Lepidoptera The Glanville Fritillary Butterfly – Melitaa Cinxia
The pattern of the upper side of this Fritillary (Plate III, fig. 4) is very similar to that of Aurinia, but the ground colour is a uniform tawny brown, and the fringes of the wings are of a very pale straw colour, barred with black.
The under side of the fore wings is tawny brown, with straw-coloured tips bearing black markings. The hind wings have four alternate bands of brown and straw colour, and a patch of straw colour at the base. The marginal yellow band has six or seven black spots. The brown band next to it is divided into six segments with black borders, each with a black spot. The next yellow band has also a row of black spots. The inner fulvous band is very irregular; and inside this is the yellow base with six spots.
This is another local insect-very local indeed, for it seems to have been found only in a few spots outside its head quarters, the Isle of Wight. Those in search of it should carefully scan the rough cliffy parts of the island, wherever the species of plantain (Plantago Coronopus and P. maritima) are plentiful, these being the food plants of the larva. It first appears on the wing in May, but may be found till the end of June.
The caterpillars, which are black and spiny, with reddish head and legs, begin to feed in August, and as soon as the chilly weather sets in they hybernate in groups under the cover of a tent constructed by binding together leaves or blades of grass. In the spring they start out again, and feed till the end of April, at which time they change to dark brownish and smooth chrysalides.
