The dragon mantis (Stenophylla cornigera) is a particularly elusive species, expertly hidden in the dense foliage of the Brazilian Atlantic rainforest with its leafy appendages and twig-like body. It's so hard to spot, in fact, that researchers aren't sure how many are out there—it could be that the species is incredibly rare or that it's incredibly hard to find.8
During a 2019 expedition, entomologists tracked down two adult males at night using a light trap, proving their theory that this nocturnal species navigates by moonlight. As researcher Leonard Lanna told National Geographic, "This mantis is considered legendary among specialists. Seeing a live one is something few people have done."9
