As a rule the larva hybernates through the winter, is full grown in the following May, and the moth appears in July; but in Scotland the caterpillar does not spin its cocoon till September, hybernates in the chrysalis state, and emerges in the following June. The same is true of the Cornish Eggars; but along the coast of South Devon both varieties are to be met with. The male Eggar seems to enjoy the bright sunshine, for I have seen large numbers flying over the rugged cliffs of the south-west throughout all hours of the day. _The Drinker_ (_Odonestis potatoria_) The popular name of this species is applied on account of a peculiar feature of the larva, which sucks up the dewdrop that lies on its food plant. The colour of the male is tawny and brown, with a reddish tinge; that of the female is yellow. The front wing has an oblique dark bar passing from the apex to the middle of the inner margin; also two white spots--one in the middle of the wing, and the other between it and the costal margin. [Illustration: FIG. 128.--THE DRINKER--MALE.] The caterpillar is dark bluish grey above, and has a line of orange spots on each side. Along the spiracles are oblique orange streaks, and a series of tufts of white hair. It feeds on the annual meadow-grass (_Poa annua_), and several other grasses. It is a hybernator, commencing its caterpillar state in the autumn, and reaching its full dimensions about the end of the following May. The moth flies during July and August. _The Lappet_ (_Lasiocampa quercifolia_) Our last example of the _Bombycidae_ is the Lappet (Plate X, fig. 6), a large moth, the female often measuring considerably over three inches from tip to tip. The wings are of a rich reddish brown, and exhibit a beautiful purplish bloom in a newly emerged insect. Scalloped black lines pass transversely across each wing, and a small black dot lies near the centre of the fore wings. The caterpillar is very variable in colour, but is usually grey or reddish brown. A deep purple band lies between the second and third segments, and another between the third and fourth. On the twelfth there is a small hump, and a pale stripe, more or less distinct, runs along each side. It feeds on the blackthorn (_Prunus spinosa_), buckthorn (_Rhamnus catharticus_), and the white willow (_Salix alba_). The moth is not uncommon, and is on the wing in June. Family--ENDROMIDAE _The Kentish Glory_ (_Endromis versicolor_) The beautiful Kentish Glory is the only British representative of its family. The male is shown in Plate X (fig. 7); the female is larger and similarly marked, but its colours are not so bright. This moth is not common, but may be seen occasionally in the birch woods of the southern counties. The males fly rapidly in the bright sunshine, but the females must be searched for on the bark and branches of the trees.
