ButterflySemi-ellipticalOrnithopters are complex models that can carry complex missions and maneuver in tight spaces than the conventional UAVs. In this study, an ornithopter with flapping motion is developed with a wingspan of 60 cm. The study focuses on the wing shapes and wing materials used...
here in the Science Lab, the little things shine: the gigantic horn of a beetle; the impossible blue of a morpho butterfly; the changing metallic-sheens of dozens of bees and wasps; the transparent perfection of a Dobsonfly’s wing structure; the clever camouflage of moths (whose wings look...
it was shown that in the butterfly,Vanessa cardui, actin bundles in the scales were required for initial scale elongation and to orient the scale parallel to the wing membrane. On the morphological level, actin bundles are required for longitudinal...

Population history is also an important factor that shapes the individual response to suboptimal and extreme temperature stress, but again, heat stress has a more pronounced effect than cold stress. In light of global warming, our results add to the body of knowledge that cold-adapted species ...
