Examples of pollen placement strategies observed among chiropterophilous flowers and their pollinating bats. A Tarenaya longicarpa (Cleomaceae) flowers, with distinct yellow pollen marks are evident diffuse pollen placement on the wings of the bats; B Pseudobombax marginatum (Malvaceae) have big brush type flowers promoting diffuse pollen placement into bats. C Flowers as Bauhinia pentandra (Fabaceae) and D Ceiba gaziovii (Malvaceae) deposit pollen through unidirectional strokes, respectively in sternotribic and frontal directions. Flowers of Harpochilus neesianus (Acanthaceae) (E) and Xiquexique tuberculatus (Cactaceae) (F-G) employ a stamp-like mechanism, depositing pollen on the bats' bodies, respectively on the uropatagium and facial regions. In photos A and B, the nectar-feeding bat Glossophaga soricina (Glossophaginae, Phyllostomidae) is shown, while photo C features Lonchophylla sp. (Lonchophyllinae, Phyllostomidae)
