Flower inspectors of Clerodendrum glabrum var. glabrum include ants as recorded in the photo. Many insects, notably bees, moths and butterflies, consume nectar and pollen here, while conveying clinging pollen grains from flower to flower, effecting the cross-pollination upon which so many plants depend.

Some observers of the ants (and other guests) may be poised to eat the visitors instead of the nectar, while others will photograph them or just admire the distances they climb, not being among the air travellers of nature.

Note the calyx lobes, far below those of the corollas in the photo. The bracts positioned even further below some flower pedicels are also visible at the hairy base of the clustered inflorescence (Coates Palgrave, 2002; Pooley, 1993; Schmidt, et al, 2002; www.plantzafrica.com).
