Fig. 5. The strong tiptop phenocopy displays a transformation of distal leg to antennae. (A) A normal antenna. (B) Close up of (A) showing antennal-specific sensory pegs (arrow). (C-F) Legs displaying the strong phenocopy. Tarsi and pretarsi are absent. The presumptive tibia (Ti) is the most distal segment and is transformed toward antenna based on its shape, a bristle density gradient and the presence of the antennal-specific sensory pegs (arrows in E,F). Fe: femur.
