A Computational Fluid Dynamic Study of Hawkmoth Hovering [PDF]
ABSTRACT A computational fluid dynamic (CFD) modelling approach is used to study the unsteady aerodynamics of the flapping wing of a hovering hawkmoth. We use the geometry of a Manduca sexta-based robotic wing to define the shape of a three-dimensional ‘virtual’ wing model and ‘hover’ this wing, mimicking accurately the three ...

In a lomas desert ecosystem of coastal Peru, the columnar cactus Haageocereus acranthus shows traits and interactions consistent with a mixed‐vertebrate pollination system (hummingbirds and bats), with no detectable differences between flower colour morphotypes in either traits or interactions.

The roles of vision and antennal mechanoreception in hawkmoth flight control
Flying animals need continual sensory feedback about their body position and orientation for flight control. The visual system provides essential but slow feedback. In contrast, mechanosensory channels can provide feedback at much shorter timescales. How

Floral resource‐mediated multilayer networks: structure and pollinators' roles
Resource availability shapes interactions among free‐living species, particularly in plant–pollinator mutualisms, where the composition of floral resource types influences pollinator foraging. Bees, known for utilizing a broad array of floral resources, play a crucial role in these dynamics. However, how the structure of interaction networks vary among

Abstract Baobab trees (Adansonia) are iconic members of Madagascar's biota that serve as emblems for the island's unique biodiversity. Despite this recognition, many questions remain regarding evolutionary relationships and species limits within the genus.

Taxonomic complexity in the parasitic plant genus Cistanche: Evidence from phylogenomics
Abstract “Desert hyacinths” (genus Cistanche) are striking parasitic plants of historical and cultural importance that include species traded widely for herbal medicine. Despite the need for robust taxonomy, the application of names in the genus remains confused.

Learning of Multi-Modal Stimuli in Hawkmoths
The hawkmoth, Manduca sexta, uses both colour and odour to find flowers when foraging for nectar. In the present study we investigated how vision and olfaction interact during learning. Manduca sexta were equally attracted to a scented blue coloured feeding target (multimodal stimulus) as to one that does not carry any scent (unimodal stimulus; visual)

Here, the taxonomy of the genus Rhagastis Rothschild & Jordan, 1903 (Lepidoptera, Sphingidae, Macroglossinae, Macroglossini) from China is revised based on differences in wing morphology, male and female genitalia, and the phylogenetic relationship of ...

The predatory behavior of ants: an impressive panoply of morphological adaptations
This review focuses on predation in ants, showing the wide diversity of cases from solitary foraging to group hunting tactics, as well as the evolution of mandible shape frequently adapted to capture specific prey. Although most ants are generalist feeders, finding their sugary substances directly on plants or indirectly via sap‐sucking insects, some ...

First insights into herbivore–plant interaction of the spurge hawkmoth and Euphorbia cyparissias
The spurge hawkmoth Hyles euphorbiae (Lepidoptera, Sphingidae) is an insect herbivore feeding exclusively on spurges (Euphorbia). These are toxic due to their secondary metabolites including diterpene esters with numerous harmful biological activities ...
