Anguina tritici

It causes a disease in wheat and rye called "ear-cockle" or seed gall.

Anguina tritici has a three part esophagus and the esophageal glands do not overlap with intestine.

Eggs laid by the female develop and hatch as J2 within the seed gall where they desiccate and become dormant.

It causes a disease called "ear-cockle", "gout" or seed gall on wheat and rye, and also infects barley and oat.

If compared to normal wheat seeds, galls are smaller in size, lighter, and their color ranges from light brown to black (normal wheat seeds are tan in color).
