Journal ArticleDOI
Dynamics of F-actin prefigure the structure of butterfly wing scales.
April Dinwiddie,Ryan Null,Maria Pizzano,Lisa Chuong,Alexis Leigh Krup,Hwei Ee Tan,Nipam H. Patel +6 more
TL;DR: The dynamics of the highly organized F-actin filaments during scale cell development are shown, and experimental manipulations of actin polymerization that reveal the essential role of this cytoskeletal component in wing scale elongation and the positioning of longitudinal ribs are presented.
Journal ArticleDOI
Biased learning affects mate choice in a butterfly
TL;DR: It is demonstrated that females are able to change their preferences in response to a single social event, and a role for biased learning in the evolution of visual sexual ornamentation is suggested.
Journal ArticleDOI
Differential Expression of Ecdysone Receptor Leads to Variation in Phenotypic Plasticity across Serial Homologs.
Antónia Monteiro,Xiaoling Tong,Ashley Bear,Seng Fatt Liew,Shivam Bhardwaj,Bethany R. Wasik,April Dinwiddie,Carole Bastianelli,Wei Fun Cheong,Markus R. Wenk,Hui Cao,Kathleen L. Prudic +11 more
TL;DR: Variation in phenotypic plasticity across serial homologous eyespots of the butterfly Bicyclus anynana, hypothesized to be under selection for similar or different functions in the wet and dry seasonal forms, is described.
Journal ArticleDOI
Artificial selection for structural color on butterfly wings and comparison with natural evolution.
Bethany R. Wasik,Seng Fatt Liew,David A. Lilien,April Dinwiddie,Heeso Noh,Hui Cao,Antónia Monteiro +6 more
TL;DR: This work demonstrated rapid evolution of violet structural color from ultra-violet brown scales in Bicyclus anynana butterflies with only six generations of selection, and identified the structural changes responsible for color evolution, which involve changes in the thickness of a chitin lamina in individual wing scales.
Journal ArticleDOI
Patterning of a compound eye on an extinct dipteran wing
April Dinwiddie,Stan Rachootin +1 more
TL;DR: Eohelea's wing organ is interpreted as the blending of these two developmental systems: the formation and patterning of the cuticle in the eye and of the wing, and the effective ecological environment in which these midges lived.
