Dokuga

Appearing only in the game Bleach: Dark Souls, Dokuga, whose name means Poison Moth, are toxic insects that infest the Rukongai. Their pale brown coloring makes them easy to mistake for Jigokuchō, the hell butterflies used elsewhere in the setting, though these creatures are a hazard rather than a helper.

The moths turn up in dangerous numbers and pose enough of a threat that ordinary Soul residents cannot safely walk outdoors while they linger. A quirk of the game's art notes an inconsistency in how they are drawn: although the moths are said to be light brown, their in-game sprite is rendered in orange.

When a swarm overruns West Rukongai, an elderly Soul asks Ichigo Kurosaki to thin their ranks, and once he clears them the grateful elder notes that people can again move about without fear. In a separate incident, Yasutora Sado rescues Kai from a group of Dokuga that ambush him while he searches for misplaced Soul Candies.
