[1] The typical insect is 1/30 of an inch long, orange red, with whitish wings hairy on the edges, and black eyes.

They deposit their eggs in the centre of the corolla of the wheat flower, coming out in great numbers between 7 and 9 p.m. early in June, several laying on the same ear.

The larvae, footless grubs nearly an eighth of an inch long when fully grown, feed upon the flower, rendering it abortive, and not upon the stem like the Hessian fly.

An insect considered by Harris the same appeared in northern New England about 1828, whence it spread to Canada, Massachusetts, and New York, and disappeared only by being starved out by a change of crop or the substitution of late sown spring wheat.

In the late 19th century, the most efficacious remedies were: fumigations with sulphur for several evenings in succession while the grain was in blossom, lime and ashes strewn over them when wet with dew, liming and ploughing the soil into which they have burrowed, and sowing late in spring or early in autumn.
