The butterfly seems to be unknown in Scotland, and has only been
recorded from Killarney in Ireland. In England it is to be found in the
counties of Essex, Kent, Surrey, and Devonshire.
Its geographical distribution extends through Europe into Asia Minor,
East Siberia, and Northern Amurland. In Corea and Japan it is
represented by a larger form known as var. _niphona_.
The Glanville Fritillary (_Melitæa cinxia_).
This butterfly is bright brownish-orange with black markings, as shown
on Plate 71. The under side of the hind wings and the tips of the fore
wings are very pale yellowish; the former with two black-margined
brownish-orange bands, and lines of black dots; the tip of the fore wing
is also dotted and marked with black. The female is slightly paler, and
the markings are often blurred.
There is variation in the black markings on the upper side. Sometimes
these are enlarged, but more often they are much reduced, and the
central one may be completely absent from all the wings. Connected with
the suppression of the middle black line above there is usually
aberration on the under side of the hind wings also, where the central
area is clear of black dots, and the basal area is fulvous, edged and
marked with black. Two very remarkable aberrations are represented on
Plate 65, Figs. 7, 8.
The eggs, which are yellowish-white, and sometimes tinged with green,
are laid in a cluster on the under side of the tip of a leaf of the
narrow-leafed plantain (_Plantago lanceolata_). The caterpillars hatch
in July and August, and hibernate in companies under a web. The mature
caterpillar is black with white dots, and black bristles arising from
greenish warts. The red head, which is notched on the crown, and the red
fore legs distinguish this at once from the caterpillars of the Heath,
or the Marsh Fritillary. It feeds in early spring on plantain, but seems
to prefer _Plantago maritima_ to _P. lanceolata_ when both are present.
The chrysalis is brownish in colour, and is ornamented with orange on
the thorax, and with orange points and black marks on the body. It may
be found in April and early May suspended from the lower parts of the
stems of the plantain or other plants around. Newman states that he
found "dozens of the chrysalids in company," but I have only
occasionally met with them, and always singly.
