The crane fly (Tipulidae) - also known in the UK as the "daddy long legs"- is an insect I associate with the month of September. They are often seen during this month and during my working years there was a period when they regularly tripped the alarm of the building in which I worked. The engineer who was eventually called in to remedy the issue memorably said they must have been flying in formation. Why? Because a single crane fly passing through the beam would not trip it, but two within a short period would. This example was one of several on the door and windows at the front of our house one day.
