Insects on flowers
Insect biodiversity peaks in tropical rainforest environments where a large but as yet unknown proportion of species are found in the canopy. While there has been a proliferation of insect biodiversity research undertaken in the rainforest canopy, most studies focus solely on insects that inhabit the foliage. In a recent paper, we examined the distribution of canopy insects across five microhab...
متن کاملSimulation of the Coevolution of Insects and Flowers
Flowers need insects for their pollination and insects rely on the nectar and the pollen as a food resource. But instead of visiting all flowers, the insects limit their visits to a small number. This paper presents a simulation of the behavior of the insects which results in a specialized perception of blossom colors and fragrances by the insects. A coevolution can be observed only based on si...
متن کاملOdor-modulated navigation in insects and artificial systems.
Two pieces of information are absolutely required to locate a source of chemicals from a distance. The first and most obvious is the presence of the chemical cue, and the second is the direction of the flow of air or water carrying the chemicals. Insects orienting to wind while walking in terrestrial environments appear to use the mechanical deflection of their antennae to detect the direction ...

متن کاملFloral Symmetry Affects Bumblebee Approach Consistency in Artificial Flowers
Bilateral symmetry has evolved from radial symmetry in several floral lineages, and multiple hypotheses have been proposed to account for the success of this floral plan. One of these hypotheses posits that bilateral symmetry (or, more generally, a reduced number of planes of floral symmetry) allows for more precise pollen placement on pollinators. Greater precision would maximize the efficacy ...
