About Bombus pascuorum (Scopoli, 1763)
Bombus pascuorum, commonly known as the common carder bee, has a yellowish or reddish-brown colored thorax. The body hair covering its first four abdominal segments is gray, while the hair on its fifth and sixth abdominal terga matches the thorax’s yellowish or reddish-brown coloration. This species displays size differences across its different castes and sexes. Queen body length ranges from 15 to 18 mm (0.59 to 0.71 in), with a total wingspan of 28 to 32 mm (1.1 to 1.3 in) and a proboscis (snout) length of 13 to 15 mm (0.51 to 0.59 in). Female worker body length ranges from 9 to 15 mm (0.35 to 0.59 in), with a total wingspan of 24 to 27 mm (0.94 to 1.06 in) and a snout length of 12 to 13 mm (0.47 to 0.51 in). Male drones have a body length ranging from 12 to 14 mm (0.47 to 0.55 in), a total wingspan of 24 to 27 mm (0.94 to 1.06 in), and a snout length of 10 to 11 mm (0.39 to 0.43 in). The common carder bee has a medium-length head, and its snout is longer than the snouts of most other bumblebee species.
