Research Abstract	Fossil cones and leaves of Picea species(Pinaceae) are often found, but the identification is sometimes difficult because the difference between species is slight. This study showed that the galls formed on Picea by adelgids(Hemiptera) are morphologically different not only between the insect species but also between the host plant species. The morphological description will be helpful for studies on historical botany.
