Lepidoptera The Wall Butterfly Butterfly – Pararge Megara
Belonging to the same genus is another very familiar butterfly -the Wall-which receives its popular title from its peculiar habit of frequently resting on walls and stony banks. It is one of the first, if not the first, to take to the wing in the morning, and is generally the last to seek its hiding place in the evening. I have seen it actively flying about during August, as early as 7.30 in the morning, and found it still flitting from one spot to another along the western side of a wall as late as 8 in the evening, as if in search of a convenient shelter for the fast approaching night.
This pretty ‘Brown’ must be familiar to the reader, and the coloured drawing on
The Wall is a double-brooded butterfly, the first brood appearing in May, and the second in August. The caterpillars which produce the latter may be found on the cock’s foot (Dactylis glomerata) and other grasses in June, while those of the former are hybernators; and the chrysalides of the two broods may be found in April and July respectively.
The colour of the caterpillar is green, with a slightly darker stripe down the middle of the back, a pale stripe along each side, and another similar stripe about midway between these two.
The chrysalis is green with the exception of the more prominent parts of its surface, which are almost white.
This species is very common in almost every locality in Britain.
