I suppose that this insect sooner or later will turn up 

 also in Central Europe, but owing to its minute size the 

 structure of the antennae can be made out only under the 

 microscope, and it may therefore stand in some collections 

 among undetermined species of the genus Limnophila, to 

 which it bears a strong superficial resemblance.
