1. Tongue:
Presence of tiny hairs with pores in them. They taste by passing food through these pores to reach the sensory cells. These tiny hairs are also found to be concentrated on the antenna and mouthparts of bumblebees.

Figure 4.3 Compound eyes and ocelli of bumblebee
3. Compound eyes:
Bumblebees like most insects have 2 compound eyes. Formed by a large number of ommatidia. There are three types of visual cells found in Bumblebees. They are green-sensitive, blue-sensitive and ultraviolet-sensitive.
The ommatidia lack focusing ability.
4. Ocelli:
Presence of 3 ocelli which detect changes in light intensity
