Sparkfly

Sparkflies were small flying insects native to Dathomir. They had bio-electric luminescent bodies, which were used to signal other members of their species. The pointed end of their abdomen could release a painful electrical charge. Although a single shock would only leave a small burn, multiple "stings" could kill a humanoid.

Nightsisters once used the force to control swarms of sparkflies to attack the Broken Columns Clan, Falling Leaves Clan, and the Skywalker/Solos.
