Some moths use pareidolia to scare away predators by flashing scary “eyes”, others disguise themselves as twigs, bark, lichen, moss. Some opt to look like leaves, yet others have more than a passing resemblance to flowers. Others spend a lowly life looking like bird droppings. This one, however, the Buff Arches, has evolved to resemble a chunk of flint lying on a woodland floor.
