Stigmella floslactella (Haworth, 1828)
[Lepidoptera: Nepticulidae]


Tinea floslactella Haworth, 1828. Lep. Brit.: 585.
Stigmella floslactella
(Haworth, 1828).


Leaf-mine: The early gallery is filled with frass, later leaving clear margins (British leafminers). Like Stigmella microtheriella the larva feeds on hazel or hornbeam, and its mines are often found alongside that species 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 (UKMoths).

Larva: The larva is a dull yellow, head pale brown (British leafminers).

Pupa: Details unknown.

Hosts in Britain:

Betulaceae      
Betula     Emmet, 1974a
