Drosophila adults have 2000 chemosensory neurons that reside within segregated compartments called sensilla. |
The sensory cells are organized into five external fields of campaniform sensilla and one internal chordotonal organ. |
It is hard to imagine a clearer, simpler demonstration of how important thermal sensilla are to the insects' feeding routine. |
Short sensilla on the maxillary and labial palps, serve to recognize pheromone and touch when the male mounts the female. |
The head is analogous to a statolith, the movements of which are monitored by fields of hair sensilla located on the head, neck, and prothorax. |
Taken together, the antennae and their sensilla are the insect's window on the external world. |
