In contrast, corneal nanostructures of the majority Detailed Description of Diverse Corneal Nanostructures Order of other insect orders have either been unexamined or examined by Order). These nanostructures can be grouped as follows. by methods that did not allow precise morphological character- (i) Nipple-like structures (Fig. 1A and Fig. S1) include the regu- ization. Here we provide a comprehensive analysis of corneal larly packed protrusions of Lepidopterans (Fig. S1A), irregular surfaces in 23 insect orders, revealing a rich diversity of insect packaging in Dipterans (Fig. S1B), and irregular packaging of corneal nanocoatings.
