Summary
The hair-plate sensilla of the honeybee were examined by SEM and TEM. Apart from the normal single bristles, some were found with a threepronged point.
The dendrite runs eccentrically within the cuticular canal. Below the socket septum it is enveloped by sheath cells 1 and 2.
Sheath cell 2 also lines the remaining part of the cuticular canal and the subcuticular cavity continuous with the canal lumen.
From sheath cell 2, abundant lamellae project into the canal system. The lamellae seem to have a double-unit membrane with a somewhat granular appearance.
