image: Highly magnified image of nanoscale crystalline structures responsible for the coloration of T. opisena butterfly wing scales. The linear increase in size along the length of the wing scale gives clues into gyroid formation over time. This material relates to a paper that appeared in the April 26, 2017, issue of Science Advances, published by AAAS. The paper, by B.D. Wilts at University of Fribourg in Fribourg, Switzerland, and colleagues was titled, "Butterfly gyroid nanostructures as a time-frozen glimpse of intracellular membrane development." view more
