Hydnora africanaFrom
Botanical Society of America Online Image CollectionHere are the dung beetles that visited the Hydnora flowers of the plant cultivated in Claremont, California in 1979. Notice their bodies have some whitish hairs on them; pollen could adhere to these hairs. Flowers pollinated by beetles usually have some tissue that offers beetles as food. In Hydnora, that's the whitish tissue on the inside of the "sepals." But beetles don't confine their feeding to such special "bribe" tissues. Beetles eat pollen and then eat the cells of the stigma. Beetle-pollinated flowers usually have an abundance of pollen and an abundance of stigma areas, and Hydnora flowers are no exception. By producing excess pollen and stigma cells, beetle-pollinated flowers succeed in achieving pollination and producing seeds despite the feeding habits of the beetles.

Hydnora africanaFrom
the Botanical Society of America Online Image CollectionThe threads that cross the gaps between the "sepals" of the Hydnora flower when the flower opens are pulled apart after a few days. Any beetles that entered the flower through those threads can now easily escape.
