This insect makes galls on leaves, the edge of stems and fruits. The body length of the adult is around 180㎛. Its colour of the body is light yellow or light brown. There are five hairs on its sides, a long one at the edge of its tail and two on its thoracic leg. The colour of its eggs are white, and it is oval. The length of an egg is around 45㎛. Its nymph looks similar to the adult, but it is a little bit smaller and has two legs.

It appears 6 to 7 times a year. It stays the coldest season as an adult on Matrimony vine's dried leaves, fallen leaves or it remains underground. The period of the adult stage is around 25 to 30 days. After wintering, it digs inside of buds and creates galls from late March to early April. From May, you can find insect galls from the damaged part.

The adult spawns eggs in galls. Its nymph stays inside the gall and moves to another leaf after it becomes an adult. The damaged leaf turns yellow, stop growing and falls down. [Text source: Encyber]
