They turn, each, into a small gnat,

Not a blow-fly, bottle-blue;

Cecidomyia, vulgò, gall-gnat,

Galls both growths and growers too.

So the Farmers, full of trouble,

Help imploring go about,

They are told to burn the stubble;

No way else to stamp it out.

True the Chalcis is reputed,

On the Gall-gnat's grub to feed;
