Abstract:
... Eggs of the assassin bug genus Sinea have an expansion of the chorion called the corolla that gives the eggs a flower-like appearance. In 2016, corollae of S. rileyi Montandon were observed to open and close in the laboratory, prompting a study on the morphology and mechanism of this movement. Eggs of field-collected S. complexa Caudell, S. diadema (F.), S. integra Stål, and S. rileyi were used to ...

Abstract:
... Floral resources can be recognized by visitors through attractants that signal their presence. However, besides petals, it is still unclear how floral elements in heterantherous species are perceived by visiting bees. In this study, we aim to understand the role of stamens and petals of Pleroma granulosum and P. raddianum in attracting pollination bees, mainly by evaluating whether pollinator beha ...

The capitulum, which is the main ornamental part of chrysanthemum plants, consists of ligulate marginal ray florets, an attractive corolla (petals), and radially hermaphroditic disc florets, but no stamens. In Asteraceae species, the zygomorphic ray florets evolved from the actinomorphic disc florets. During this pro ...
