Pollinarium bending—the most common form of pollinarium reconfiguration. (a) A pollinarium of the orchid Eulophia parviflora freshly affixed to a cetoniid beetle will bend in the direction of the yellow arrow as indicated in (b) with the pollinarium half bent. (c) After ca 100 s the pollinarium has reconfigured and the paired pollinia can be inserted into the stigma (white arrow) as the beetle backs out of a flower in the direction of the white arrow (shown in cross-section). Scale bar, 5 mm.
