The Pliycitids {Phyc'i-tids), Our most common members of this family are small moths with rather narrow but long fore wings, which are banded or mottled with various shades of gray or brown. The family is, however, a large one and other types of col- oration occur. The dis- tinctive characteristics are those given in the table above. Figure 281 represents the venation of the wings. The larvae of the dif- erent species vary greatly in habits. Some live \i\ flowers, some fold or roll leaves within which they live and feed; some are borers; others feed upon dried fruits, or flour and meal; and one, at least, is preda- ceous, feeding on coccids. Usually the larva lives in a silken tube or case, lying concealed by day and feeding by Fig. 281.—Wings of Tlascala Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Comstock, John Henry, 1849-1931; Comstock, Anna Botsford, 1854-1930. joint author.
