Prociphilus

Prociphilus is an aphid genus of the subfamily Eriosomatinae, which cause the plants they attack to produce galls.

The aphids reside and feed within the gall.

[1] The appearance of Prociphilus oriens is often said to presage the first snowfall in Hokkaido and Tohoku.

Prociphilus oriens is commonly called yukimushi (雪虫), literally translating to "snow bug", in Japan.
