AERODYNAMIC ANALYSIS OF MORPHING WING.

open access: yesGraduate Research in Engineering and Technology, 2022
This thesis presents a modelling and design exploration study of a novel twisting wing whose motion is enabled by a tensegrity mechanism. First, the aerodynamic characteristics of the twisting wing, which does not require control surfaces to modulate its shape, are compared with those of a conventional wing having a control surface.

Wing polymorphism in Dorypteryx domestica (Smithers) (Psocoptera: Psyllipsocidae) [PDF]

open access: yes, 1998
New wing morphs of the synanthropic psocid Dorypteryx domestica are described, including wing morphology and body measurements. These forms are intermediate in wing length and other morphological traits between normal brachypterous and fully macropterous

Differential Attraction of Summer and Winter Morphs of Spotted Wing Drosophila, Drosophila suzukii, to Yeasts. [PDF]

open access: yesJ Chem Ecol
Drosophila suzukii is a pest of soft and stone fruits that is attracted to yeast volatile metabolites. Drosophila suzukii has distinct summer and winter morphs which are found in different habitats.

iTRAQ-Based Comparative Proteomic Analysis Reveals Molecular Mechanisms Underlying Wing Dimorphism of the Pea Aphid, Acyrthosiphon pisum

open access: yesFrontiers in Physiology, 2018
Wing dimorphism is a widespread phenomenon in insects with an associated trade-off between flight capability and fecundity. Despite the molecular underpinnings of phenotypic plasticity that has already been elucidated, it is still not fully understood ...

Cell Cycle Progression Determines Wing Morph in the Polyphenic Insect Nilaparvata lugens

open access: yesiScience, 2020
Summary: Wing polyphenism is a phenomenon in which one genotype can produce two or more distinct wing phenotypes adapted to the particular environment. What remains unknown is how wing pad development is controlled downstream of endocrine signals such as

Data from: Wing shape variation associated with mimicry in butterflies [PDF]

open access: yes, 2013
Mimetic resemblance in unpalatable butterflies has been studied by evolutionary biologists for over a century, but has largely focused on the convergence in wing color patterns.

Measurements of D. suzukii body and wing size. [PDF]

open access: yes, 2020
Mean (+/- SEM) of wing length, wing width and hind tibia length (mm) for laboratory-reared known morphs (winter and summer) of Drosophila suzukii, and field caught flies across the season.

Multiple cues for winged morph production in an aphid metacommunity. [PDF]

open access: yesPLoS ONE, 2013
Environmental factors can lead individuals down different developmental pathways giving rise to distinct phenotypes (phenotypic plasticity). The production of winged or unwinged morphs in aphids is an example of two alternative developmental pathways ...

New aeroelastic studies for a morphing wing

open access: yesINCAS BULLETIN, 2010
For this study, the upper surface of a rectangular finite aspect ratio wing, with a laminar airfoil cross-section, was made of a carbon-Kevlar composite material flexible skin. This flexible skin was morphed by use of Shape Memory Alloy actuators for 35 test cases characterized by combinations of Mach numbers, Reynolds numbers and angles of attack. The

Does wing shape of andromorph females of Calopteryx splendens (Harris, 1780) resemble that of males? [PDF]

open access: yes, 2015
Female limited polymorphism consists in the coexistence of two or more female morphs in the same population and is widespread among odonates. Generally, one female morph, the andromorph, resembles males in colour or, sometimes, also in morphology and ...
