Bombus pascuorum, the common carder bee, is a species of bumblebee present in most of Europe in a wide variety of habitats such as meadows, pastures, waste ground, ditches and embankments, roads, and field margins, as well as gardens and parks in urban areas and forests and forest edges.

[3] The head of the common carder bee is of medium length and the snout is long compared to other species of bumblebee.

When queens search for suitable places to nest, they fly just above the vegetation, for example on forest edges, investigating cavities such as holes in the ground or niches in dead wood and grass.

The queen collects moss and grass to form a small, hollow sphere whose walls are partly bonded with wax and sealed off.

The adult worker bees, owing to the initially poor supply situation, are relatively small, reaching only about half the body length of the queen and lacking functioning ovaries.

In August the B. pascuorum nest, with a diameter of up to 15–20 cm (5.9–7.9 in), reaches a maximum population size from 60 to 150 individuals.

The common carder bee is polylectic, feeding on a variety of wild flowers, including nettles (Urticaceae), genuine motherwort (Lamiaceae), Himalayan balsam (Balsaminaceae), cabbage thistle, knapweed (Asteraceae), vetches, red and white clover (Fabaceae), monkshood (Ranunculaceae), fruit trees, etc.
