PLATE 3.6. DRONE ANTENNA TIP, VENTRAL SURFACE

TOP Low magnification of the antenna tip. At least four morphological variations of the peg organs can be resolved, and most of these are close to the antenna terminus. The plate organs are located more posteriorly and are circumferentially arranged around this segment (x 306)

BOTTOM LEFT Higher magnification of the antenna showing thick pegs, plate organs, and pit organs. Each pit organ bears a curious bright margin around its orifice. Odor molecules enter the pit as easily as they penetrate the tiny pores that radiate out in spokelike fashion on the plate organs. (x 1,100)

BOTTOM RIGHT Thick-set peg organs and more slender, curved hairs, all set in sockets. The curling tips of some of these hairs may be the result of electron beam damage. (x 3,300)
