First case of a computer bug being found: A moth lodges in a relay of a Harvard Mark II computer at Harvard University.

Moths are a group of winged insects of the order Lepidoptera, the other well-known members of which are butterflies; they are characterized by dark or dull patterned wings. They were previously classified as suborder Heterocera, but the group is paraphyletic with respect to butterflies and neither subordinate taxon is used in modern classifications.

Moths make up the vast majority of the order. There are approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, although there are also crepuscular and diurnal species.
