THE LITTLE ERMINE MOTHS. 



(Hyponomcutido:.) 



Inquiries concerning the Little Ermine Moths which attack 

 apple trees and hawthorn hedges are some years very numerous. 

 There are three species found on fruit, two only are important, one 

 the Apple Ermine, the other the Hawthorn and Cherrj^ Ermine. 

 The apple species was separated by Zeller and is known as 

 H. malhuUa, the hawthorn species is H. paddla, the name by which 

 our apple species has been previously recorded (2). The presence 

 of the Little Ermine 3Ioth larvse can readily be detected on account 

 of their web or nest-forming habits. 



The Apple Little Ermine Moth. 



(Hyponoiiuuta maliitcl/a. Zell.) 



The Small Ermine Moths or Eypotwmeutida-, of which there are 

 seven species found in Great Britain, are easily known by the leaden- 

 grey or white front wings liaving small black spots spread over them, 

 and by the habit of their larvre living under a nest of silk. Three 

 species attack fruit, namely, H. malindlci, Zell.. H. eronymella, L., 

 Don, and H. pndclla, L. The former is known as a fruit tree 

 pest attacking the apple; it has been recorded, however, as 

 H. padella, which it closely resembles. H. padella feeds on haw- 

 thorn, and ia France on plum and cherry ; in Italy on plum. 

 Although this last species is s.iid to be found ou apple, the nest made 

 by the larviii on hawthorn in this country certwinly differs from that 

 made on apple, being much looser. The form on the apple was 

 named innlirorcUri by Stainton (4), but was apparently sunk as a
