Tree Bumble BeeTree bumblebee nests are built above ground, preferably at height, and, as the name suggests, in trees. Bird boxes are often used and these bees have been known to evict nesting birds in order to use one. They appear to like living near us humans and there have been cases of their nests being made in tumble dryer vents – they like the fluff that can accumulate there.

The tree bumblebee feeds on a wide variety of plants and flowers, such as rhododendron, fuchsia and pussy willow. It is an important pollinator of raspberry and bramble.

Mostly seen from March to July, this is one of the first bees of the season. It has also been known in particularly good summers to have a second batch of offspring later in the year. However, some colonies die out early as they are prime prey for caterpillars.
