BUCCULATRIX Zell. 



Small species that often occur in large numbers on tree trunks in May 

 and June. Larvae are leaf miners in early stages, later feeding externally. 

 When mature they spin a slender silken cocoon with longitudinal ribs or 

 ridges, which are characteristic for the genus. Hibernate as pupa.

PHYLLONORYTER Hbn. 



All the species of this genus = "Lithocolletis" Hbn., are leaf miners, 

 and as their habits throughout are very similar, individual dates and 

 localities are mostly omitted. The earliest mines are found late in July 

 and until frost there are two or more broods, frequently overlapping.
