Data from: Florivory and floral larceny by fly larvae decrease nectar availability and hummingbird foraging visits at Heliconia (Heliconiaceae) flowers

Insect larvae inhabit the corolla tubes of some Heliconia species (Heliconiaceae). In this study, we present the first evidence of the influence of these larvae on the pollination ecology of Heliconia plants. We provide experimental evidence that the flowers of Heliconia spathocircinata infested by flies have less nectar for pollinators and received fewer visits by hummingbird pollinators, in comparison with uninfested flowers.昆虫幼虫栖息于部分蝎尾蕉属（Heliconia，蝎尾蕉科Heliconiaceae）植物的花冠筒内。本研究首次提供了此类幼虫对蝎尾蕉属植物传粉生态学产生影响的实验证据：相较于未被侵染的花朵，被蝇类寄生的卷苞蝎尾蕉（Heliconia spathocircinata）的花朵可为传粉者提供的花蜜量更少，且受到蜂鸟传粉者的访问频次更低。
