This handsome species long known as _C. hera_, Linn., but for which Poda's
earlier name _quadripunctaria_ must be adopted, has its English home in
South Devonshire. The species had been recorded as British as far back as
1855, when one moth was taken at Newhaven in Sussex; in 1859 a specimen was
obtained in North Wales, two were taken in Sussex, 1868, and one was
captured in the Isle of Wight in 1877. The last-mentioned example was
kindly presented to me by the captor, Mr. Rowland Brown. For the county of
Devon, the earliest record is that of a specimen netted in a garden at
Alphington, near Exeter, in 1871, followed soon after by a report of others
at a place near Lodderwell. Ten or eleven years later the moth was found at
Dawlish, and in that neighbourhood and in other parts of a wide area
stretching from Exeter to Teignmouth, and perhaps further west, it has been
taken almost every year up to the present time (1907). Large numbers of
eggs have been obtained and distributed among entomologists, many of whom
have successfully wintered the caterpillars and eventually reared the
moths.

{165} The principal variation is in the colour of the hind wings and the
body, which usually are red, but in var. _lutescens_, Staud., are yellow;
between the red and the yellow forms there are all kinds of orange and
other intergrades. There is also variation in the black markings at the
inner angle of the fore wings, some or all of which are sometimes absent. A
specimen with the inner margin of the fore wings black instead of
creamy-white has been recorded, and a specimen with whitish hind wings is
stated to have been seen but not secured. The moth is shown on Plate 89,
and the early stages on Plate 88.
The eggs, which are laid in batches, are pale yellowish when deposited, but
assume a deep violet tint before hatching. Mr. W. Hewett (_Entom._ xxviii.)
states that in the case of seventeen female moths that he captured in
August, 1895, the average number of eggs laid by each was 133, and as
regards fourteen batches of eggs, the caterpillars hatched out in fifteen
or sixteen days.
When nearly full grown the caterpillar is blackish with an orange stripe
along the back and a series of creamy white spots on the sides; the hairs,
arising from shining light brown warts, are pale brown mixed with greyish
ones; spiracles black ringed with white, under surface greyish. Head black
and glossy. It hatches from the egg in the autumn and goes into hibernation
while still very small; reappearing in the spring and feeding on until
July, when it spins a flimsy silken web-like cocoon well down among moss
and litter. The food plants are dandelion, white deadnettle (_Lamium
album_), ground ivy (_Nepeta glechoma_), groundsel, plantain, nettle,
borage (_Borago officinalis_), and lettuce.
