Section view of a Sarracenia flower. Note the pollen fallen from the anthers on the umbrella and the narrow space where the pollinators must enter to reach the pollen. Even by simply eating the petals, the pollinator would carry pollen to the next flower. Source: Wikimedia.

Angiosperms are the most widespread and diversified group of plants on Earth. They achieved such success during the Cretaceous radiation partly thanks to pollination of their flowers by insects. While attracting pollinating insects, the plant must repel predators and parasites. Some of these are florivore, flower eaters, that appear to be the forme...

... short, they became the petals of the modern flower. In addition to eating the pollen, the insects could then eat the petals and carry the pollen fallen or rubbed on them (Fig.1) 28 . ...
Context 2
... the morphology of the flower can also provide shelter and, combined with secretions, oviposition sites, although they appear to be rare cases. Morphology and orientation also allow to exploit the gravity to favour the release of pollen, like in the flower of Sarracenia (Fig.1). The orientation and morphology of the flower can increase the exposition to light. ...

Interactions with angiosperms have been hypothesised to play a crucial role in driving diversification among insects, with a particular emphasis on pollinator insects. However, support for coevolutionary diversification in insect–plant interactions is weak. Macroevolutionary studies of insect and plant diversities support the hypothesis that angios...
Simple Summary
Flowers are beautiful due to their perianth which is frequently colourful and conspicuous. The existence of the colourful perianth is closely related to insect pollination in extant angiosperms. The Early Cretaceous (1.25 million years ago) Yixian Formation in Northeastern China is famous for its great diversity of reproductive organ...
Simple Summary
Flowers are attractive to many people mainly due to their colourful and conspicuous perianth, which is closely related to successful insect pollination in extant angiosperms. The Lower Cretaceous Yixian Formation (125 million years ago) in Northeastern China is famous for its great diversity of early angiosperms. However, unlike typi...
Angiosperms and insects are two most diverse groups of macroscopic organisms, and their relationship plays an important role in the current ecosystem. An angiosperm is usually attacked by multiple insects in the current ecosystem, which is a proxy of the complication of the ecosystem. However, such a complicate relationship appears lacking in the e...
