Its fore wings are ochreous brown. A very dark oblique streak, edged with yellow, runs from the inner margin of the base. A reddish patch in the centre of the wing, also edged with yellow, is narrow on the costa, and expands as it approaches the inner margin. Beyond this are another dark patch on the costa and two reddish-brown blotches on the hind margin. [Illustration: FIG. 224.--XYLOSTEANA WITH WINGS CLOSED.] The larva is greenish brown, marked with white spots which have black centres; and it feeds on oak (_Quercus Robur_), honeysuckle (_Lonicera Periclymenum_), and other plants, in the month of May. _Tortrix viridana_ In June and July this pretty but destructive little insect may be seen flying in abundance in almost every oak wood. Its fore wings are one uniform pale green with the exception of a streak of yellow along the costal margin; and, when at rest, scores may exist on a single twig without being seen unless closely examined. The hind wings are of a pale smoky tint, and rather glossy. The larva is green, with black spots, and feeds in May and June on the oak and other trees, often almost completely devouring the foliage. [Illustration: FIG. 225.--VIRIDANA.] _Peronea cristana_ This moth is not so generally abundant, but is very common in many of the woods of the south. It is remarkable for the large number of varieties that have been observed, many of which have been regarded as distinct species. [Illustration: FIG. 226.--CRISTANA--ENLARGED.] Its fore wings are of some shade of brown or grey, with a light streak of variable colour along the inner margin, and a tuft of raised white scales in the middle of the wing. It flies during August and September. _Ptycholoma lecheana_ Our last example of the family _Tortricidae_ is _Lecheana_, a moth that is common in most parts in June and July. [Illustration: FIG. 227.--LECHEANA.] Its fore wings are brown, lighter towards the base. There are no very distinct markings, but there is generally a darker patch in the middle of the wing, edged with a silvery streak on each side. The larva feeds on several trees, including oaks and elms, in the month of May. _Penthina pruniana_ [Illustration: FIG. 228.--PRUNIANA.] The next family--_Penthinidae_--contains the common species _Pruniana_, which may be readily known by its boldly marked wings. The basal portion of the fore wings, to the extent of nearly two-thirds of the whole, is very dark brown. The remaining third is almost white, and clouded with grey. The hind wings are smoky brown with a paler fringe. The caterpillar of this species feeds on the blackthorn (_Prunus spinosa_) in May, and the moth flies in June and July. _Antithesia salicella_ This moth is not nearly so common as the last species, but is fairly plentiful in some localities in the south of England. It belongs to the same family as _Pruniana_. [Illustration: FIG. 229.--SALICELLA.]
