食花性（花的消耗）发生在世界各地的现代被子植物中，与花粉和花蜜的消耗有关。然而，自早白垩世出现以来，食花动物仍然没有从化石中记录。我们测试的假设，最早的被子植物授粉由不同的昆虫动物群，评估7858株植物从8个地点的最新Albian达科他组从北美大陆中部，其中645个标本（8.2%）的花或花序。保存完好的标本可分为32个形态型，其中9个形态型表现出11种昆虫损害类型（DT）的207处损害，分别属于孔食性、边缘食性、表面食性和刺吸式4种功能性食性。我们评估了已知的食花动物对现代花造成的相同的DT，也是它们的传粉者，以及相关的昆虫口器类型造成这种损害。不同的，达科他州的食花传粉者社区表现出当地的模式，在布劳恩的牧场的花的形态型4和5有刺穿和吸吮为主导和边缘喂养为次要的相互作用，而Dakotanthus cordiformis在玫瑰溪I和II有一个相反的模式。我们没有发现任何偷花蜜的证据。这些数据支持快速出现的早期被子植物的食花动物和相关的传粉者公会在当地和区域社区水平上表达。
Florivory (flower consumption) occurs worldwide in modern angiosperms, associated with pollen and nectar consumption. However, florivory remains unrecorded from fossil flowers since their Early Cretaceous appearance. We test hypotheses that earliest angiosperms were pollinated by a diverse insect fauna by evaluating 7858 plants from eight localities of the latest Albian Dakota Formation from midcontinental North America, in which 645 specimens (8.2%) were flowers or inflorescences. Well-preserved specimens were categorized into 32 morphotypes, nine of which displayed 207 instances of damage from 11 insect damage types (DTs) by four functional-feeding groups of hole feeding, margin feeding, surface feeding and piercing-and-sucking. We assessed the same DTs inflicted by known florivores on modern flowers that also are their pollinators, and associated insect mouthpart types causing such damage. The diverse, Dakota florivore–pollinator community showed a local pattern at Braun's Ranch of flower morphotypes 4 and 5 having piercing-and-sucking as dominant and margin feeding as minor interactions, whereas Dakotanthus cordiformis at Rose Creek I and II had an opposite pattern. We found no evidence for nectar robbing. These data support the rapid emergence of early angiosperms of florivore and associated pollinator guilds expressed at both the local and regional community levels.
