PLATE 3.3. DRONE ANTENNA AND BASE

TOP. Drone antenna. There are twelve sections of the antenna. The drone antenna has far fewer trichoid sensilla (the very short white 11 whiskers" on the flagellum) than do queen and worker antennae (see Plates 1.6 and 2.4). (x 53)

BOTTOM RIGHT Higher magnification of the antennal base showing the basal knob of the scape inserting into the membrane-lined antennal socket. Microtrichia are abundant over this "membrane." Ranks of socketed (putative) mechanoreceptor hairs completely encircle the base. (x 347)

BOTTOM LEFT Articulation between two antennal (flagellar) sections. Each subdivision (they are not true segments) fits into the succeeding one without any real articulation or musculature. The base of each annular portion inserts into a small cavity of the one behind it. Spines are absent on the intersegmental membranes. (x 304)
