Rabdophaga rosaria forms Camellia galls (also known as a terminal rosette gall) on willow (Salix) species.

R. strobilina is a close relative of R. rosaria and the larva of strobilina live under the modified leaves of the galls made by rosaria larva.

If there are many larva of strobilina, the gall can enlarge and change shape from a rosette, into a 30–40 mm long cone-shaped artichoke.

[3] The insect or gall has been found in Belgium, Denmark, Turkey and the United Kingdom.
