The galls of this species are found on the leaves or 

 stem of Nepeta glechoma, or on both. In shape they 

 are very irregular ; they may be spherical, pear-shaped, 

 or of no definite form ; they may occur singly or in 

 groups, separated or united ; in colour green — entirely 

 green, or green with pink or red, this latter being 

 more particularly the case with young species. They 

 are covered with long white hair, but this gets rubbed 

 off with age, and the galls are then glabrous. They 

 are polythalamous. At first soft and succulent, with 

 age they get hard and woody.
