Morning Spiders and Night Spiders

  • In Japan, there is a superstition that is related to spiders like following:

    朝蜘蛛と夜蜘蛛


    “Let morning spiders get away even if they are your foes, kill night spiders even if they have children.”
    日本には、次のような蜘蛛に関する迷信があります。

    I was also told something like this superstition when I was child, but I’m not sure the reason.
    「朝の蜘蛛は仇でも逃がせ、夜の蜘蛛は親でも殺せ。」

    I found a theory that morning spiders represent visitors and night spiders represent thieves on the Internet, but there is no scientific basis.
    私もこのように教わったのですが、理由はよくわかりません。

    In general, house spiders are beneficial insects that eat injurious insects like flies or cockroaches, so I basically don’t kill spiders even when I find them at night.
    朝の蜘蛛は来客、夜の蜘蛛は泥棒を表しているという説をインターネットで見つけましたが、科学的な根拠はありません。
