Scanning Electron Microscopy of Antennal Sense Organs in Prosapia bicincta (Say) (Hemiptera: Cercopidae)

The external morphology of the sensilla on the antennae of the adult spittlebug, Prosapia bicincta (Say) (Hemiptera: Cercopidae), is described for the first time, using scanning electron microscope observations. The sensilla include one peg-like basiconic sensillum (about 65.05 to 65.90 μ in length and 13.33 to 14.08 μ in width at base), 18 to 23 porous coeloconic sensilla (mostly 7.38 to 8.94 μ in diam), one campaniform sensillum and a cluster of trichoid sensilla (about 45 to 55 (μ long). The first two types of sensilla are located on the expanded flagellar base, while the latter two sensilla are on the pedicel.
