Bombus rufofasciatus SMITH is a Tibetan species, widely distributed in the Oriental region. It is a medium tongued species abundant in both the north-east and north-west Indian Himalaya, covering an altitude range from 2400 to 4200 m. Because of its abundance and very wide distribution, it is associated with a sizeable number of host plants. Males and workers are similar in colour pattern, but the queen is a little different. The species shows a preference for highaltitude mountain slopes and is found in abundance in the open meadows of Affarwatt, Sheeshnag, Daksum, the Razdan Pass and the Lahul-spiti Valley of Himachal Pradesh in the north-western Himalaya. For preference it forages on Aconitum spp. (Ranunculaceae), Trifolium spp. (Papilionaceae), Cirsium spp. (Asteraceae) and certain members of Lamiaceae. Due emphasis has been laid on its detailed taxonomic descriptions, synonymy, host plants, pollination ecology, distribution pattern and illustrations. 51 food plants of this species have been recorded for the first time from the areas under study.
Bombus simillimus SMITH is a west Himalayan species, known only from Pakistan and India. In the Indian Himalaya this species is restricted to Kashmir, Himachal Pradesh and Uttarakhand. So far, it has never been recorded from other regions. Its females (workers) can be recognized by the chocolate brown pubescence of the metasomal terga 1 and 2. The colour pattern of the queen is very distinct, with the whole body coloured black except for the last two metasomal terga, which are brick-red. In Kashmir Himalaya it is widespread around the lower mountain coniferous forest and was found foraging heavily on Trifolium pratense, Lavatera cashmeriana, Carduus spp. and Cirsium spp. Being very common and having a very wide distributional range, it is associated with a sizeable number of host plants. Due emphasis has been laid on its detailed taxonomic descriptions, synonymy, host plants, distribution pattern and illustration. Thirty-five food plants of this species have been recorded from the study areas.
Bombus pyrosoma MORAWITZ is an Oriental species. In the Indian Himalaya it is widely distributed in Kashmir, Himachal Pradesh, Uttarakhand and Sikkim with a long seasonal activity period. Queens and males were examined from the Kashmir Himalaya during June, August and September with altitudinal distribution ranges from 2300 to 4200 m. The species is abundant from 3000 to 4000 m in the Kashmir Himalayan belt and was found foraging on large wild flowers in open areas of the mountains. It has a preference for some species of Lamiaceae, as well as Taraxacum officinale and Cirsium spp. (Asteraceae), and Trifolium spp. (Fabaceae). The queens are very large, whereas males are medium-sized. Both have very different colour patterns. Due emphasis has been laid on its thorough taxonomic descriptions, food plants, synonymy, distribution pattern and illustration.
