne (L.)) is native to the Palearctic, it inhabits meadows and woodland clearings; the species is divided into several subspecies, of which probably at least some are very likely invalid.
The Danish Clouded Apollo is thought to have indeed been endmic to Denmark, where several populations were found, for example on the islands of Funen, Langeland, Lolland-Falster and Zealand.
The form was last seen on Zealand in 1948 in the Knudsskov forest near Vordingborg, respectively in 1961 in the Nordskoven forest near the town of Jægerspris.
Antigua Gold Rim Swallowtail (Battus polydamas ssp. antiquus)
The Antigua Gold Rim Swallowtail, described in 1906, is a subspecies of the Gold Rim Swallowtail (Battus polydamus (L.)); it is thought to have been endemic to the island of Antigua in the Lesser Antilles.
This form is actually known only from a depiction by the British entomologist Dru Drury from 1770 (see below), however, it is quite possible that this form never existed in the first place as it is known that Drury’s book contains lots of geographical and taxonomical errors.
