Life History

This species feeds on Hazel or Hornbeam and its larval mines are often found alongside that of Stigmella microtheriella in the same leaf. However the mines of S. floslactella are generally wider, less angular and contain more scattered frass than those of S. microtheriella. The egg is underside, in a leaf-axil, and the larva mines venter-down. The larval mines can be found in June-July, but more often in September-October.

UK Status

VC55 Status
