trichoid sensillum of antennal segment 3 [FBbt_00004173]
Olfactory sensillum of antennal segment 3 whose external sensory part is a sharply pointed hair arising from a conspicuous cylindrical base. The walls of the hair are perforated by irregularly distributed pores connecting to a lymph filled lumen containing 1-3 ORN dendrites, unbranched except occasionally near the hair tip.

Olfactory sensillum of antennal segment 3 whose external sensory part is a sharply pointed hair arising from a conspicuous cylindrical base. The walls of the hair are perforated by irregularly distributed pores connecting to a lymph filled lumen containing 1-3 ORN dendrites, unbranched except occasionally near the hair tip.
Morphology is consistent with these sensilla being olfactory (Shanbhag et al., 1999). This function has been directly confirmed by electrophysiology (Clyne et al., 1997).
