Mantid nymph

"The articulation of the head is also remarkably flexible, permitting nearly 300 degrees of movement in some species, allowing for a great range of vision (their compound eyes may contain up to 10,000 ommatidia and have a large binocular field of vision). The dark spot on each eye is a pseudopupil. As their hunting relies heavily on vision, they are primarily diurnal, but many species will fly at night, especially males in search of less-mobile females whom they can detect through pheromones. Flying at night allows these males to avoid many diurnal bird predators, and many mantises also have an auditory thoracic organ that assists them as they attempt to avoid capture by bats by detecting the presence of the bat's echolocation sounds and responding evasively." - Wikipedia
