Green bush cricket camouflage is conferred by bichromic protein processed from vitellogenin

Molecular mechanisms behind the green insect camouflage have puzzled researchers for ages. Here, we isolated water-soluble green protein from the integument of bush-cricket Tettigonia cantans. De novo sequencing and partial cloning revealed a fragmented form of vitellogenins, ubiquitous glycolipoproteins essential for embryonic development.
