Found in a bird box in Holywell Green at the home of Christine Eves, Scientific Society Treasurer, this Tree Bumblebee nest. They seem to like bird boxes as we have seen others this year in other gardens. This one had a solitary live bee in it.

Tree Bumble Bee Bombus hypnorum, which arrived from Europe and was first discovered in Wiltshire in 2001, is one of the commonest in Calderdale Gardens, having spread from the south.
You can see the typical bumble bee nectar cups they fill when they’re working the
flowers. They don’t thicken the nectar into honey by fanning it with their wings, as honey bees do.
