Family YPONOMEUTID^. 



This is the first of a series of families to which the term micro-lepi- 

 doptera may be applied with strict propriety, and small as the majority 

 are, many of them are veritable gems of beauty, far exceeding in bril- 

 liancy and richness their relatives of larger size. The wings are usually 

 narrow, sometimes lanceolate, with very long fringes, which are espe- 

 cially marked in the secondaries. The antennae are usually of moderate 

 length and slender, but sometimes very long, the head often set with 

 closely placed upright scales, appearing like a little plush cap. There 

 are some exceptions to this type, notably the little series of shaggy 

 forms allied to "Anophora"; but as a whole the characterization applies. 

 The distinctive features of the various families are not obvious to any 

 save the special student, and no attempt will be made to define them. 



The larvae are largely miners in leaves and vegetable tissue generally, 

 though a few live in or on animal matter. Many of them make charac- 

 teristic cases or mere tubes, in which they live, and among these the 

 "clothes moths" have a well deserved if not particularly good reputation. 



There are few collections of these species and our fauna is only im- 

 perfectly known.
