The moth is taped to the machine's logbook.
"In 1947, Grace Murray Hopper was working on the Harvard University Mark II Aiken Relay Calculator (a primitive computer). On the 9th of September, 1947, when the machine was experiencing problems, an investigation showed that there was a moth trapped between the points of Relay #70, in Panel F. The operators removed the moth and affixed it to the log.... The entry reads: "First actual case of bug being found." The word went out that they had "debugged" the machine and the term "debugging a computer program" was born. Although Grace Hopper was always careful to admit that she was not there when it actually happened, it was one of her favorite stories." from: http://www.jamesshuggins.com/h/tek1/first_computer_bug.htm, retrieved 20100729
There is a google article about her 107th birthday (Dec. 9, 2013) where it describes the "bug" that she found while they were testing the computer (Mark I Electromechanical Computing Machine). The anecdotal story is that the moth they found was a bug and that they debugged the machine.
bug
moth in computer in 1952The term "bug" had been in use for any malfunction or error of a machine long before electronic digital computers existed.Its first use referring to a computer problem was on the Harvard Mark II electromechanical computer in 1947, when a moth got smashed inside the contacts of a relay causing a failure. When the failure was located and the moth removed from the relay, the operator on that shift taped it to the logbook below the entry on the failure and labeled it First Computer Bug. That morning Grace Murray Hopper came on duty and read the logbook and thought it was a great story to tell every time she spoke somewhere. The first computer bug wasn't even in an electronic computer, the Harvard Mark II was electromechanical.
The person who made it. It was actually a team of people. The term 'computer bug' was a result of the Navy Watch Officer finding a moth in between two of the computer relay contacts. Grace Hopper removed the moth and pasted it into the log book.

The term "bug" in the context of computer programming is believed to have originated from an incident in 1947 when a moth became trapped in a relay of the Harvard Mark II computer, causing a malfunction. Grace Hopper, a computer scientist, is often credited with the discovery and popularization of this term in the programming context.
Grace Murray Hopper is ofter given the credit for this term. She actually found a moth in the computer and framed it as a bug in the system.

The first COBOL specification was created by Grace Hopper, the woman who found a moth (bug) in a system.
