From a scientific standpoint, black butterflies, like any other nocturnal insect, seek shelter, food, or light sources. Some species of nocturnal butterflies, such as the Ascalapha odorata, known as the “death butterfly,” are attracted to artificial lights, which explains their presence indoors. Furthermore, they can enter homes in search of warm, sheltered places, especially during rainy seasons or during sudden temperature changes.

How to Manage Their Presence in Your Home

If a black butterfly enters your home, there’s no reason to be alarmed. You can help it leave by opening windows or doors, avoiding harming it. If their presence is constant, it’s a good idea to check for light sources that can attract them and minimize their use at night.
