Morphometric studies of subgenus Megabombus (Hymenoptera: Apidae) from Jammu and Kashmir, India
Keywords:Caste, Hymenoptera, India, Megabombus, Morphometrics, Subgenus
The subgenus Megabombus comprises remarkably long-tongued species of bumblebees and remains usually more specialized in their selection of diversity of floral plants than other bumblebees for pollen and nectar resources. The subgenus Megabombus is described by only a single species from the North West Himalayan belt viz., Bombus albopleuralis Smith. This species is mostly familiar to exist at low highland habitats in the Indian Himalayan region with a long seasonal activity and is widely spread throughout North West and eastern Indian Himalayan region. The different caste members of this species viz., Queen, worker and male were recorded from different selected sites in the Union territory of Jammu and Kashmir. A total of sixteen morphological characters of Bombus albopleuralis were studied and later on, measured to find out the variations in different castes of Bombus albopleuralis and subsequently help in the identification of their different castes.
