Of course, among so many species we are sure to find considerable variety in form and structure; but notwithstanding this, the _Tineae_ form a well-marked division, and the beginner will find but little difficulty in distinguishing between these and the other Micros. The wings are long and narrow, and are remarkable for the length of the fringe, particularly that of the hind wings. The bodies, too, are long and slender. The larvae are exceedingly variable. Some have the usual number of sixteen limbs, and others have as many as eighteen. Again, the larvae of several genera have only fourteen legs, and some are absolutely legless. With regard to their food and habits, they are equally variable, for while some feed exposed, others are always protected in rolled leaves. Some construct for themselves portable tubes, so that they always remain under cover, and are at the same time perfectly free to ramble in search for food. Some, also, are leaf miners; and the group includes the so-called 'Clothes Moths,' whose larvae devour our garments, furs, and the upholstering of our furniture. We shall now briefly notice a few species, in order that we may become better acquainted with the general characters of the group. _Diurnea fagella_ This moth represents the small family _Epigraphiidae_, containing only six species, all of which appear in the winter or early spring. The present species is very common in most parts, and may be seen at rest on the barks of trees in March and April. [Illustration: FIG. 234.--FAGELLA.] The fore wings are usually pale grey or yellowish grey, and dotted with brown; but there is a great variety both in the depth of the ground colour and the distinctness of the markings. Our illustration gives the usual appearance of the insect. The caterpillar feeds on various trees in September and October, always protected between leaves that it has spun together. _Adela cuprella_ The family _Adelidae_ contains ten species, all remarkable for the great length of their antennae. The one selected for illustration is a beautiful little moth with bright bronzy green fore wings, tinged with a rich glossy violet. The hind wings are brown with a glossy surface. [Illustration: FIG. 235.--CUPRELLA.] This moth does not seem to be widely distributed, but is fairly plentiful where it occurs. Wimbledon Common and Epping Forest are good localities for it. It is on the wing in April and May. _Hyponomeuta Padellus_ The family _Hyponomeutidae_ contains about twenty insects, some of which are very common and exceedingly destructive to our trees. In May and June hawthorn and fruit trees may be seen swarming with the gregarious larvae of some of them, and almost entirely stripped of their leaves. [Illustration: FIG. 236.--PADELLUS.] The species here figured has grey or white fore wings with three rows of black dots. The hind wings are darker grey without dots.
