The mouthparts of pollen-feeding species (all belonging to the genera <em>Heliconius</em> and <em>Laparus</em>) do not have structures exclusive to them. However, in comparison with non-pollen-feeding Heliconiiti, the pollen-feeding species have a significantly longer proboscis without elongation of the tip-region ; the bristle-shaped sensilla trichodea were found to be significantly more numerous and longer on the proximal and mid-region of the proboscis, while the sensilla of the tip-region are significantly shorter. In addition to these proboscis features, the labial palpi were shorter in the pollen-feeding species, which is likewise possibly associated with pollen-feeding behavior.

Antisera raised against the insect neuropeptides Callitachykinin II (CavTK II), Locustatachykinin I (LomTK I), and Leucokinin I (LK I) were used. Callitachykinin immunoreactive (CavTK–IR) neurons were detected from the 1st-instar larva throughout development to adult. The number of CavTK–IR cell bodies in the brain was 4–16 in larval stages, 10–84 in pupal stages, and over 140 neurons in the newly emerged fly. With the CavTK antiserum, the fibers of only 4 descending neurons were detected in thoracico–abdominal ganglia throughout development. The antiserum to LomTK displayed the same neurons as that to CavTK II as well as a small number of additional neurons. Notably, there were seen about 14–20 locustatachykinin-like immunoreactive (LomTK-LI) cell bodies in the thoracico–abdominal ganglia throughout development. Leucokinin-like immunoreactive (LK-LI) neurons were labeled throughout postembryonic development. In the brain, 2–4 LK-LI cell bodies were labeled from 1st-instar larva to 8-day-old pupa, and 6 LK-LI cell bodies were labeled in the adult brain. In the abdominal ganglia, 7 pairs of LK-LI cell bodies were labeled from 1st-instar larva to 96-h-old pupa, 8 pairs in 8-day-old pupa, and 9 pairs in newly emerged fly, respectively. The CavTK containing neurons in the brain displayed a drastic increase in numbers from larval stages to adult, which indicates an addition of functional roles for this type of peptide. During earlier pupal stages, the number of CavTK–IR neurons decreased. The LK-LI neurons, however, were strongly immunoreactive throughout postembryonic development. Only one additional pair of cells appeared in the brain and 2 additional pair of cells appeared in the abdominal ganglia of the adult as compared with larvae.
