- ‘Within each pit are 60 to 70 sensors called sensilla in insects.’
- ‘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.’
- ‘Taken together, the antennae and their sensilla are the insect's window on the external world.’
- ‘Short sensilla on the maxillary and labial palps, serve to recognize pheromone and touch when the male mounts the female.’
Early 20th century: modern Latin, diminutive of Latin sensus ‘sense’.
