In European folklore, particularly in Britain and Scotland, the timing of a spider sighting determines whether it is a good or bad omen. Seeing a spider in the morning is said to signal grief or misfortune, while seeing one in the evening is interpreted as a sign of good fortune or relief. Noon sightings fall somewhere in between and are usually seen as lucky. This distinction is preserved in the traditional rhyme:
“If you wish to live and thrive, let the spider run alive.
A spider in the morning brings grief and mourning.
A spider at noon brings luck soon.
A spider in the evening is good for relieving.”
The superstition may have been influenced by medieval associations between spiders and witchcraft, particularly in morning hours when shadows were longer and sightings could be more ominous. It may also reflect natural patterns in spider behavior—such as web building or visibility—that change throughout the day. Encouraging people not to kill spiders may also have served a practical function in agricultural societies, where spiders helped control insect populations in barns and food stores.
