Upis ceramboides is a species of beetle, one of many wood-living insects that benefit from forest fires. It often occurs in quantities below the bark on the fire-damaged birches, but can sometimes be seen on other deciduous trees such as willow and aspen. The larvae thrive in the inner bark which is rich in mycelia, and in the sapwood. They develop into pupae during the summer months under the bark, and they develop over two or three years. The following spring they reproduce themselves.
